Answer:
$600
Step-by-step explanation:
2500+625+625+2500=6,250
625/6,250=.10 or 10%
6000x.10=600
Which is the correct expansion of (3x+2)(3x^2+4)
Answer:6x + 3x^2 +4
depending on what your on
Step-by-step explanation:
Answer:
9x^3 + 6x ^2 + 12x + 8
Step-by-step explanation:
Do each individually.
First (3x^2)(3x) = 9x^3
Then (3x^2)(2) = 6x^2
Then (3x)(4) = 12x
Then (4)(2) = 8
Finally add everything together, since everything has a different exponent, then just combine like I have above.
Solve for x
-6/5x-4=-46
Answer:
x = 35
Step-by-step explanation:
-6/5x-4=-46
Add 4 to each side
-6/5x-4+4=-46+4
-6/5x=-42
Multiply each side by -5/6 to isolate x
-5/6 * -6/5x=-42 * -5/6
x = 35
Answer:
x = 35
Step-by-step explanation:
-6 / 5x - 4 = - 46
Add 4 to each side
- 6 / 5 x - 4 + 4 = - 46 + 4
- 6 / 5 x = - 42
To find x, multiply 42 by 5 and then divide by 6.
x = 42 × 5 / 6
x = 7 × 5
x = 35
differentiate between interest and interest rate
Answer:
Interest:Interest is the cost of borrowing money, and the money you earn from your savings.
Interest rateInterest rates indicate this cost or return as a percentage of the amount you are borrowing or lending (since you are “lending” your savings to the bank)

Solve 17 and 18 please.
Answer:
Step-by-step explanation:
17.
sin20° = [tex]\frac{1}{x}[/tex]
x = 1 ÷ sin20°
x ≈ 2.9238
cos20° = [tex]\frac{x}{y}[/tex]
y = x ÷ cos20°
y ≈ 2.9238 ÷ cos20° ≈ 3.11
18.
x = 2√3 ≈ 3.46
y = √3 ≈ 1.732

Answer:
Angle A = 19
Step-by-step explanation:
Vertical angles are congruent ( equal to each other )
If angle A and angle B are vertical angles and vertical angles are congruent then angle A = angle B
If angle A = 3x + 13 and angle B = 5x + 9 then 3x + 13 = 5x + 9
( Note that we just created an equation that we can use to solve for x )
We now solve for x using the equation created
3x + 13 = 5x + 9
Step 1 subtract 3x from both sides
Outcome: 13 = 2x + 9
Step 2 subtract 9 from both sides
Outcome: 4 = 2x
Step 3 divide both sides by 2
Outcome: x = 2
Now to find Angle A
All we have to do to find the measure of angle a is simply substitute 2 for x in it's given expression ( 3x + 13 )
Substitute 2 for x
Angle A = 3(2) + 13
Multiply
Angle A = 6 + 13
Add
Angle a = 19
Find the measure of X
Answer:
7
Step-by-step explanation:
135 = 15*(x+2)
Answer:
x = 7
Step-by-step explanation:
The angles are alternate exterior angles and alternate exterior angles are equal for parallel lines
135 = 15(x+2)
Divide by 15
135/15 = 15/15(x+2)
9 = x+2
Subtract 2
9-2 = x+2-2
x = 7

Explain two procedures that you can use to draw two adjacent complementary angles. Then draw a pair of adjacent complementary angles so that one angle has a measure of 30°.
Answer:
Complementary angle of 30° is 60°.
Step-by-step explanation:
The complementary angles are the angles whose sum is 90.
If one angle is x then the other angle is 90 - x, they both are complementary to each other.
One angle is 30°, so the other angle is 90° - 30° = 60°
Please help and thank you
a. Label another angle whose measure is 76º.
b. Explain how you know this angle has the same measure.

Angle QRS
Step-by-step explanation:
because PQ is parallel to RS, angles PQR and QRS are alternate interior angles so theyre equal
I am leaning pre-cal right now and I don't understand it. I did arctan (3/-5) but got it wrong, how do you do this?
9514 1404 393
Answer:
149.04°
Step-by-step explanation:
You must consider the signs of the components of the vector. The value -5+3i will be in the 2nd quadrant of the complex plane.
When you use the single-argument arctan function, it will tell you the angle is -30.96°, a 4th-quadrant angle. (arctan( ) is only capable of giving you 1st- or 4th-quadrant angles.)
You find the 2nd-quadrant angle by adding 180° to this value:
-30.96° +180° = 149.04° = arg(-5+3i)
__
The attachments show the calculation using a suitable calculator (1st) and a spreadsheet (2nd). The spreadsheet function ATAN2(x,y) gives the 4-quadrant angle in radians, considering the signs of the two arguments. Here, we converted it to degrees. The calculator can be set to either degrees or radians.

Explain why the equation
1- x= 5(x - 4) - 6x has no solution.
Answer:
After the distribution of the 5 and the addition of x to both sides, the x variable is cancelled out leaving 1 = - 20.
This statement is false. Hence, no solution
Step-by-step explanation:
1 - x = 5(x - 4) - 6x (Distribute 5)
1 - x = 5x - 20 - 6x (Combine like terms)
1 - x = -x - 20 add x to both sides
1 = - 20 False
Rewrite the following quadratic function in vertex form. Then, determine if it has a maximum or minimum and say what that value is.
y = -x 2 + 6x + 5
HELP PLEASE!!!!!!
Answer:
-(x-3)²+14
maximum
(3,14)
Step-by-step explanation:
y= -x²+6x+5
y-5= -x²+6x
y-5= -(x²-6x)
complete the square
y-14= -(x²-6x+9)
x²-6x-9= -(x-3)²
y-14= -(x-3)²
y= -(x-3)²+14
maximum because a is negative
vertex is (3,14)
13. Jimmy is writing a paper for one of his classes. The paper has to be 3,000 words
long, and so far he has written 696 words. If he only has 6 more days to write
his paper and wants to write the same number of words each day, then how
many words must he write per day to finish the paper?
Answer:
384 words per day
Step-by-step explanation:
If he already wrote 696 words out of 3,000 words, then he has another 2,304 words left to write. To know how many words he needs to write each day for the next 6 days, then we need to divide 2,304 words by 6. The quotient thus becomes 384 words.
Answer:
384 words per day
Step-by-step explanation:
3000-696=2304
So 2304 divided by 6 =348
and angle is 21 more than twice its complement find it
Answer:
angle = 67°
Step-by-step explanation:
let
a = angle in degrees
(90-a) = complement
given
a = 2(90-a)+21
Solve for a
a = 180 - 2a + 21
3a = 201
a = 67°
Which of the following functions represent exponential decay and has a y-
intercept of 2?
O y = {(0.85)*
O y = (2)*+2
O y = 4 (2)*
O y = 2(3)*
Answer:
Non of the given options
A function that represent an exponential decay and 2 as the y-intercept is y = 0.85ˣ + 1
Step-by-step explanation:
An exponential decay function is a function that reduces in magnitude at a constant percentage rate, r (< 1)
An exponential decay can be represented by the formula, y = a·(1 - r)ˣ
Therefore, the growth factor, (1 - r) = b is less than 1 for an exponential decay
Therefore the function that represent an exponential decay is y = 0.85ˣ, while a function that represent an exponential decay and has a y-intercept of 2 is y = 0.85ˣ + 1. therefore, non of the options
