Answer:
x=18
Step-by-step explanation:
We'll assume that the shorter sides are AB and CD. Then 7x-6=5x+30. You add 6 to both sides. 7x=5x+36. Isolate x. 2x=36. Divide, and x=18.

For f(x) = x2 and g(x) = (x - 5)2, in which direction and by how many units should f(x) be shifted to obtain g(x)? (5 points)
O Right 5 units
Up 5 units
Left 5 units
Down 5 units
Answer:
right 5 units
Step-by-step explanation:
given f(x) then f(x ± a) is a horizontal translation of f(x)
• if + a then a shift of a units left
• if - a then a shift of 5 units right
f(x) → g(x) = (x - 5)² with a = - 5
then f(x) is shifted 5 units right to obtain g(x)

The sum of two
numbers is 152 and
their difference is 40.
Find the two numbers.
Answer: The numbers are 96 and 56
Step-by-step explanation:
x+y=152
x-y=40
If you subtract the equations from one another, you will get
x+y=152
-(x-y)=40
So, 2y=112, making y=56
If you plug y=56 into x+y=152, you will get x=96

What speed will a fan turn if the drive motor is turning at 1250 RPM, the motor pulley is 4 inches in diameter, and the fan pulley is 8 inches in diameter
The speed the fan will turn is 625 rpm
Linear speedSince they fan and the pulley ahve the same linear speed v = rω where
r = radius of pulley and ω = angular speed.Then
r₁ω₁ = r₂ω₂ where
r₁ = radius of fan pulley = 8 in/2 = 4 in, ω₁ = angular speed of fan pulley, r₂ = radius of motor pulley = 4 in/2 = 2 in, ω₂ = angular speed of motor pulley = 1250 rpm Angular speed of fan pulleyMaking ω₁ subject of the formula, we have
ω₁ = r₂ω₂/r₁
Substituting the values of the variables into the equation, we have
ω₁ = r₂ω₂/r₁
ω₁ = 2 in × 1250 rpm/4 in
ω₁ = 1250 rpm/2
ω₁ = 625 rpm
So, the speed the fan will turn is 625 rpm

The value of a and b for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.
What is logarithmic regression?Logarithmic regression is a type of regression which is used to model the statement in which the growth or decay initially at rapid rate, and then slow down with respect to time.
The data of the table for the day and height of the stalk of corn is listed below.
Day (x) 9 12 22 40
Height (y) in 5 17 45 60

Mean of y values,
[tex]m_y=\dfrac{5+17+45+60}{4}\\m_y=31.75[/tex]
For the above table, the value of correlation coefficient is 0.99133. For these values, the logarithmic regression can be given as,
[tex]y = -76.2038+37.6735\ln(x)[/tex]
Compare it with the following logarithmic regression equation, we get
[tex]y = a+b\ln(x)[/tex]
[tex]a=-76.2038\\b=37.6735[/tex]

Answer:
x = 8
z = 15
y = 118°
Step-by-step explanation:
First, we know that these are similar. That means that if we know which angles correspond to each other, those are equal, and the sides that correspond to each other have a common ratio. I went ahead and rotated PQRS so that it visually aligns with WXYZ -- that image is attached. We can do this because similar shapes must have the same angles, so aligning the angles works here. Using that, we can see that, based on the angles, QR matches up with XY, WZ matches up with PS, and so on.
We can then say that there is a common ratio between the corresponding sides.
WZ/PS = XW/PQ = ZY/RS = 9/6 = 12/x = z/10
9/6 simplifies to 3/2, so we have
3/2 = 12/x
multiply both sides by x to no longer have it as a denominator
3 * x / 2 = 12
multiply both sides by 2 and divide both sides by 3 to isolate x
x = 8
3/2 = z / 10
multiply both sides by 10 to isolate z
z = 15
In the corresponding figures, we can see that y matches up with ∠WXY. Thus, the two angles are equal and y = 118°

eduardo has 4 1/2 yard of rope light. Exactly how many more yard does he need to finish the car's ceiling
Answer:
2 1/6
Step-by-step explanation:
Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.
4 1/2 -> 9/2
6 2/3 -> 20/3
Next, make the denominators the same by multiplying each fraction by the denominator of the other.
9/2 * 3 = 27/6
20/3 * 2 = 40/6
Then you can subtract the numerators because the denominators are the same:
40/6-27/6= 13/6
Then you can convert to a mixed fraction if need be.
Write an equation for the translation of y = 4/x that has the given asymptotes x = 2, y = 2
Show work
According to the given asymptotes, the equation for the translation of the function is:
[tex]y = \frac{4}{x - 2} + 2[/tex]
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.In this problem, the function is:
[tex]y = \frac{4}{x}[/tex]
The vertical and horizontal asymptotes are, respectively, given by: x = 0, y = 0.
To have the desired asymptotes, the function has to be shifted 2 units to the right and 2 units up, hence it is given by:
[tex]y = \frac{4}{x - 2} + 2[/tex]

An equilateral triangle (all 3 sides are the same length) sits on top of a square. They both share the side AB
Answer:
6x +15
Step-by-step explanation:
To solve for the perimeter of the triangle, we need to find the length of each side.
(a +b)² = a² +2ab +b²
Let's factorise the expression for the area of the square:
Area of square
= 4x² +20x +25
= (2x +5)²
Since area of square= side ×side, length of a side of the square is the square root of its area. We are also given that the side of the square is AB.
(AB)²= (2x +5)²
Taking the square root of both sides:
AB= 2x +5
The perimeter is the sum of the lengths of all of its sides.
Perimeter of the triangle
= 3(AB)
= 3(2x +5)
= 6x +15
