Answer:

[tex]S \leq 200[/tex]

Step-by-step explanation:

Given

Phone R-Us= $16.95 + $0.05 per SMS

Awesome Wireless = $22.95 + $0.02 per SMS

Required

Determine the number of SMS such that Awesome Wireless is greater or equal to Phone R-Us

Represent the SMS with S

For Phone R-Us, we have:

[tex]SMS = 16.95 + 0.05S[/tex]

For Awesome Wireless, we have:

[tex]SMS = 22.95 + 0.02S[/tex]

For Awesome Wireless is greater or equal to Phone R-Us, we have:

[tex]22.95 + 0.02S \geq 16.95 + 0.05S[/tex]

Collect Like Terms

[tex]0.02S - 0.05S \geq 16.95 - 22.95[/tex]

[tex]-0.03S \geq -6[/tex]

Solve for S

[tex]\frac{-0.03S}{-0.03} \geq \frac{-6}{-0.03}[/tex]

[tex]S \leq 200[/tex]

Hence: for Awesome Wireless to cost more or equal to Phone R-Us, the number of SMS must not exceed 200

The surface area of the rectangular prism is calculated as 340 unit²

The surface area of the prism can be calculated as the sum of surface area of two rectangular prism.

The formula of a rectangular prism is given as;

S.A = 2[(lh + wh + lw)]

Substituting the values into the formula;

S.A = 2[(10*8) + (5 * 8) + (10 * 5)]

S.A = 2[80 + 40 + 50]

S.A = 2 * 170

S.A = 340 unit²

Answer:

f(-3) =  5

f(0) = 8

f(5) = 13

Step-by-step explanation:

Substitute each x-value into f(x)=x+8 to find what each f(x) equals.

Answer:

[tex]\bold{x = \frac{-5 \± i\sqrt7}{2}}[/tex]

Step-by-step explanation:

x^2 + 5x + 8=0

Comparing with ax^2+bx+c=0

we get a = 1, b = 5, and c = 8.

Using the quadratic formula, we have:

[tex]x = \frac{-b \± \sqrt{(b^2- 4ac)}}{ 2a}[/tex]

Substituting these values, we get:

[tex]x =\frac{ -5 \± \sqrt{5^2 - 4*1*8}}{2*1}[/tex]

[tex]x = \frac{-5 \± \sqrt{25 - 32}}{ 2}[/tex]

[tex]x = \frac{-5 \± \sqrt{-7}}{ 2}[/tex]

[tex]x = \frac{-5 \± i\sqrt7}{2}[/tex]

Therefore, the solutions are:[tex]x = \frac{-5 \± i\sqrt7}{2}[/tex]

The equation that represents a line that passes through (-9, -3) with a slope of -6 is D. y+3=-6(x+9). I made a mistake when I was solving it to double-check.

The simplified form of the expression √16 × 16 × √₁ is 64. C.

To simplify the expression √16 × 16 × √₁, let's break it down step by step:

√16 = 4

Taking the square root of 16 gives us 4.

4 × 16 = 64

Multiplying 4 by 16 gives us 64.

√₁ = 1

Taking the square root of 1 gives us 1.

Now we can rewrite the expression with the simplified values:

√16 × 16 × √₁ = 4 × 16 × 1

= 64 × 1

= 64

None of the provided options (a. 4x8, b. 4x4, c. 8x8, d. 8x4) matches the simplified result of 64.

It appears that there might be a typographical error in the options provided.

The correct simplified value is 64, obtained by multiplying 4 and 16 together and disregarding the square root symbols since they have been evaluated.
