Answer:
192.42 m²
Step-by-step explanation:
big circle
10.5 ² x pi =346.3605
inner circle
7 ² x pi = 153.9380
346.3605 - 153.9380 = 192.4225 (192.42)

Actually Welcome to the concept of expo functions.
f(x) = -8(2)^x - 12 ,
for f(0) ,here substitute x = 0
so we get as ,
==> f(0) = -8(2)^0 -12
==> f(0) = -8-12
==> f(0) = -20
hence, f(0) = -20
Answer:
Step-by-step explanation:
If it went from f(x) ⟹ f(0), that means that x=0.
So, you would plug in 0 for x in f(x)=-8(2)^x-12.
After plugging in the value of x, x=0, into the equation, you should have
f(0)=8(2)^0-12
Now, we are solving for f(0) (or f(x)).
You would use PEMDAS to solve this:
P-PARENTHESIS
E-EXPONENT
M-MULTIPLICATION
D-DIVISION
A-ADDITION
S-SUBTRACTION
There are no parenthesis
there are exponents,
(2)^0 and that =1
so we have f(0)=8(1)-12
there is multiplication, 8(1) which =8
so now we have f(0)=8-12
there is no division
there is subtraction
8-12, which equals -4
f(0)=-4

PLease help me out will give u brainiest
Answer: 252 ft
Step-by-step explanation:
Perimeter is 2(l + w), so when length and width are scaled by 3.5 the new perimeter is 2(3.5l + 3.5w), when factored is 7(l+w). since we are multiplying both sides by 3.5, we multiply 72 by 3.5 to get 252.

A polynomial has zeros x = 2, x = 0, X = 1, X = 2
What is the polynomial in factored form?
A) f(x) = x(x - 2)(x + 1)(x + 2)
B) f(x) = x(x + 2)(x-1)(x + 2)
C) f(x) = x2(x + 2)(x - 1)(x - 2)
D) f(x) = x(x + 2)(x - 1)(x - 2)
Answer:
f(x)= x(x+2)(x-1)(x-2)
Step-by-step explanation:
before taking the zeros each zeros were in the forrm
x+a=0 where 'a' is any number
then after taking the zeros, the zeros were in the form x=0 x=2 x=1
so we are gonna take then back to the form before taking the zeros

The number 55 is multiplied by a 55 digit number that contains only ones. What is the sum of the digits of the product
Answer:
[tex]Sum = 64[/tex]
Step-by-step explanation:
Given
[tex]n = 55[/tex]
[tex]x \to 55\ digit[/tex] 1's
Required
The sum of the [tex]digits[/tex] of the [tex]product[/tex]
To do this, we start with smaller numbers
[tex]55*11 = 605[/tex] ---- 2 digits
[tex]55*111 = 6105[/tex] --- 3 digits
[tex]55*1111 = 61105[/tex] -- 4 digits
[tex]55*11111 = 611105[/tex] -- 5 digits
[tex]55*111111 = 6111105[/tex] --- 6 digits
Notice that as the 1's increase on the left-hand side, the 1's increase on the right-hand side
The difference between the count of both 1's is 2 1's
So, for n digits, we have: 6[n - 2, 1's]05
So, the sum is:
[tex]Sum = 6 + (n - 2) + 0 + 5[/tex]
For 55 digit, [tex]n = 55\\[/tex]
So, we have:
[tex]Sum = 6 + (55 - 2) + 0 + 5[/tex]
[tex]Sum = 6 + 53 + 0 + 5[/tex]
[tex]Sum = 64[/tex]

Answer:
4.5 is the answer to k I've done this before
Answer:
3.5
Step-by-step explanation:
19.5 divided 6.5 is 3. 16.5 divided by 5.5 is also 3. Therefore you must
divide 10.5 by 3 (in order to find K) which leads to 3.5.

A type of fish for your aquarium costs $8 each. You can spend at most $48. How many of these fish can you buy? Write an inequality to model the problem. Then solve the inequality to find the number of fish.
Answer:
x ≤ 6
Step-by-step explanation:
Cost of fish = $8
You can spend at most $48
How many of these fish can you buy?
Let
x = number of fishes you can buy
The inequality is
8x ≤ 48
Divide both sides by 8
x ≤ 48/8
x ≤ 6

The product of two rational number is 7. If one of the number
is 12, Find the other national number
Answer:
7/12 OR 0.58 (2.d.p)
Step-by-step explanation:
Product means that the two rational numbers are being multiplied to get 7.
The question also tells us that one of them is 12. Therefore we can write an equation to express this information where we represent the unknown rational number using the letter 'r':
r x 12 = 7
Rearrange to find r:
r x 12 / 12 = 7 /12
r = 7/12 = 0.5833....
= 0.58 (2.d.p)
Hope this helped!
Answer:
[tex]y = \frac{7}{12}[/tex]
Step-by-step explanation:
x × y = 7
We are given x = 12.
12 × y = 7
Rearrange.
y × 12 = 7
Divide each side by 12.
y × 12 ÷ 12 = 7 ÷ 12
Simplify.
[tex]y = \frac{7}{12}[/tex]
3.) If y vanes inversely as x, and y = 9 when x = 4, find y when x =12
Answer:
y= 36
Step-by-step explanation:
if y varies directly as x, and y=9 when x=4, find y when x=16
.
When you see "direct variation" think:
y = kx
.
To find k, use "y=9 when x=4":
y = kx
9 = k(4)
9/4 = k
.
so, our equation is:
y = (9/4)x
.
now, we can answer:
find y when x=16
y = (9/4)x
y = (9/4)(16)
y = (9)(4)
y = 36
