Answer:
y = 10
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{20}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10

if the sum of roots of the quadratic equation x^(2)-3kx-(k+2)=0 is equal to the product of roots,find k
Answer:
1/2
Step-by-step explanation:
quadratic equation is ax²+bx+c=0
Products of roots is c/a
Sum of roots is -b/a
On comparing the above equation with general equation we have
a=1
b=-(3k)
c=-(k+2)
Now it is given that sum of roots and product of roots is equal
So,
-b/a=c/a
-b=c
-[-(3k)]=-(k+2)
3k=-k-2
3k+k=-2
4k=-2
k=-1/2

For all values of x,
f(x) = 2x-3 and g(x) = x²+1
a) Find fg(x)
Simplify and give your answer in the form ax² + b
b) Find gf(x)
Simplify and give your answer in the form ax² + bx+c
Answer:
For f(x) = 2x + 3 and g(x) = -x 2 + 1, find the composite function defined by (f o g)(x)
(f o g)(x) = f(g(x))
= 2 (g(x)) + 3
= 2( -x 2 + 1 ) + 3
= - 2 x 2 + 5 Given f(2) = 3, g(3) = 2, f(3) = 4 and g(2) = 5, evaluate (f o g)(3)

Michael has a new job and earns a salary of $27,000. Jackie has a new job and earns a salary
of $36,000. Michael will receive a salary increase of $3,200 per year, and Jackie will receive a
salary increase of $2,100 per year
Which equation can be used to find x, the number of years it will take Michael to earn the same
salary as Jackie?
A. 27,000x + 3,200x = 36,000x + 2,100x
B. 27,000x + 3,200 = 36,000x + 2,100
C. 27,000x + 3,200x = 36,000x + 2,100
D. 27,000 + 3,200x = 36,000+ 2,100x

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?
Answer:
100 Candy Bars
Step-by-step explanation:
Hey!
==================================================================
Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?
--------------------------------------------------------------------------------------------------------------
We can create an algebraic Equation to solve this.
- We know that Each Candy Bar costs $1.50.
-We multiply the Amount of Candy Bars with the price.
-We know the profit should be $150
⇒ 1.50x = 150
-Divide by 1.50 on both sides
⇒ 1.50x/1.50 = 150/1.50
-Simplify
⇒ x = 100
==================================================================
Hope I Helped, Feel free to ask any questions to clarify :)
Have a great day!

A rectangular prism has a volume of 175 in'. The height of the prism is 7 in. The base is a square. What is the length of a side of the base? please help
Answer:
a=5cm
Step-by-step explanation:
V=B*H
You will get base if you do this:
B=V:H
B=175:7
B=25
I'm not so good with English, side is probably a,so:
Formula for base: B=a²
Then a=√B
a=√25
a=5cm
I hope this helps.
Find the surface area of each figure. Round to the hundredths place when necessary.
Answer:
SA = 997.88 mm²
Step-by-step explanation:
height² = 20.5² - 13.3² = 420.25 - 176.89 = 243.36
height = √243.36 = 15.6
SA = (16 x 13.3) + (16 x 20.5) + (16 x 15.6) + (0.5 x 2 x 13.3 x 15.6)
SA = 212.8 + 328 + 249.6 + 207.48 = 997.88 mm²

Step-by-step explanation:
Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Step 1 find the number of driveways to shovel
25x = $831.25
x = $831.25/25
= 33.25 driveways
Step 2
He can shovel
14 driveways = 8 hours
33.25 driveways = x
Cross Multiply
14x = 8 × 33.25
x = 8 × 33.25/14
x = 19 hours
