Answer:
a) 36°
b) 37°
Step-by-step explanation:
a) x=14 y=10
tan(0) = 10/14
0 = tan-1 (10/14)
0 = 36
b) x=17 y=13
tan(0) = 13/17
0 = tan-1 (13/17)
0 = 37

Which of the following is a factor of the expression 24x^2-30x-9?
Group of answer choices
12x+1
4x-3
2x+3
4x+1
Answer:
4x + 1
Step-by-step explanation:
24x² - 30x - 9 ( factor out 3 from each term )
= 3(8x² - 10x - 3) ← factor the quadratic
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 8 × - 3 = - 24 and sum = - 10
the factors are + 2 and - 12
use these factors to split the x- term
8x² + 2x - 12x - 3 ( factor the first/second and third/fourth terms )
= 2x(4x + 1) - 3(4x + 1) ← factor out (4x + 1) from each term
= (4x + 1)(2x - 3)
then
24x² - 30x - 9 = 3(4x + 1)(2x - 3) ← in factored form
so (4x + 1) is a factor of the expression

Simplify each algebraic expression by combining like terms.
2x + 5y + 6x - 5x + 3y
x2 + 2x + 3x2 + 4x - 2x2 + x
Answer:
2x^2+7x and 8y+3x
Step-by-step explanation:
Okay for the first one when you combine like terms you are adding the ones with the same terms so the ones that have X in it you add, the one with Y you add so it would be
2x+6x=8x ----> 8x-5x=3x
5y+3y=8y so
8y+3x
same thing for the other one so the answer is:
2x^2+7x

Suppose that 21 inches of wire costs 63 cents.
At the same rate, how much (in cents) will 54 inches of wire cost?
Answer:
162 cents
Step-by-step explanation:
to find the rate you want take the inches which is 21 and divide by the cost which is 63 and find the rate is 3 which means each inch costs 3 cents and so with that rate you can find the cost of 54 inchest of wire so you take your 54 inches and multiply it by 3 which is the cents per inch and find that 54 inches of wire would cost you 162 cents

PROBLEM SOLVING You deposit $300 into an investment account that earns 12% annual interest compounded quarterly. The graph shows the balance of a savings account over time. Write the functions that represent the balances of the accounts after t years. Round the growth factor to the nearest hundredth, if necessary.
Answer:
=25
Step-by-step explanation
:[tex]\sqrt{x}[/tex] 300 with 12 and you simply get 25
The function that represents the balance after t years is FV = $300( 4)^4t. The balance of the account after four years is; $914.92.
What is the function that represents the balance after t years?The formula for calculating future value:
FV = P (1 + r)^nm
Where: FV = Future value
P = Present value
R = interest rate = 12%/4 = 3%
m = number of compounding = 4
N = number of years
Thus FV = $300( 1+ 3)^4t
FV = $300( 4)^4t
Then the account balance after 4 years;
$300( 4)^(4 x 4)
= $914.92

Answer:
D
Step-by-step explanation:
First of, let's make a table for y = cos(x)
(x , y): (0 , 1) (π/2 , 0) (π , -1) (3π/2 , 0) (2π , 1)
Now, making a table for y = 2cos(x) is simple. We just have to multiply all the y-values from the previous table by 2.
(x , y): (0 , 2) (π/2 , 0) (π , -2) (3π/2 , 0) (2π , 2)
Graphing these coordinates, we find that the answer is D.

What is the sum of 10 of the interior angles of a regular dodecagon?
Answer: 1500
Step-by-step explanation:
180° x (12-2) = 180° x 10
= 1800°
(got 12 because a regular dodecagon has 12 congruent sides.)
1800°/ 12 =150
150° x 10= 1500°

Cleo bought a computer for $1,495. What will it be worth after depreciating for 3 years at
a rate of 16% per year?
After 3 years of depreciation at a rate of 16% per year, the computer will be worth $886.93.
To determine the value of Cleo's computer after depreciating for 3 years at a rate of 16% per year, we need to calculate the depreciation amount for each year and subtract it from the original value.
First, let's calculate the depreciation for one year. The depreciation amount is obtained by multiplying the original value by the depreciation rate: $1,495 * 0.16 = $239.20.
After the first year, the value of the computer would be $1,495 - $239.20 = $1,255.80.
Now, we need to repeat this process for the next two years. For the second year, the depreciation amount would be $1,255.80 * 0.16 = $200.93. Subtracting this from the value after the first year gives us $1,055.87.
For the third year, the depreciation amount would be $1,055.87 * 0.16 = $168.94. Subtracting this from the value after the second year gives us $886.93.
