Answer:

1. Yes

2. No

Step-by-step explanation:

Question 1:

The x is going in a constant rate of 1. While the y is going up in the constant rate of 5, so it is linear.

Question 2:

The x is going in a constant rate of 1. While the y is not going in the constant rate, so it is nonlinear.

$\frac{8}{2z}=\frac{15}{60}\ \ \ \ \ |cross\ multiply\\\\2z\cdot15=8\cdot60\\\\30z=480\ \ \ \ |divide\ both\ sides\ by\ 30\\\\\boxed{z=16}$

The vertex of this parabola is at (-5, -2). When the x-value is -4, the y-value is 2. What is the coefficient of the squared exp

VARVARA [1.3K]

V(-5;-2)
$f(x)=a(x+5)^2-2$

$x=-4$ . $y=2$

$2=a(-4+5)^2-2$
$2=a*1-2$
$2=a-2$
$a=4$

The answer: B

A dolphin jumped up out of the water and back into the water in a parabolic path. (H) height (t) seconds . H=-8(t-0.5)^2+2 . How

tigry1 [53]

Answer:

4 seconds

Step-by-step explanation:

using the vertex formula of a quadratic,

$a(x-h)^{2} + k$ , where (h,k) is the vertex

$h = -8(t-0.5)^{2}+2$ h is height and t is time in seconds

the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)

Height of 1/2

time of 2 seconds

it will take 2 additional seconds to reach the water again.

this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.

10 marbles are placed in a bag and two of them are randonly drawn.

Gelneren [198K]

The problem does not say anything about how many of the marbles are yellow but if you put the first one back in the bag then it is an independent probability and each one would be the same individual probability. Since the problem doesn't say and I don't know if you have it somewhere else, I'll do it as an example.

Let's say there were 6 of the 10 marbles were yellow. So the probability of the first one is 6/10 and so is the second one 6/10. To find the total probability you multiply them together 6/10*6/10=36/100=9/25

Hope that helps. If you can tell me how many yellow there are I will show the work for the specific problem.
