Answer:
16/21
Step-by-step explanation:
In the first fraction, the negative numerator and negative denominator cancel each other.
In the second fraction, the negative numerator and negative denominator cancel each other.
The equivalent equation is
8/9×6/7=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
8×6/9×7=48/63
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 48 and 63 using
GCF(48,63) = 3
4/8÷43/63÷3=16/21
Therefore:
−8/9× −6/7=16/21

The freefall function to calculate velocity, v, of an object that begins at rest and falls for distance d is v(d) = 2gd , where g is the acceleration due to gravity. The Storm Runner roller coaster at Hershey Park drops 55 m. Use the free-fall function to calculate to the nearest tenth its velocity at the end of the freefall. Use g = 9.8 m/s2 Enter your answer, rounded to the nearest tenth, in the box. v(55) = m/s
9514 1404 393
Answer:
32.8 m/s
Step-by-step explanation:
The function is actually ...
[tex]v(d) = \sqrt{2gd}[/tex]
Filling in the given values, the velocity is about ...
[tex]v(55) = \sqrt{2\cdot9.8\cdot55}=\sqrt{1078}\approx32.8\text{ m/s}[/tex]
The velocity at the end of the free-fall is about 32.8 meters per second.

What function has an inverse function that is well-defined? What process should I go through to determine the original function if all I was given were the inverse function and a table of values for that function?
Answer:
For instance, if the point (1, 3) is on the graph of the function, then the point (3, 1) is on the graph of the inverse. That is, if you start with x = 1, you will go to y = 3; then you plug this into the inverse, and you'll go right back to x = 1, where you started from.

Evaluate the function for x=2 and x=7.
The domain of t(x) = -3.8x– 4.2 is {-3, -1.4, 0, 8} What is the range.
Answer:
-11.8, -30.8, and range is {7.2, 1.12, -4.2, -34.6}
Step-by-step explanation:
t(x)= -3.8x-4.2
Evaluate the function for
x=2 is t(x=2)=-3.8*2-4.2= -11.8
x=7 is t(x=7)=-3.8*7-4.2=-30.8
domain are the values of x and are {-3, -1.4, 0, 8}
the range are the values of y or values of t(x)
t(x=-3)= 11.4 -4.2 =7.2
t(x=-1.4)= 5.32 -4.2 =1.12
t(x=0)= -4.2
t(x=8)= -30.4-4.2= -34.6
so the range is {7.2, 1.12, -4.2, -34.6}

answers are at the bottom
Answer: 1) m=2, 2) m=-2/3, 3) m=-2/5 4) m=-1/2 5) m=4 6) m=1
Step-by-step explanation:
2, 3, & 4 are all declining so they are going to be negative and 1, 5, & 6 are all inclining so they’re positive. When you put the amount you go up vertically from point to point over the amount you travel horizontally between each point you should get the slope for each graph.

Consider the function f(x) = 3x − 2. Select True or False for each statement. The y-intercept is 2. A True B False The x-intercept is 2 3 . A True B False The slope is 3. A True B False
Answer: A false, B true, C true
Step-by-step explanation:
A) intercept with y axis
That means x=0
y= 3*0-2
y= -2 So A is false
B) intercept with x axis
That means y=0
0= 3x-2
2=3x
2/3= x B is true
C) The form of linear function is
f(x)= mx +n, where m is the slope
In this case m= 3 so C is true
1. The y - intercept is 2. ⇒ False
2. The x - intercept is 2/3 ⇒ True.
3. The slope is 3. ⇒ True.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The function is,
f (x) = 3x - 2
Now,
1. To find the y - intercept we substitute x = 0 in the function.
Hence, The y - intercept is,
f (x) = 0 - 2
f (x) = - 2
Hence, The statement y - intercept is 2 is False.
2. To find the x - intercept we substitute f(x) = 0 in the function.
Hence, The y - intercept is,
f (x) = 3x - 2
0 = 3x - 2
3x = 2
x = 2/3.
Hence, The statement x - intercept is 2/3 is True.
3. We know that;
The slope intercept form of the line is,
y = mx + b
Where, m is slope of the line.
And, b is y - intercept.
So, By comparing with the function f (x) = 3x - 2 , we get;
Slope (m) = 3
Hence, The slope is 3 is True.

Can you please help me with these problems, I just don't really understand how to calculate the area of these types of shapes.
thank you!
4. Not enough info, the shape is cut off. Are there 4 sides or 5? If there's a 5th side, is it slanted or parallel to the one labeled 10 ft?
5. The circle has a radius of 7 m, so its area is
π (7 m)² = 49π m²
Subtract from this the area of the white triangle. It has a base length equal to the diameter (i.e. twice the radius) of the circle, and a height equal to the radius, so its area is
1/2 (14 m) (7 m) = 49 m²
So the area of the shaded region is (49π - 49) m², or 49 (π - 1) m².
6. The rectangle has length 14 yd and height equal to the diameter of the circular cutout, 10 yd, so its area is
(14 yd) (10 yd) = 140 yd²
The circular cutout is a semicircle with radius 5 yd, so its area is
1/2 π (5 yd)² = 25π/2 yd²
Then the area of the shaded region is (140 - 25π/2) yd², or 1/2 (280 - 25π) yd².
7. The circle has radius 13 in, so its area is
π (13 in)² = 169π in²
The triangle has height 23 in and length 12 in, so its area is
1/2 (23 in) (12 in) = 138 in²
Then the area of the shaded region is (169π - 138) in².
8. The shaded region is a rectangle with a smaller rectangular cutout. The larger rectangle has height 19 cm and length 18 cm + 16 cm = 34 cm, so its area is
(19 cm) (34 cm) = 646 cm²
The smaller rectangular cutout has length 16 cm and height 19 cm - 16 cm = 3 cm, so its area is
(16 cm) (3 cm) = 48 cm²
Then the area of the shaded region is 646 cm² - 48 cm² = 598 cm².
9. The semicircular piece has radius 3 m, so its area is
1/2 π (3 m)² = 9π/2 m²
The triangle has height equal to the semicircle's diameter, 6 m, and length 9 m, so its area is
1/2 (6 m) (9 m) = 27 m²
Then the area of the shaded region is (9π/2 + 27) m², or 1/2 (9π + 54) m².

If a car uses 5 gallons of gasoline to travel 160 miles, how many gallons would the car use in order to travel 96 miles?
Answer:
3 is your answer.
Step-by-step explanation:
Divide 160 by 5 and you get 32. Multiply it by 3 to get to 96 so it ends up as 3.
Answer:
x = 3
Step-by-step explanation:
To find this, let's use a ratio of gallons of gas to miles the car is able to travel.
160 miles / 5 gallons is equal to 96 miles / x gallons, or 160/5 = 96/x.
Cross multiply to get 160x = (5)(96)
Multiply the 96 by the 5 to get 160x = 480
Divide both sides by 160 to get x = 3.
