When there is a negative in front of the exponent it makes a fraction. It is usually just 1/the number it equals if it were positive.
Answer:
[tex] \frac{1}{81} [/tex]
Step-by-step explanation:
express that with a positive exponent using this:
[tex] {a}^{ - n} \frac{1}{ {a}^{n} } [/tex]
so ..
[tex] {9}^{ - 2} = \frac{1}{ {9}^{2} } [/tex]
now you have to evaluate the exponent/ power
so..
[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]
why 81 ?
because the exponent of 9 is 2 so you have to multiple 9 by itself so
9x9=81
so the answer is
[tex] \frac{1}{ {81}^{} } [/tex]
sorry for the bad english hehe

If B = 1 - 2s^2 – s and C = 3 + 5s², find an expression that equals 3B + C in
standard form.
Answers
Answer: -s² - 3s + 6
Step-by-step explanation:
b = 1 - 2s² - s
c = 3 + 5s²
Substitute
3b + c
3 (1 - 2s² - s) + 3 + 5s²
3 - 6s² - 3s + 3 + 5s²
Put like terms together
-6s² + 5s² - 3s + 3 + 3
-s² - 3s + 6

Last night, Roberto spent 90 minutes doing homework, infinity symbol hour reading, and 540 seconds making his lunch for the next day. How many more minutes did Roberto spend doing homework than he did reading and making his lunch?
A) 50 minutes
B) 49 minutes

If you steal the points, ill report you (❁*ᵕ*)︻╦╤─
Answers
Answer:
C. 41 minutes
Step-by-step explanation:
First, we have to turn 540 seconds into minutes by dividing it by 60
540 ÷ 60 = 9
So 50 - 9 = 41
So Roberto spent 41 more minutes reading than he did making his lunch

What is the additive inverse of -10?
Answers
Answer:
The inverse with respect to addition; the opposite. The additive inverse of 12 is −12. The definition of an additive inverse is the number needed to bring a negative number to zero. An example of an additive inverse is the number 30 when added to -30. So the additive inverse of -10 is 10
Step-by-step explanation:
Answer: 10
Step-by-step explanation:
To find the additive inverse of a number, all we should do is change its sign. Thus, the additive inverse of a positive number is a negative number, and the additive inverse of a negative number is a positive one. So the additive inverse of -10, which is negative, is positive 10, or just 10.
The circle below has a radius of 3 units . Find the area of the circle. Use 3.14 for π.
A=πr2=π×r×r
i well give u 10 points
Answers
Answer:
28.26 units
Step-by-step explanation:
We know the radius of the circle is 3 units, so we'll end up plugging that into the formula.
A = π(3^2) or A = π * 3 * 3
When you substitute pi for 3.14, you'll end up getting 28.26 units.

Which triangle is similar to △ABC if sin(A) = One-fourth, cos(A) = StartFraction StartRoot 15 EndRoot Over 4 EndFraction, and tan(A) = StartFraction 1 Over StartRoot 15 EndRoot EndFraction?
Answers
Answer:
ΔXYZ
Step-by-step explanation:
Trigonometric identities are equations which are true for right angled triangles. They are:
sin(A) = opposite / hypotenuse, cos(A) = adjacent / hypotenuse, tan(A) = opposite / adjacent.
Given triangle ABC with ∠A with side BC opposite to the angle, ∠B with side AC opposite to the angle, ∠C with side AB opposite to the angle.
sin(A) = opposite / hypotenuse = BC / AC = 1/4
BC = 1, AC = 4
cos(A) = adjacent / hypotenuse = AB / AC = √15 / 4
AB = √15
tan(A) = opposite / adjacent = BC / AB = 1 / √15
Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion.
ΔXYZ and ΔABC are similar because the ratio of their corresponding sides are in the same proportion.
For adjacent side; XZ / AB = 6√15 / √15 = 6
For opposite side; YZ / BC = 6/1 = 6
For hypotenuse side; XY / AC = 24 / 4 = 6

What is a true statement about making a purchase ? A-if you purchase an item with credit card, the money to pay for your purchase will be loaned to you B- if you purchase an item with a debit card,you may have to pay interest C-If u purchase an item with a credit card, the money will be deducted from your account D-if you purchase an item with debit card, you will have to pay back the bank for the amount you borrowed.
Answers
Answer:
A- If you purchase an item with a credit card, the money to pay for your purchase will be loaned to you
Step-by-step explanation:
The answer is A because when you use a credit card, any money you spend with it is actually being loaned to you, which you will have to pay back at a later date.
The answer is NOT b because when you are using a debit card, you are using your money that you already own, so you don't have to pay interest on anything.
The answer is NOT c because when you buy stuff with a credit card, the money is being loaned to you, not deducted from your account.
The answer is NOT d because you do not have to pay back a loan with a debit card, that's only with credit cards.
