Solve for b. 13/b = 8/1 A. b=1.25 B. b=1.26 C. b=16.25 D. b=1.625

Sati [7]

Answer: $b=13/8$

Cross multiply

$(13)*(1)=8*b\\13=8b$

Flip the equation

$8b=13$

Divide both sides by 8

$8b/8=13/8\\b=13/8$

What is the range of y = –5sin(x)?

sergejj [24]

Answer:

$-5\leq y\leq5$ is the required range.

Step-by-step explanation:

We have been given a function:

$y=-5sin(x)$

The range of sin x is $-1\leq sinx\leq1$

multiply -5 in each term of the above equation.

$-1(-5)\geq -5sinx\geq-5$

$\Rightarrow 5\geq -5sinx\geq-5$

Hence, the required range is:

$-5\leq -5sinx\leq5$

replace -5sinx by y so, we get:

$-5\leq y\leq5$

Choose the constant term that completes the perfect square trinomial. y2 + y

Oduvanchick [21]

Hello!

First off, please write y2 + y as y^2 + y. The " ^ " symbol denotes exponentiation, whereas y2 is meaningless.

To find the constant term in question, take half of the coefficient of y (that is, take 1/2) and square it. Then we have y2 + y + 1/4.

The constant term in question is 1/4.
