Step-by-step explanation:

Firstly let us write the square of 0 to 10,

0²=0
1²=1
2²=4
3²=9
4²=16
5²=25
6²=36
7²=49
8²=64
9²=81
10²=100

Hence,

49, 64, 81 and 100 are perfect squares from 40 to 100.

$\\ \tt\longmapsto 49=(7)^2$

$\\ \tt\longmapsto 64=(8)^2$

$\\ \tt\longmapsto 81=(9)^2$

100 won't be counted

If (2,0) is a solution of the linear equation 2x+3y=k,then the value of k is

Margarita [4]

Answer:

k = 4

Step-by-step explanation:

Plug in the values of 2 for x and 0 for y, and solve for k.

2x + 3y = k

2(2) + 3(0) = k

4 = k

k = 4

Which of the following illustrates a phase shift?

Natasha_Volkova [10]

Answer:

A. y = -2 - cos(x-π)

Explanation:

The general form of the trig equation is:

y = A sin (Bx + C) + D

where:

A is the amplitude

$\frac{2\pi}{B}$ is the period

$\frac{-C}{B}$ is the phase shift

D is the vertical shift

Now, let's check the choices:

A. y = -2 - cos(x-π)

$\frac{-C}{B} = \frac{\pi}{1} = \pi$

Therefore, the function has a phase shift of π

B. y = 3 cos(4x)

$\frac{-C}{B} = \frac{0}{4} = 0$

Therefore, the function has no phase shift

C. y = tan(2x)

$\frac{-C}{B} = \frac{0}{2} = 0$

Therefore, the function has no phase shift

D. y = 1 + sin(x)

$\frac{-C}{B} = \frac{0}{1} = 0$

Therefore, the function has no phase shift

Based on the above, the correct answer is A

Hope this helps :)

Shelley wants to purchase a cell phone package, which includes a free phone. The cost of the package is $0.10 per minute, for th

GarryVolchara [31]

Answer:

The function would be linear because the rate of change is constant.

Step-by-step explanation:

Given

$Base= \$89.00$

$Rate = \$0.10$ per minute

See attachment for complete question and options

First, we write the function that calculates the cost (C(t)) for t minutes.

This is calculated as:

$Cost = Base + Rate * t$

$C(t) = 89.00 + 0.10 * t$

$C(t) = 89.00 + 0.10t$

Rewrite as:

$C(t) = 0.10t + 89.00$

A function that has the above format is referred to as a linear function which has the general format

$f(x) = mx + b$

Where

m represents the slope/rate and it is constant

From the list of given options, (a) is correct.
