Answer:

99

Step-by-step explanation:

Since the caterpillar crawled through the origin, her movement can be described by a straight line equation modeled with the points (-2.5; -5.5) and (0; 0).

The slope of a linear equation is given by:

m=\frac{y-y_0}{x-x_0}\\m=\frac{-5.5-0}{-2.5-0}\\m=2.2

For x = 45, the value of y is:

y= 2.2x\\y= 2.2*45\\y=99

The value of the y-axis is 99.

What is the graph description for y=-10x
Serga [27]
Y = - 10x has a negative slope, m = -10, and a y-intercept of (0, 0).

The graph includes the following points:

{(-2, 20), (-1, 10), (0, 0), (1, -10), (2, -20)}.

Attached is a screenshot of the graph, where it includes the y-intercept crossing along the point of origin, (0, 0).

Several students were asked to name the kinds of animals they saw in the past week at the park. Determine the ratio that compare
SVETLANKA909090 [29]

Answer:

A. 1:8

Step-by-step explanation:

We have been given that several students were asked to name the kinds of animals they saw in the past week at the park.

Dogs: 8

Cat: 2

Fish: 4

Lizard: 2

We are asked to find the ratio that compares the number of cats seen to the total number of animals seen.

Let us find total number of animal by adding each type of animals as:

\text{Total animals}=8+2+4+2

\text{Total animals}=16

We can see that the students saw 2 cats, so ratio of cats to total animals would be 2:16.

Dividing 2 and 16 by 2, we will get:

\frac{2}{2}:\frac{16}{2}\Rightarrow 1:8

Therefore, the ratio 1:8 compares the number of cats seen to the total number of animals seen and option A is the correct choice.

A sequence of numbers a1, a2, a3, . . . is defined as follows: a1 = 3, a2 = 5, and every term in the sequence after a2 is the pr
Dmitry [639]

Answer:

  (D)  t^4

Step-by-step explanation:

You have defined ...

  a3 = a2·a1

  a4 = a3·(a2·a1) = a3²

  a5 = a4·(a3·a2·a1) = a4² = (a3²)² = a3⁴

Then if a3 = t, a5 = t⁴

VikaD [51]

Answer:

$24.04

Step-by-step explanation:

3 x $16.99 = $50.97

1 x $24.99 = $24.99

$24.99 + $50.97 = $75.96

$100 - $75.96 = $24.04
