The illustration below shows the graph of y as a function of x.
Complete the following sentences based on the graph of the function.
- As x increases, y _______ (increases/decreases).
- The rate of change for y as a function of x is not __________ (constant/constant), therefore the function is ________ (linear/nonlinear).
- For all values of x, the function value y ___ (≤/≥/=) 0.
- The y-intercept of the graph is the function value y = ____.
- When x = 1, the function value y = ___.

Answers

Answer: As "x" increases "y" *decreases*

y as a function of x is not *constant*

Therefore the function is *nonlinear*

For all values of x, the function value y *≥* 0.

The y intercept of the graph is *8*

x=1 function value of y is *5*

The given function is an exponential function and its qualities are explained below.

What is a logarithmic function?

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

As we can observe in the graph.

The illustration below shows the graph of y as a function of x.

Complete the following sentences based on the graph of the function.

- As x increases, y decreases.

- The rate of change for y as a function of x is not constant, therefore the function is nonlinear.

- For all values of x, the function value y > 0.

- The y-intercept of the graph is the function value y = 8.

- When x = 1, the function value y = 5.

In a race, 41 out of the 50 bicyclists finished in less than 38 minutes. What percent of bicyclists finished the race in less than 38 minutes? Write an equivalent fraction to find the percent.

Answers

for left put 2 on each
On the box over 100 put 82, and put 82 in the box on the right

to find the percent, you will double everything because you only have 50 as the base and doubled its 100. 41 times 2 it’s equal to 82 so 82% of the bicyclists finished in less than 38 minutes. As a fraction it would be 41 over 50.

Blue = 5x3

Total=12+9+15

2) total = 72 balls

Ratio=3x:4x:5x

3x+4x+5x=72
x=6

Red balls = 3x6

The line is 180 degrees in total so your equation would be-

write y=-2x^2-20x-52 in vertex form then find the axis of symmetry. show your work!

Answers

Answer:

Simplifying

y = 2x2 + 20x + 52

Reorder the terms:

y = 52 + 20x + 2x2

Solving

y = 52 + 20x + 2x2

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying

y = 52 + 20x + 2x2

Hope it helps =D

It will be Y=50+20x+2x2

Answer: LCD = 72

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/8, 1/12, 7/18

For the denominators (8, 12, 18) the least common multiple (LCM) is 72.

LCM(8, 12, 18)

Therefore, the least common denominator (LCD) is 72.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 9/9 = 9/72

1/12 = 1/12 × 6/6 = 6/72

7/18 = 7/18 × 4/4 = 28/72

find the length of of a 100-yard football field in meters. Use 1 yard = 3 feet
and 1 meters ≈ 3.28 feet round to the nerest tenth.

(≈ means about)

Answers

Answer: 91.46m

Step-by-step explanation: The length of 100 yard football field in meters. From the dimension given, 1 yard = 3 feet Therefore, 100 yard = x feet 1 yard = 3 feet 100 yard = x feet X = (100 × 3) / 1 X = 300 feet. But, 1 meter = 3.28feet X meter = 300 feet X = (300 × 1) 3.28X = 91.46m Therefore, 100 yard football field is equal to 91.46m
