Solve the following quadratic equations by completing the square. y^2-14y+48=0

Mathematics

1 answer:

NISA [10]3 years ago

5 0

Answer:

y = 6 or 8

Step-by-step explanation:

1. Subtract the constant:

y^2 -14y = -48

2. Add the square of half the y-coefficient:

y^2 -14y +49 = -48 +49

Write as a square, if you like:

(y -7)^2 = 1

3. Take the square root:

y -7 = ±√1 = ±1

4. Add the opposite of the constant on the left:

y = 7 ±1 = 6 or 8

The solution is y = 6 or y = 8.

Which represents r in terms of A and S?

ladessa [460]

Answer:

$r=\frac{6\sqrt{10AS}}{S\sqrt{\pi }}$

Step-by-step explanation:

Given the formula;

$A=\frac{\pi r^2S}{360}$

We want to solve the given formula for r.

Multiply both sides by $\frac{360}{\pi S}$

$A\times \frac{360}{\pi S}=\frac{\pi r^2S}{360} \times \frac{360}{\pi S}$

$A\times \frac{360}{\pi S}=r^2$

Take square root of both sides

$r=\sqrt{\frac{360A}{\pi S}}$

$r=\frac{\sqrt{360A}}{\sqrt{\pi S}}$

$r=\frac{\sqrt{360A}}{\sqrt{\pi }\sqrt{S}}$

$r=\frac{\sqrt{360A}\times \sqrt{S}}{\sqrt{\pi }\sqrt{S} \times \sqrt{S}}$

$r=\frac{\sqrt{360AS}}{S\sqrt{\pi }}$

$r=\frac{6\sqrt{10AS}}{S\sqrt{\pi }}$

Hi! Would you guys mind anderring this? A submarine is at a depth of 100 feet below sea level. Then it starts to dive at a rate

Vikentia [17]

Answer:

slope (m) = -50 or -50x

Step-by-step Explanation

I'm assuming that the x-axis is divided by 1 minute segments.

The slope is defined as "the change in y-coordinate" divided by "the change in x-coordinate"

Since the y value is decreasing (negative) 50 feet per minute, then it is safe to say that the slope is -50 (feet)/ 1 minute

Therefore... the slope is -50 or -50x depending on the answer the assignment is looking for

Answer:

Equivalent

Step-by-step explanation:

The sets are not equal since computer science is not the same as algebra.

Equal means exactly the same

Equivalent means they have the same number of items in them
