Answer:

+ 25

Step-by-step explanation:

b² + 10b

using the method of completing the square

add ( half the coefficient of the b- term)²

b² + 2(5)b + 25

= (b + 5)² ← a perfect square

SpyIntel [72]

Answer:

y = 25

Step-by-step explanation:

Given y = kx and k = 5 then

y = 5x ← equation of variation

When x = 5 , then

y = 5 × 5 = 25

What’s the correct answer for this question?

erma4kov [3.2K]

Answer:

A.

Step-by-step explanation:

Perpendicular => so it will have a slope of negative reciprocal to this slope

Slope = 2/3

Now

Point = (x,y) = (6,5)

So,

x = 6, y = 5

Substituting in the slope intercept form

5 = (2/3)(6)+b

5 = 4+b

=> b = 1

So, we have

m = 2/3

b = 1

Putting in the slope intercept equation

y = 2/3x+1

Which is the closest to the value of x?

alina1380 [7]

<u>Answer:</u>

17.9

<u>Step-by-step explanation:</u>

Here we are given a right angled triangle with a known angle of 72°, length of the perpendicular to be 17 feet and we are to find the length of the hypotenuse x.

For that, we can use the formula for sin for which we need an angle and the lengths of base and hypotenuse.

$sin \alpha =\frac{perpendicular}{x}$

So putting in the given values to get:

$sin 72=\frac{17}{x}$

$x=\frac{17}{sin 72}$

$x=17.8$

Therefore, the length of six cars is the closest to 17.9.
