Which equation is represented by the intersection of the graphs below?<br><br> Image is above.
zaharov [31]

Option B:

sin x = 1 is the equation represented by the intersection of the graph.

Solution:

The graph lies between -1 and 1 in y-axis.

x-axis of the graph is all real numbers.

The graph oscillates between -1 and 1 and a shape that repeats itself every 2π units.

That is the domain of the graph is all real numbers.

The range of the graph is [-1, 1].

It clearly shows that, it is the graph of sinx = 1.

Hence sin x = 1 is the equation represented by the intersection of the graph.

Option B is the correct answer.

A litter of 9 kittens available for adoption at the Humane Society has four orange kittens and five black kittens. A family come
Dovator [93]

Answer:

B

Step-by-step explanation:

What is required is the probability of selecting one orange and one black kitten.

outcomes ( 1 O and 1B) = 4C1 * 5C1

Total outcomes = 9C2

Note: the order of color does not matter it is simply a matter of selection hence only combinations are made NOT permutations.

P (1O and 1B) = outcomes ( 1 O and 1B) / Total outcomes

P (1O and 1B) = (4C1 * 5C4) / 9C2 = 0.5556

Name the property of real numbers illustrated by the equation.
nirvana33 [79]
Answer: Choice A) Distributive property

We're multiplying the outer -3 with the inner x to get -3x
Also, multiply the outer -3 with the inner +4 to get -12

So that's why -3(x+4) = -3x-12

The length of a rectangle is 11 in. longer than its width. The perimeter of the rectangle is 86 in.
GenaCL600 [577]
P = 2(L + W)
P = 86
L = W + 11

86 = 2(W + 11 + W)
86 = 2(2W + 11)
86 = 4W + 22
86 - 22 = 4W
64 = 4W
64/4 = W
16 = W

L = W + 11
L = 16 + 11
L = 27 <====

The position of an object at time t is given by s(t) = -9 - 3t. Find the instantaneous velocity (by using the limit) at t = 8 by
Ede4ka [16]

Answer: v=-3

Step-by-step explanation:

Given

The position of a particle is s(t)=-9-3t

Velocity is given by the derivative of position with respect to time

\Rightarrow v=\dfrac{ds}{dt}\\\Rightarrow v=-3

So, velocity is constant at any point in time.

At t=8, it is v=-3
