Answer:
The "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56. The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.

Secants ⎯⎯⎯⎯⎯⎯⎯⎯⎯ and ⎯⎯⎯⎯⎯⎯⎯⎯⎯ intersect in the exterior of a circle. ∠ measures 27.42° and the measure of DE is 73.18°. Determine the measure of BC.
Answer:
BC = 18.34°
Step-by-step explanation:
Recall: Exterior angle formed by 2 secants = ½(the difference of the measures of the intercepts arcs)
Thus:
m<BAC = ½(DE - BC)
27.42° = ½(73.18 - BC) => Substitution
Multiply both sides by 2
2*27.42 = 73.18 - BC
54.84 = 73.18 - BC
BC = 73.18 - 54.84
BC = 18.34°

Step-by-step explanation:
can someone plz help asap question is in pic (its about graphs)
Answer:
-4,0 and 6.
Step-by-step explanation:
f(x) = 0 is when y = 0.
If you look at the graph, there are 3 instances when y = 0
and it happens when x = -4, x = 0 and x = 6.
Therefore, the solutions of f(x) when y =0 are -4,0 and 6.

If x and y vary inversely and x = 1 when y = 11, find x when y = 5.5.
Answer:
If the variable Y being 5.5 it's because she was divisible by two. So if I divise X by 2 the reply is 0.5. So at least if y is 5.5, x is 0.5.

Notice that the result is a polynomial expression divided by a second polynomial expression. In this section, we will explore quotients of polynomial expressions.
Simplifying Rational Expressions
The quotient of two polynomial expressions is called a rational expression. We can apply the properties of fractions to rational expressions, such as simplifying the expressions by canceling common factors from the numerator and the denominator. To do this, we first need to factor both the numerator and denominator. Let’s start with the rational expression shown.

a
Enter
Answer:
a = [tex]\frac{12}{\sqrt{3} }[/tex]
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{a}{12}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )
a × [tex]\sqrt{3}[/tex] = 12 ( divide both sides by [tex]\sqrt{3}[/tex] )
a = [tex]\frac{12}{\sqrt{3} }[/tex]
Find the total package price from each store and then calculate how much you"lol save if you purchase the less expensive package
Complete Question:
You're planning to buy a new computer, monitor, and printer for your office. You've received the following prices from two stores:
Store 1 Store 2
Computer: 2,500 Computer: 2,350
Monitor: 595 Monitor: 435
Printer: 398 Printer: 349
Find the total package price from each store and then calculate how much you'll save if you purchase the less expensive package.
Answer:
[tex]Total = 3493[/tex] --- Store 1
[tex]Total = 3134[/tex] --- Store 2
[tex]Saved = 359[/tex]
Step-by-step explanation:
From store 1, the total cost is:
[tex]Total = 2500 + 595 + 398[/tex]
[tex]Total = 3493[/tex]
For store 2, the total cost is
[tex]Total = 2350 + 435 + 349[/tex]
[tex]Total = 3134[/tex]
By comparison: It is cheaper to buy from store 2
Because [tex]3134 < 3493[/tex]
Amount saved is calculated by subtracting the cheaper cost from the expensive cost:
i.e.
[tex]Saved = 3493 - 3134[/tex]
[tex]Saved = 359[/tex]

A clothing store charges a 10% tax on each purchase. If a shopper’s total before tax is $63, how much is the tax? Explain how you got your answer
Answer:
To calculate the sales tax that is included in a company's receipts, divide the total amount received (for the items that are subject to sales tax) by "1 + the sales tax rate". In other words, if the sales tax rate is 6%, divide the sales taxable receipts by 1.06.
Caleb and 3 friends are sharing 1/6 quart of milk equally. What fraction of a quart of milk does each of the 4 friends get? Each friend gets blank of a quart of milk.
Answer:
the fraction of quart of milk does each of the four friend get is 1 ÷ 24
Step-by-step explanation:
The computation of the fraction of quart of milk does each of the four friend get is shown below:
= Sharing quart of milk × fraction of friends
= 1 ÷ 6 × 1 ÷ 4
= 1 ÷ 24
Hence, the fraction of quart of milk does each of the four friend get is 1 ÷ 24

Marco is saving money for summer camp. He saves the same amount of money each week. .After 4 weeks, he has saved a total of 60 dollars. After 5 weeks he had saved a total of 75 dollars. Create an equation that represents the only total money. y that Marco had had saved after x weeks.
Answer:
Step-by-step explanation:
(4, 60), (5, 75)
(75 - 60)/(5 - 4)= 15/1 = 15
y - 60 = 15(x - 4)
y - 60 = 15x - 60
y = 15x
Suppose you have a 7-cm by 5-cm rectangle. You increase the length by 1 cm and decrease the width by 1 cm. You continue to do this. What happens to the perimeter of the rectangle? The area? Explain why this happens.
Answer:
Step-by-step explanation:
P of original = 14 + 10 = 24
P of original l + 1 and w - 1 = 16 + 8 = 24
P of original l + 2 and w - 2 = 18 + 6 = 24
The perimeter remains the same each time since Perimeter is to the 1st power and you are summing; by subtracting from one and adding the same amount to another measure there is no change in perimeter
A of original = 7 x 5 = 35
A of original l + 1 and w - 1 = 8 x 4 = 32
A of original l + 2 and w - 2 = 9 x 3 = 27
A of original l + 3 and w - 3 = 10 x 2 = 20
A of original l + 4 and w - 4 = 11 x 1 = 11
The area decreases by 3,5,7,9 units each time since Area is to the 2nd power since you are multiplying two measures, now if you take the 2nd differences of 3,5,7,9 you see that they are 2 units apart each time, so are is squared and the 2nd differences are constant

1) Gary makes $15.00 per hour for a five-day
forty-hour work week. Also, he makes double-
time for holidays. This week, he works three
regular days and two holidays. What will be his
paycheck for this week?
A) $$40
B) $850
C) $860
D) $870
E) $880
Answer:
A) $840
Step-by-step explanation:
15•40 gives us how much money he makes a week normally
divide the result, 600, by 5 to find out how much he makes a day normally which is $120
now that we know how much he normally makes a day we can double $120 to $240 to show how much he makes on holiday days
so he makes $120 normally and $240 on holiday
120•3= 360
240•2= 480
then add
360+ 480= $840
