38% of what is 152? Show work

marusya05 [52]

Take that certain number we are looking for as 'n'

38% ⇒ 0.38

0.38n = 152

Divide by 0.38

0.38n = 152
/0.38 /0.38

n = 400

So 38% of 400 is 152.

This table lists the coordinates of points on a line. What is the y-intercept of the line?

alexgriva [62]

Answer:

The line intercepts the y-axis and $y = 8$

Step-by-step explanation:

The intersection on the y-axis of a line is found to be $x = 0$ .

That is, the intercept with the y-axis is the value of the function when x is equal to zero.

In this case we know the following points of the function:

x : -2 -1 0 1 2 3

y : 16 12 8 4 0 -4

Note that when $x = 0$ then $y = 8$ .

Therefore the line intercepts the y-axis and $y = 8$

Two vectors A⃗ and B⃗ have magnitude A = 2.93 and B = 3.00. Their vector product is A⃗ ×B⃗ = -4.95k^ + 1.94 i^. What is the angl

Klio2033 [76]

Answer:

Angle is 37.21 degree

Step-by-step explanation:

Given Data

|A|=2.93

|B|=3.00

A×B=-4.95k+1.94i

Angle=?

Solution

|A×B|=|A|×|B|Sinα

First for |A×B|

|A×B|= $\sqrt{x^{2}+y^{2} }$

|A×B|= $\sqrt{(-4.95)^{2}+(1.94)^{2} }$

|A×B|=5.316

|A×B|=|A|×|B|Sinα

Sinα= $\frac{|A*B|}{|A||B|}$

Sinα= $\frac{5.316}{8.79}$

α=37.21 degree
