What is the value of x?
Answer:
x = 4[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
x = 4[tex]\sqrt{3}[/tex]

Which of the following expresses the possible number of positive real
solutions for the polynomial equation shown below?
5x3 + x2 + 7x – 28 = 0
A. One
B. Two or zero
C. Two
D. Three or one
Answer:
A. OneStep-by-step explanation:
Look at the last term, - 28.
It means, the product of roots is a positive number (28).
The polynomial is a degree three so it has 3 possible roots.
Positive product can be obtained if all 3 numbers are positive or 2 negative and 1 positive.
Therefore number of positive roots is one or three.
Further, double check using the graphical solution (see attached), it shows one root only. It means the other roots are complex.
Correct option is A

Mackenzie is deciding between two parking garages. Garage A charges an initial fee of $12 to park plus $5 per hour. Garage B charges an initial fee of $6 to park plus $6 per hour. Let A represent the amount Garage A would charge if Mackenzie parks fort hours, and let B represent the amount Garage B would charge if Mackenzie parks for t hours. Write an equation for each situation, in terms of t, and determine the hours parked, t, that would make the cost of each garage the same
Answer:
A=5t+12
B=6t+6
At 6 hours, both equations equal $42.

Jessie's mom gave her some money to go shopping. She has $100 to spend on new shirts at the store. The store Jessie chooses is having a sale; all shirts cost $10. The function T(s)=10s represents the total cost of the shirts, where s is the number of shirts purchased. What is the domain of T(s) in this context?
Question 9 options:
all non-negative integers that are multiples of 10
all whole numbers
all non-negative rational numbers
all non-negative integers less than or equal to 10
Answer:
T(s)'s domain is A
Hope This Helps!!!
Answer:
d
Step-by-step explanation:
the shirts are only 10 dollars so that means that the domain is all negative numbers that are either equal to or less than 10, not the multiples.

Answer:
Positive
Step-by-step explanation:
It is going up from left to right
Hope this helps
Answer:
Positive.
Step-by-step explanation:
As you go along the x axis and the values of x increase, the values of y also increase. For example, at x = 2 the value of y is 1, and at x = 8 the value of y is 4. This means that the values of y are always increasing as you go up the x axis, so the slope is positive.
You can also tell this from the shape - the line, if read from left to right, is going up, so is positive.

look at the example. how would the quotient change if the total number of seats was 3,200 instead of 320? explain
If the total number of seats is 3200 instead of 320, then the quotient will change by a product of 10
The dividends are given as: 3200 and 320
By comparing 3200 and 320, we have:
3200 > 320 i.e. 3200 is greater than 3203200 = 320 * 10 i.e. 3200 is greater than 320 ten timesQuotient is simply the result gotten from dividing two quantities.
This means that:
If the total number of seats is 3200 instead of 320, then the quotient will change by a product of 10

Sam invests a sum of money into an account that pays 3%

Sam will have doubled his investment for 33 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Sam invests a sum of money into an account that pays 3%
compound interest per annum
We need to find how many years Sam will have doubled his investment.
With C your initial capital, k the interest rate and t the number of years. Since k is given as a simple interest rate, you’re essentially trying to solve :
C(1+tk)=2C
With a little bit of algebra, you should find that:
t=1/k
k=3%=0.03
t=1/0.03=33.33=33 years.
Hence, Sam will have doubled his investment for 33 years.

Answer:
x= 7
B= 112
F= 68
Step-by-step explanation:
to find x we set up an equation, (16x)=(4x+84). They are alternate interior angles which are always equal.
calculate it and you'll find x=7.
B and the angle 4x+84 are equal because they are vertical angles, to find it we just put 7 instead of x into 4x+84.
4(7)+84=112
angle f is supplementary to 16x. 16x is also 112 because they are equal, so its just 180-112=68

Answer:
750 mg
Step-by-step explanation:
if that was 75% of the dose, or 3/4.
We do 600 * (1 - 3/4) = 600 * 1/4 = 150

Answer:
Second choice.
Step-by-step explanation:
Option 1: solve the inequality. Add 7 to both sides, and multiply by -3 (don't forget that this makes the inequality switch direction!) to get [tex]x > {27 \over {-3}[/tex] or x > -9
Option 2. Plug 0 in it. You get -7 < 20, which is obviously true. So 0 is in the set of solution and it means B and C are possible solutions. So let's check another easy value. let's say -10. replacing it you get [tex]-3 (-10) -7 < 20[/tex] or [tex]30 -7 <20[/tex]. But 23 is obviously greater than 20, which means -10 is not a part of the solution. Correct answer is B

The sum of the measure of angle ∠AXY and angle ∠YXB is the measure of ∠AXB.
The relationship between ∠AXY and ∠YXB is that they are;
Complementary anglesReasons:
From the diagram in the question, we have;
∠BXC = 90° Given
∠BXC and ∠BXA are linear pair angles
Therefore;
∠BXC and ∠BXA are supplementary angles, which gives;
∠BXC + ∠BXA = 180° definition of supplementary angles
Therefore;
∠BXA = 180° - ∠BXC
∠BXA = 180° - 90° = 90°
∠BXA = 90°
∠AXY + ∠YXB = ∠BXA by angle addition property
Which gives;
∠AXY + ∠YXB = 90° by substitution propertyTherefore ∠AXY and ∠YXB are;
