Remark

That was well worth doing. Desmos gave you the answer to the graph. Unfortunately I can only give you the correct graph. You will have to figure out from the choices which one is the correct answer -- or edit it so I can see what the rest of the question is.

Graph

The red one is f(x) is x + 3 {x <= -2}

The blue one is f(x) is x^2 - 1 {-2 <x <1} Notice the gap at 2. It is not continuous

The green one is f(x) is log_2(-x + 3)  {1 <=x < 3} and there is a gap between the blue and green one.

What is the value of x in the equation 3x - 4y=65, when y=4?<br> N
4vir4ik [10]

Answer:

x =27

Step-by-step explanation:

3x - 4y=65

lets substitute the value of y in the equation:

3x -4(4) =65

3x = 65 +16

3x= 81

x= 81/3

x = 27

A soup can have a volume of 54 π in³ and a height of 6 in.
aniked [119]

Answer:

The area of the label is 36*pi in²

Step-by-step explanation:

A can of soup has a shape of a cylinder, therefore it's volume is equal to:

Volume = pi*r²*h

We need to use the formula above to find the radius of the base, because we need to calculate the lateral area of the cylinder, which is given by:

Lateral area = 2*pi*r*h

Applying the data from the problem we have:

54*pi = pi*r²*6

pi*r²*6 = 54*pi

r² = 54*pi/(pi*6)

r² = 54/6 = 9

r = sqrt(9) = 3 in

Therefore the lateral area is:

lateral area = 2*pi*(3)*(6) = 36*pi in²

If you purchase a DVD player that cost $625 how much sales tax will you pay to the nearest cent if the rate is 7.375%
sergey [27]
We can get the tax pay by multiplying the total cost times the tax rate, and take into account that 7.375% = 7375/100000 that huge denominator comes from adding 100 more zeroes as the decimal places in the tax amount has, so we do have:
(7.375%)(625)
= (<span>7375/100000)(625)
= 46.09
therefore, the 7.375% out of $625 is $46.09</span>
