Help!!! A student Is given the rectangle and square shown. The student states that the two figures have the same perimeter. Is this still in correct? Explain your reasoning.

(sin²(x) - 1)/cos(x) = -1

-cos²(x)/cos(x) = -1

-cos²(x) = -cos(x)

cos²(x) - cos(x) = 0

cos(x) (cos(x) - 1) = 0

Then it follows that cos(x) = 0 or cos(x) = 1. But if cos(x) = 0, then the original expression on the left side of the equation would be undefined. Then C is the only valid solution.

Answer: you would save 26 dollars per tire if you got the special deal instead of the normal price.

Step-by-step explanation: a pair = 2 (this is what i did i dont know what you learn by but the special deal is still cheaper.)

Answer:

  C.  (x -1)/(x +7)

Step-by-step explanation:

The factor (x +1) in the numerator cancels the same factor in the denominator, leaving the ratio (x -1)/(x +7). This matches choice C.

Additional comment

Even though (x+1)/(x+1) = 1 and can be removed from the expression, the fact that it is undefined at x=-1 means the reduced ratio (x-1)/(x+7) is only a valid representation of the original ratio when x≠-1. The factor (x+1) may be gone, but the domain restriction associated with it remains.

25% = 25% : 100% = 0,25 ← the end

60% = 60% : 100% = 0,6 ← the end

72,1% = 72,1% : 100% = 0,721 ← the end

7% = 7% : 100% = 0,07 ← the end

9,5% = 9,5% : 100% = 0,095 ← the end

Answer:

Set the denom to 0 and solve.

x^2 - 16 = 0 --> x = -4,4

This means the vertical asymptote is 4, -4.

Therefor, the domain is for all real numbers that are not 4, -4.

We ignore the top because if the numerator was 0, it's still a number. But if the denom was 0, then it would be impossible (you can't divide by 0). So for all numbers that can go into the denom that aren't 0, is your domain.

Answer:

[tex]c = 300000 {(1.05)}^{50} [/tex]

Step-by-step explanation:

The future value formula is FV=PV(1+i)^n, where the present value PV increases for each period into the future by a factor of 1 + i.  value PV increases for each period into the future by a factor of 1 + i. 

[tex]fv = pv {(1 + r)}^{n} [/tex]

fv = future value

pv = present value

r = annual interest rate ( decimal number)

n= period

Answer:

c = 6 + 0.39p    or    c = 0.39p + 6

Step-by-step explanation:

p = #pounds

c = total cost to ship

cost c = $6 + $0.39p  ($6 flat fee + $0.39 per pound)

Answer:

C=0.39P+6

Step-by-step explanation:

0.39 is per pound, 6 is the fixed charge

Answer:

1 divided by 8 = 0.125 let's replace the 0 with a 2 since 2 is the whole number = 2.125 is correct

Step-by-step explanation:

Jeremy has mistaken 2 1/8 as 2.18 probably because he thought 1/8 was 0.18

The correct decimal value is 2.13.

We have Jeremy who incorrectly said that [tex]2\frac{1}{8}[/tex] is the same as 2.18.

We have Convert [tex]2\frac{1}{8}[/tex] to a decimal correctly.

The method to convert the mixed fraction to normal fraction is -

[tex]5\frac{2}{3}\\[/tex] = [tex]\frac{3\times 5 +2}{3} = \frac{17}{3}[/tex]

According to question, we have -

Mixed fraction = [tex]2\frac{1}{8}=\frac{17}{8}[/tex] = 2.125 = 2.13

Hence, the correct decimal value is 2.13.

Hi there!

We are given:

[tex]4^{\frac{1}{2}x} = 256[/tex]

We can rearrange this into a logarithm:

Answer:

Step-by-step explanation:

We need to write this equation in y=mx+b where m is the slope.

3y= -2x +9

y= -2/3 +9

So now that it is in the form of y=mx+b, we can find the slope. -2/3 is the slope of the equation. Hope that helps!

Step-by-step explanation:

Answer:

A. y = |x - 5| - 4

Step-by-step explanation:

The shape of the graph is a V with slope 1 on the right side and slope -1 on the left side. The parent function is y = |x|. The vertex of the V in the parent function is at (0, 0). Here, there has been a translation of the vertex to (5, -4).

The x-coordinate shifted 5 units right, or a shift of +5, and the y-coordinate shifted 4 units down, or a shift of -4.

y - k = |x - h| shows a shift of h units in x and k units in y when compared to the parent function y = |x|.

y - (-4) = |x - 5|

y + 4 = |x - 5|

y = |x - 5| - 4

Answer: A. y = |x - 5| - 4
