Answer:
0.6 deg/s²
Step-by-step explanation:
Acceleration is the time rate of change of velocity, it is the ratio of velocity to time. The formula for acceleration is given by:
Acceleration = Change in velocity / time taken = (Final velocity - Initial velocity) / time
Given that the acceleration is 2160 deg/min², we have to convert it to deg/s²
1 min = 60 seconds
1 min² = 60² s² = 3600 s²
[tex]2160\ deg/min^2=\frac{2160\ deg}{1\ min^2*3600\ \frac{s^2}{min^2} }=0.6\ deg/s^2\\ \\2160\ deg/min^2=0.6\ deg/s^2[/tex]
Answer:
0.6

The shape of f(x) = |x|, but shifted 12 units up and then reflected in the x-axis
Answer:
image below
Step-by-step explanation:
Transformation involves changing the position of a function.
The new function is [tex]\mathbf{f"(x) = -|x| - 12}[/tex]
The function is given as:
[tex]\mathbf{f(x) = |x|}[/tex]
When the function is shifted 12 units up,
The rule of transformation is:
[tex]\mathbf{(x,y) \to (x,y+12)}[/tex]
So, the function becomes
[tex]\mathbf{f'(x) = |x| + 12}[/tex]
When the function is reflected in the x-axis,
The rule of transformation is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, the function becomes
[tex]\mathbf{f"(x) = -(|x| + 12)}[/tex]
Expand
[tex]\mathbf{f"(x) = -|x| - 12}[/tex]
Hence, the new function is:
[tex]\mathbf{f"(x) = -|x| - 12}[/tex]
See attachment for the graphs of [tex]\mathbf{f(x) = |x|}[/tex] and [tex]\mathbf{f"(x) = -|x| - 12}[/tex]

A map has a scale of 1cm:20 km two cities are 2.5 cm apart on the map to the nearest tenth of a kilometer what is the actual distance corresponding to the map distance
Answer: 50 km
Step-by-step explanation: So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by
2.5 /1 . Then, 20 x 2.5=50. So the answer is 50 km
The elevation E, in meters, above sea level at which the boiling point of a certain liquid is t degrees Celsius is given by the function shown below. At what elevation is the boiling point 119.5? 120? E(t)= 1200(120-t)+520(120-t)^2 At what elevation is the boiling point 119.5?
E(119.5)= (the answer) meters
Answer:
[tex]E(119.5)= 730m[/tex]
Step-by-step explanation:
Given
[tex]E(t)= 1200(120-t)+520(120-t)^2[/tex]
Required
Determine E(119.5)
[tex]E(t)= 1200(120-t)+520(120-t)^2[/tex]
Simply substitute 119.5 for t
[tex]E(119.5)= 1200(120-119.5)+520(120-119.5)^2[/tex]
Evaluate the expressions in bracket
[tex]E(119.5)= 1200(0.5)+520(0.5)^2[/tex]
Solve 0.5²
[tex]E(119.5)= 1200 * 0.5+520*0.25[/tex]
[tex]E(119.5)= 600+130[/tex]
[tex]E(119.5)= 730[/tex]
Hence;
[tex]E(119.5)= 730m[/tex]
Christopher is designing a rectangular fence to go around his school's chicken coop The length should be 2 ft longer than the width Christopher marks two vertices of the rectangle at Pando in the coordinate plane PO is one of the shorter sides. Each unit in the coordinate plane represents ift Daw rectangle PORS in the coordinate plane to model the fence b. How many feet of long does wed to go around the chicken coop! pls help
Answer:
Christopher needs 24 feet of fencing. Your rectangle should be 5x7 feet.
Step-by-step explanation:
Line PO is 5 feet wide, and we know that the side across from it is 5 feet wide. 5+5=10. The longer sides are supposed to be 2 feet longer than the shorter sides, so they have to be 7 feet long. 7+7=14. 10+14=24.

Twelve decreased by two times a number is 8. Find the number.
Answer:2
Step-by-step explanation: 12-8=4 4/2=2
Answer:
x = 2
Step-by-step explanation:
We can make an equation that meets the requirements stated.
Decreased signifies subtraction, so 12 will reduce the value after it. A number can be any letter you'd like, but I'll stick to x. Since 2 is multiplying that number, we can make 2 the coefficient. Finally, set it equal to 8.
12 - 2x = 8 Subtract 12 from both sides of the equation.
-2x = -4 Divide by -2 on both sides of the equation.
x = 2

which of these is an approximation of 7/9 to the nearest hundred A) 0.078 B) 0.78 C) 1.29 D) 7.8
Answer:
B. 0.78
Step-by-step explanation:
0.78 would be closest to the nearest hundredth, depending on where the decimal is depends on how many numbers that come after the decimal.
Therefore 0.078 would be to the nearest thousandths and 7.8 would be to the nearest tenths.
Answer:
B
Step-by-step explanation:
I recommend simply using a calculator. If you divide 7/9 you would bet 0.7 (repeating). Round to the hundredths and you would get 0.78
Two brothers are painting pictures. One of the
brothers paints 7 pictures in a day. The other
brother paints 8 pictures but it takes him x days
to do so. Together they painted 13 pictures in
x days. The expression above models this
problem. What does represent?
A) The number of days it takes the brothers to
paint 13 pictures
B) The rate at which the two brothers work
together
C) The rate at which the second brother paints
D) The number of days it takes the first brother
to paint 13 pictures
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
Assuming you are asking what does x represent when you say "What does represent" the answer is a: the number of days it take the brothers to paint 13 pictures.
The first 2 sentences are useless and don't tell you anything (well they do but you don't need the information).
Both brothers can paint 13 pictures in x days.
So x means days, more specifically, the number of days it took for the brothers to paint 13 pictures.

solve for x ( need asap )
It is 26 if you needed answer asap
Answer: 26
Step-by-step explanation: the angles are on a straight line and all angles on a straight line add up to 180°, so, you subtract 49 from 180 to get 131 then subtract 1 ( because instead of adding you to subtract to see what was added to get 131) then divide 130 by 5 ( because 5x is the value × 5 ) and you get 26

Help please!!!!! Thank you
Answer:
C
Step-by-step explanation:
So we know that:
[tex]f(3)=-2\text{ and } f(4)=-4[/tex]
This is the same as saying we have two coordinates: (3,-2) and (4,-4).
Let's find the equation of the linear function.
First, let's find the slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute (3,-2) for x₁ and y₁ and let (4,-4) be x₂ and y₂:
[tex]m=\frac{-4--2}{4-3}[/tex]
Simplify:
[tex]m=-2/1=-2[/tex]
So our slope is -2.
Now, use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Let's use (3,-2) for x₁ and y₁ and use -2 for m:
[tex]y+2=-2(x-3)[/tex]
Now, we can figure out the x-intercept.
Recall that the x-intercept is when the graph touches the x-axis.
In other words, the y-value would be 0. It will be (x,0).
So, to solve for the x-intercept, substitute 0 for y and solve for x:
[tex]0+2=-2(x-3)[/tex]
Simplify and distribute the right:
[tex]2=-2x+6[/tex]
Subtract 6:
[tex]-4=-2x[/tex]
Divide both sides by -2:
[tex]x=2[/tex]
So, our x-intercept is (2,0)
a = -bcd
Not sure how I'm suppose to get the answer without dividing first.
Answer:
-1/cd
b = -a/cd
Step-by-step explanation:
a = -bcd
Multiplication and division are inverse operations
Multiply each side by -1/cd
a* -1/cd = -bcd * -1/cd
-a /cd = b

Q1. What is the solution set of 9x-4<13x-7
A. [1,2,3]
B. [1,2,3......]
C. [0,1,2,3...]
D. [0,1,2,3]
Answer:
[tex]\huge\boxed{B. [1,2,3,........]}[/tex]
Step-by-step explanation:
[tex]9x - 4 < 13 x - 7[/tex]
Combining like terms
=> [tex]-4 + 7 < 13x-9x[/tex]
=> [tex]3 < 4x[/tex]
Dividing both sides by 4
=> [tex]x > \frac{3}{4}[/tex]
=> [tex]x > 0.75[/tex]
This means that x can be any number that is greater than 0.75
So, The solution set = [1,2,3,........]
What is 4 1/3 * 2 1/7 as a mixed number in simplest form?
Answer:
9 2/7
Step-by-step explanation:
4 1/3=13/3
2 1/7=15/7
13/3*15/7= 195/21
=9 6/21
=9 2/7
Hi there!
Answer:
9 2/7
Step-by-step explanation:
4 1/3 = 13/3
2 1/7 = 15/7
Now you have to multiply
Which equals to: 195/21
Since this is a improper fraction, you have to divide.
195 divided by 21.
=9 2/7

Complete Question
You are given the dollar value of a product in 2016 and the rate at which the value of the product is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the terms of year t. (Let t=16 represent 2016)
2016 Value Rate
$2150 $250 increase per year
Answer:
The equation is [tex]V(t) = 250 (t) + 4.3[/tex]
Step-by-step explanation:
Generally linear equation is represented mathematically as follows
[tex]y = mx + c[/tex]
Where y is the dependent variable which in this case is dollar value of a product (V(t))
x is the independent variable which in this case is the time in years(t)
m is the slope which in this case is the rate at which the value of the product is expected to change during the next 5 years
So
[tex]V(t) = m t + c[/tex]
When t = 16 years
[tex]2150 = 250 (16) + c[/tex]
=> [tex]c = 4.3[/tex]
So the linear equation is
[tex]V(t) = 250 (t) + 4.3[/tex]
