A worker earns 6.25 per hour for how many hours would the worker have to work to earn 400

Answers

Answer 1

Answer: Amount earned in one hour : 6.25

Amount needed to earn : 400

So, number of hours required for earning the required amount :
= Needed amount/Amount earned in an hour
= 400/6.25 = 64

What is the solution to the following bernoulli de?\[t^2 dy/dx+y^2=ty\]
It looks like it is homogenous because if you divide through by \[t^2\] it will be \[y/t\] all over. Also if it's a bernoulli, wouldn't \[v=y\], which isn't very useful. Any thoughts?

Answers

Here t is constant only x and y are variables so it reduces to

dy/ty-y^2 = 1/t^2(dx)

just solve it taking t as constant.

∠A and ∠B are complementary angles of right triangle ABC, cos A = 0.83, and cos B = 0.55. What is sin A sin B?

Answers

Complementary angles are two angles which add up to 90° or forms a right angle. First, we find the value of A and B.

A = arccosine (0.83) = 34°
B = 90 - 34 = 56°

Thus, sin A = 0.56 and sin B = 0.83.

Which represents a quadratic function?f(x) = −8x^3 − 16x^2 − 4x

f (x) = 3/4 x ^2 + 2x − 5

f(x) = 4/x^2 - 2/x + 1

f(x) = 0x^2 − 9x + 7

Answers

A quadratic equation is of the format:

ax² + bx + c = 0, where a ≠ 0.

The first option is not quadratic, it is a cubic, it has highest power of 3.

The second option f (x) = 3/4 x ^2 + 2x − 5, is quadratic, that is the answer.

The third f(x) = 4/x^2 - 2/x + 1, doesn't qualify because of the 2/x.

The last f(x) = 0x^2 − 9x + 7 , doesn't qualify because of the a = 0, and the rule is that a ≠ 0.

Therefore f (x) = 3/4 x ^2 + 2x − 5 represents a quadratic function.

I hope this helps.

Hello,

a quadratic function has y=ax²+bx+c with a!=0 for equation.
Thus the only answer is f(x)=3/4 x²+2x-5
