Answer:
h(3)=20
Step-by-step explanation:
h(3)=h(3-2)*h(3-1)=h(1)*h(2)=-10*-2=20
Answer:
20
Step-by-step explanation:
h(1) = -10
h(2) = -2
h(n) = h(n-2) * h(n-1)
Let n=3
h(3) = h(3-2) * h(3-1)
= h(1) * h(2)
= -10 * -2
= 20

Two radio stations are playing this week's #1 hit song. One radio station plays the song every 18 minutes. The other radio station plays the song every 24 minutes. Both stations play the song at 3pm. How many minutes will pass before they play the same song again.
Answer:
72 minutes until they play again
Step-by-step explanation:
18+18+18+18=72
24+24+24=72
Answer: 72 minutes
======================================================
Explanation:
The GCF of 18 and 24 is 6, since this is the largest factor shared between the two numbers
18 = 6*324 = 6*4To find the LCM, we'll involve the GCF. The LCM of two numbers x and y is found by multiplying them, and then dividing over the GCF of them.
LCM of x and y = (x*y)/(GCF of x and y)
LCM of 18 and 24 = (18*24)/6
LCM of 18 and 24 = 432/6
LCM of 18 and 24 = 72
-----------
To help confirm this, we can list out the multiples of each
multiples of 18 are: 18, 36, 54, 72, 90, ...multiples of 24 are: 24, 48, 72, 96, ...We see that 72 is the lowest common multiple. This is the final answer because each station will play the same song 72 minutes apart.
The stations play the same song at 3 PM. Then 72 minutes later (4:12 PM), the same song is played again on both stations at the same time. Then at 5:24 PM, another 72 minute gap, is when the same song is played again at the same time. And so on.
----------
Side note: 72 minutes = 60 min + 12 min = 1 hr, 12 min

Answer:
Zoom it to see well
Step-by-step explanation:
The equation of the parabola is y = (x - 1)² - 4. Then the vertex of the parabola is at (1, -4) and the parabola passes through (0, -1) and (0, 3).
What is the parabola?It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The equation is given below.
y = (x + 1)(x - 3)
We know that the equation is a parabolic equation.
And the value of y at -1 and 3 is zero.
The equation can be written as
y = x² - 2x -3
y = (x - 1)² - 4
And the vertex of the parabola is at (1, -4).
The graph is shown below.

If g (x) is the inverse of f (x) and f (x) = 4 x + 12, what is g (x)
g (x) = 12 x + 4
g (x) = one-fourth x minus 12
g (x) = x minus 3
g (x) = one-fourth x minus
Answer:
[tex]g(x) = \frac{1}{4} x - 3[/tex]Step-by-step explanation:
Since g(x) is the inverse of f (x) to find g(x) must first find f-¹(x)
To find f-¹(x) equate f(x) to y
That's
f(x) = y
y = 4x + 12
Next interchange the terms x becomes y and y becomes x
That's
x = 4y + 12
Next make y the subject
4y = x - 12
Divide both sides by 4
[tex]y = \frac{1}{4} x - 3[/tex]Therefore
[tex]g(x) = \frac{1}{4} x - 3[/tex]Hope this helps you

There are four points on a line: A, B, C and D, so that AB=1, BC=2, CD=4. Find all the possibilities of the length of segment AD.
Answer:
{1, 3, 5, 7}
Step-by-step explanation:
There are four possibilities:
AD = AB -BC -CD = 1 -2 -4 = -5
AD = AB +BC -CD = 1 +2 -4 = -1
AD = AB -BC +CD = 1 -2 +4 = 3
AD = AB +BC +CD = 1 +2 +4 = 7
Possible lengths of AD are 1, 3, 5, 7.
__
The negative sign means the segment is added toward the left instead of toward the right. A final negative value means D is left of A, instead of to the right.

Graph the solution of 7x+3<−4 or 2x−3≥9
Answer:
Step-by-step explanation:
To do this you would simplify both sides.
For the first one:
[tex]7x+3<-4[/tex]
[tex]7x<-7[/tex] (subtract 3 from both sides)
[tex]x<-1[/tex] (divide 7 from both sides)
and for the second one:
[tex]2x-3\geq 9[/tex]
[tex]2x\geq 12[/tex] (add 3 to both sides)
[tex]x\geq 6[/tex] (divide 2 from both sides)
When you graph these they will look like these pictures
Answer:
[tex]x<-1[/tex] and [tex]x\geq6[/tex]
Step-by-step explanation:
[tex]\bf 7x+3<-4[/tex]
You must subtract 3 from both sides.
[tex]7x+3-3<-4-3\\[/tex]
After subtracting, we got
[tex]7x<-7[/tex]
Let's make it into a fraction and divide
[tex]\frac{7x}{7}<\frac{-7}{7}[/tex]
Now we got the answer
[tex]x<-1[/tex]
[tex]\bf 2x-3\geq 9[/tex]
You must add 3 to both sides.
[tex]2x-3+3\geq 9+3[/tex]
After adding, we got
[tex]2x\geq 12[/tex]
Let's make it into a fraction and divide
[tex]\frac{2x}{2} \geq \frac{12}{2}[/tex]
Now we got the answer
[tex]x\geq 6[/tex]
Your answer is [tex]\bf x<-1[/tex] or [tex]\bf x\geq 6[/tex].

Find the measure of the remote exterior angle. m∠x=(197−5n)°m∠y=(6n+22)°m∠z=(n+7)°
A. 14
B. 91
C. 21
D. 127
Answer:
D. 127°
Step-by-step explanation:
The exterior angle (x) is the sum of the remote interior angles (y, z).
Setupx = y +z
(197 -5n) = (6n +22) +(n +7) . . . . . substituting the given expressions
SolutionEliminating parentheses and collecting terms, we have ...
197 -5n = 7n +29
168 = 12n . . . . . . . . . add 5n-29
14 = n . . . . . . . . . . divide by 12
Then the measure of remote exterior angle x is ...
m∠x = (197 -5(14))° = (197 -70)°
m∠x = 127°
The following data points represent the number of points scored last basketball game by each player on the Dragons basketball team.
5,8,11,7,?
If the mean of the data set is 8 points, find the missing number of points.
Answer:
9
Step-by-step explanation:
There are 5 data points. To find the mean, we add the data and divide by 5
(5+8+11+7+?) /5 = 8
Multiply each side by 5
(5+8+11+7+?) /5 *5 = 8*5
(5+8+11+7+?) = 40
Combine like terms
? + 31 = 40
Subtract 31 from each side
? +31-31 = 40-31
? = 9
The missing number is 9
The coefficient of 8.2 N is
8
2
16
Answer:
2
Step-by-step explanation:
A coefficient is the number placed before the variable. The variable gets multiplied by the coefficient.
The format is not exactly clear with the expression in the question.
Assuming the expression is '8 * 2n', the coefficient would be 2.
'n' is getting multiplied by '2'.
'8' does not have a variable next to it, so it is just a term in the expression.
The product of 8 and 2 is 16. 16 is not in the expression.
If the expression was '8.2n', 8.2 would be the coefficient.

Which scatterplot shows the strongest negative linear association? On a graph, points are grouped closely together and increase. On a graph, points are grouped closely together to form a line and increase. On a graph, points are grouped closely together and decrease. On a graph, points are grouped closely together to form a line and decrease.
On a graph, points are grouped closely together to form a line and decrease.
====================================
Explanation:
Negative association is where the points decrease as you move from left to right. In other words, you move downhill as you move from left to right. There could be random upward bumps here and there, but overall the general trend is down.
Linear association is when the points are close to the same straight line, known as the regression line.
When points have strong negative linear association, we combine the two ideas mentioned above. The points are close to the same straight line and this line has a negative slope. The correlation coefficient r is close to r = -1.
Choice C is a close answer, but choice D is the better answer due to the "to form a line". If all points are on the same straight line, then r = -1 exactly and we have the strongest possible negative correlation.
The strongest negative linear association is depicted by the graph where points are grouped closely together to form a line and decrease.
Linear associations are deduced from a graph when the points are grouped closely together to form a line. Then we have a strong linear association. Negative association are deduced from a graph when the slope of the line decreasesTherefore, a graph with closely grouped points which forms a line and decreases infers a strong negative linear association.

PLease answer !!! Find constants $A$ and $B$ such that \[\frac{x + 7}{x^2 - x - 2} = \frac{A}{x - 2} + \frac{B}{x + 1}\] for all $x$ such that $x\neq -1$ and $x\neq 2$. Give your answer as the ordered pair $(A,B)$. and Find all values of $t$ such that $\lfloor t\rfloor = 2t + 3$. If you find more than one value, then list the values you find in increasing order, separated by commas.
Answer:
1. [tex](A,B) = (3,-2)[/tex]
2. The values of t are: -3, -1
Step-by-step explanation:
Given
[tex]\frac{x + 7}{x^2 - x - 2} = \frac{A}{x - 2} + \frac{B}{x + 1}[/tex]
[tex]|t| = 2t + 3[/tex]
Required
Solve for the unknown
Solving [tex]\frac{x + 7}{x^2 - x - 2} = \frac{A}{x - 2} + \frac{B}{x + 1}[/tex]
Take LCM
[tex]\frac{x + 7}{x^2 - x - 2} = \frac{A(x+1) + B(x-2)}{(x - 2)(x-1)}[/tex]
Expand the denominator
[tex]\frac{x + 7}{x^2 - x - 2} = \frac{A(x+1) + B(x-2)}{x^2 - 2x + x -2}[/tex]
[tex]\frac{x + 7}{x^2 - x - 2} = \frac{A(x+1) + B(x-2)}{x^2 - x -2}[/tex]
Both denominators are equal; So, they can cancel out
[tex]x + 7 = A(x+1) + B(x-2)[/tex]
Expand the expression on the right hand side
[tex]x + 7 = Ax + A + Bx - 2B[/tex]
Collect and Group Like Terms
[tex]x + 7 = (Ax + Bx) + (A - 2B)[/tex]
[tex]x + 7 = (A + B)x + (A - 2B)[/tex]
By Direct comparison of the left hand side with the right hand side
[tex](A + B)x = x[/tex]
[tex]A - 2B = 7[/tex]
Divide both sides by x in [tex](A + B)x = x[/tex]
[tex]A + B = 1[/tex]
Make A the subject of formula
[tex]A = 1 - B[/tex]
Substitute 1 - B for A in [tex]A - 2B = 7[/tex]
[tex]1 - B - 2B = 7[/tex]
[tex]1 - 3B = 7[/tex]
Subtract 1 from both sides
[tex]1 - 1 - 3B = 7 - 1[/tex]
[tex]-3B = 6[/tex]
Divide both sides by -3
[tex]B = -2[/tex]
Substitute -2 for B in [tex]A = 1 - B[/tex]
[tex]A = 1 - (-2)[/tex]
[tex]A = 1 + 2[/tex]
[tex]A = 3[/tex]
Hence;
[tex](A,B) = (3,-2)[/tex]
Solving [tex]|t| = 2t + 3[/tex]
Because we're dealing with an absolute function; the possible expressions that can be derived from the above expression are;
[tex]t = 2t + 3[/tex] and [tex]-t = 2t + 3[/tex]
Solving [tex]t = 2t + 3[/tex]
Make t the subject of formula
[tex]t - 2t = 3[/tex]
[tex]-t = 3[/tex]
Multiply both sides by -1
[tex]t = -3[/tex]
Solving [tex]-t = 2t + 3[/tex]
Make t the subject of formula
[tex]-t - 2t = 3[/tex]
[tex]-3t = 3[/tex]
Divide both sides by -3
[tex]t = -1[/tex]
Hence, the values of t are: -3, -1

Answer:
$86.81
Step-by-step explanation:
Using the given formula, we want to compute A for ...
P = 4750
r = 0.2279
n = 365 . . . . . assuming "exact" interest
t = 1 or 30
For 1 day late:
A = 4750(1 +0.2279/365)^(365·(1/365)) = 4752.97
For 30 days late:
A = 4750(1 +0.2279/365)^(365·(30/365)) = 4839.78
The difference in these payment amounts is ...
$4839.78 -4752.97 = $86.81
You would save $86.81 in interest charges by paying only 1 day late.
