What is the area of the shaded region?
(2571 - 48) cm
O (2517 - 30) cm
(2517 - 24) cm
(257-12) cm
Answers
Answer:
Step-by-step explanation:
We are given a circle with a partially shaded region. First, we need to determine the area of the whole circle. To do this, we need the measurement of the radius of the circle:
Use the Pythagorean theorem to solve for the other leg of the right triangle inside the circle:
5^2 = 3^2 + x^2
x = 4
The radius is 4 + 1 cm = 5 cm
So the area of the circle is A = pi*r^2
A = 3.14 * (5)^2
A = 25pi cm^2
To solve for the area of the shaded region:
Ashaded = Acircle - Atriangles
we need to solve for the area of the triangles:
A = 1/2 *b*h
A = 1/2 *6 * 5
A = 15 cm^2
Atriangles = 2 * 15
Atriangles = 30 cm^2
Ashaded = 25pi - 30

Explanation:
VX is a midsegment and it is half as long compared to the parallel side UY. This means UY is twice as long compared to VX
UY = 2*(VX)
s = 2*(s-37)
s = 2s - 74
s-2s = -74
-s = -74
s = 74
This makes UY be 74 units long
So VX = (1/2)*UY = 0.5*74 = 37
Answer:
37
Step-by-step explanation:
The midsegment theorem states that a midsegment is half the measure of the line it is parallel to (the base). So VX is 1/2 of UY. So:
2(s-37)=s
2s-74=s
s=74
VX= 37

What is a formula for the ninth term of the given sequence
Answers
9514 1404 393
Answer:
a9 = -8 +9(9 -1)
Step-by-step explanation:
The given sequence has a common difference of 1-(-8) = 10-1 = 9, and a first term of -8. The formula for the n-th term of such an arithmetic sequence is ...
an = a1 +d(n -1) . . . . . first term a1, common difference d
For the parameter of this sequence, a1=-8 and d=9, the n-th term is ...
an = -8 +9(n -1) . . . . formula for the n-th term
__
Then the formula for the 9th term is ...
a9 = -8 +9(9 -1)
Harriet buys lunch at school every day. She always gets
pizza when it is available. The cafeteria has pizza about 80% of the time.
Harriet runs a simulation to model this using a random
number generator. She assigns these digits to the possible outcomes for each day of the week:
• Let 0 and 1 = no pizza available
• Let 2, 3, 4, 5, 6, 7, 8, and 9 = pizza available
The table shows the results of the simulation.

A. 7/10 = 70%

C. 5/10 = 50%
D. 0/10 = 0%
Answers
The estimated probability that Harriet will eat pizza for lunch every day next week is 5/10 = 50%
How to determine the probability?The simulation is represented as:
0 and 1 represents when pizza is not available2 to 9 represents when pizza is availableThe above means that the simulation that represents when she eats pizza for lunch must have all its digits to be from 2 to 9.
The results that represent eating pizza for lunch are:
73676 45467 95592 82739 38448
The count of the result is 5.
Hence, the probability is 5/10 = 50%

If the rate of inflation is 3.4% per year, the future price pt (in dollars) of a certain item can be modeled by the following exponential function, where t is the number of years from today.
pt = 2500(1.022t)
Find the current price of the item and the price 10 years from today.
Answers
Answer:
The answer is "3107.75".
Step-by-step explanation:
[tex]\text{Rate of inflation} = \frac{3.4 \%}{year}[/tex]
[tex]\to p(t)= 2500 (1.022)^t[/tex]
when t= 0
[tex]\to p(0) = 2500(1.022)^0[/tex]
[tex]= 2500 \times 1\\\\= \$ 2500[/tex]
When t=10
[tex]\to p(10)=2500(1.022)^{10}[/tex]
[tex]= 2500 \times 1.2431\\\\= 3107.75[/tex]

if tñ=2ñ+3, find S10
Answers
Answer:
[tex]S_{10}=280[/tex]
Step-by-step explanation:
Given that,
[tex]t_n=2n+3[/tex] ...(1)
We need to find the value of [tex]S_{10}[/tex].
Put n = 1 to find the first term.
[tex]t_1=2(1)+3=5[/tex]
Put n = 2 to find the second term.
[tex]t_2=2(2)+3=7[/tex]
Put n = 3 to find the third term.
[tex]t_3=2(3)+3=9[/tex]
Put n = 10 to find the tenth term.
[tex]t_{10}=2(10)+3=23[/tex]
It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :
[tex]S_=\dfrac{n}{2}(a+a_n)[/tex]
We have, n = 10, a = 5 and [tex]a_n=23[/tex]
So,
[tex]S=\dfrac{10}{2}(5+23)\\\\S_{10}=10\times 28\\\\=280[/tex]
So, the value of [tex]S_{10}[/tex] is equal to 280.
