Two angles are complementary. One angle is ten less than four times the other angle. Find the measure of the larger angle

Nimfa-mama [501]

Answer:

B.70

Step-by-step explanation:

For one or two angles are complementary angle(s), they have to equal 90°.

So, we need to find the larger angle, but what about the other?

Let x be the other angle and y be the angle we are looking for

x + y = 90

Lets look for x first, since one angle is ten less than four times the angle we are looking for or visa versa, we must:

y = 4x - 10

For an exchange, lets take out the y variable for another x variable:

So now we should have x + 4x - 10 = 90

Combine like terms and do cross equation :

x + 4x -10 = 90

5x - 10 = 90

Add 10 to both sides:

5x = 100

100/5 = 20

So x=20

Now for y which is what we are looking for,

y = 4x - 10

Since x is 20, plug it in

y = 80 - 10

y=70 is our larger angle

If $315 is invested at an interest rate of 3% per year and is compounded continuously, how much will the investment be worth in

irina [24]

Answer:

$\$412.64$

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^{rt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

e is the mathematical constant number

we have

$t=9\ years\\ P=\$315\\ r=0.03$

substitute in the formula above

$A=\$315(e)^{0.03*9}=\$412.64$

If f(x) = - 2x2 + 2x - 3, what is f(5)?

Ghella [55]

Answer:

$f(5)= - 43$

Step-by-step explanation:

Numerical Value of Functions

A function can be seen as an equation that has only one value of y for every x inputted. It assigns exactly one output to every input value. Our function is defined by

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

To find f(5) we only need to replace the value of x into the given expression.

$f(5)=- 2(5)^2 + 2(5) - 3$

$f(5)=- 2(25) + 10 - 3$

$f(5)=- 50 + 10 - 3$

$\boxed{f(5)=- 43}$
