If y varies directly as x, and y is 400 when x is rand y is r when x is 4 what is the numeric constant of variation in this rela

s344n2d4d5 [400]

Answer:

Step-by-step explanation:

y = kx

400 = kr . . . . . . (1)

also, r = 4k . . . .(2)

400 = k(4k) = 4k^2

k^2 = 400/4 = 100

k = sqrt(100) = 10

Can someone helpp with thissssssssssssssss

Law Incorporation [45]

Answer:

Step-by-step explanation:

let’s say each side length is called a, b, and c

to find out if a side length is a solution you have to know that

a < b + c

b < a + c

c < a + b

if all of these are true then the given lengths can be the sides of a triangle

ex:

a = 3, b = 4, c = 5

3 < 4+5

3 < 9

this is true

4 < 3+5

4 < 8

this is true

5 < 3+4

5 < 7

this is true

so these side lengths can make a triangle

however, if one of these inequalities weren’t true (ex: 9 < 4) you wouldn’t be able to make a triangle with the given side lengths

Answer:

The grade you make on your exam varies directly with the number of correct answers. The constant of variation is 5

Solution:

Given, The grade you make on your exam varies directly with the number of correct answers you get on the exam.

Answering 15 questions correctly will give you a grade of 75 what is the.

We have to find what is the Constant of variation.

Now, according to the given information, grade  number of correct answer

Then, grade = c x number of correct answers, where c is constant of variation.

Now, substitute grade = 75 and number of correct answers = 15

$\text { Then, } 75=c \times 15 \rightarrow c=\frac{75}{15}=5$

Hence, the constant of variation is 5
