I have a 74% in my class and I need a 78% to pass what do I need to get on my final exam?

1 answer:

3 0

So the 74% that you have right now is the other 80% of your grade. So you multiply it by its weight and solve for the other one making it equal to 78%.

(.74)(.8) + (.2)(x) = .78
.592 + (.2)(x) = .78
(.2)(x) = .188
(x) = .94

So, you need to get a 94% on your final test.

Which polynomial function could be represented by the graph below?

kotegsom [21]

Answer:

f(x) = 3(x - 3)^2 - 3

Step-by-step explanation:

Let the base function be

f(x) = ax^2

It has the vertex at (3, -3), so it is translated 3 units right and 3 units down:

f(x) = a(x - 3)^2 - 3

It has zero's at (2, 0) and (4, 0)

Substitute and solve for a:

a(x - 3)^2 - 3 = 0
a(2 - 3)^2 = 3
a = 3

a(4 - 3)^2 - 3 = 0
a = 3

So the function is:

f(x) = 3(x - 3)^2 - 3

-5(p+3/5)=-4 what is the answer

skelet666 [1.2K]

Answer:

-5(p+3/5)=-4 what is the answer

The answer is P = 1/5

Step-by-step explanation:

from the question -5(p+3/5)=-4 applying the law of BODMAS we will use -5 to open the bracket

we have [-5(p) + -5×3/5] = -4

-5p - 3 =-4

collecting the like terms

we have; -5p = -4 + 3

-5p = -1

divide both sides by -5

we have; -5p/-5 = -1/-5

the minus sign cancels out and we have

p= 1/5

check your answer by sloting the value of p into the question -5(p+3/5)=-4

-5(1/5 + 3/5) = -4

-4=-4
