Step-by-step explanation:
we know ,
area of circle =πr^2
hence we get from the figure that the diameter of circle is 19 cm and we can find radius
r=d/2
r=18/2=9cm
area of semicircle =πr^2/2
area of Semi circle equals to =22*(9)^2/7/2
=127.2857143
Answer:
Today: Sunday, 11 October 2020
Hour: 23.05 WIB (Indonesian)
_________________________
D = 18
r = 18 ÷ 2 = 9
area of semicircle = πr²/2
area of semicircle = 3.142 . 9²/2
area of semicircle = 3.142 . 81/2
area of semicircle = 254.502/2
area of semicircle = 127.251 cm²
Given f(x) = 2x2 -x + 3, find f(-2).
Answer:
is 2x2 multiplying them or is x the letter ?

Answer:
1. b⁵
2. +16m⁹
Step-by-step explanation:
1. Add exponents: b³⁺² = b⁵
2. Negative and Negative = positive
2*8 = 16
m⁴⁺⁵ = m⁹
Hence: + 16m⁹
Answer:
[tex]1) \: {b}^{5} [/tex]
[tex]2) \: \: + 16 {m}^{9} [/tex]
Step-by-step explanation:
[tex] {b}^{3} \times {b}^{2} = {b}^{3 + 2} = {b}^{5} [/tex]
we know that
[tex]( - ) \times( - ) = ( + )[/tex]
So
[tex] - 2 {m}^{4} \times - 8 {m}^{5} \\ = + 16 {m}^{9} [/tex]
Can someone help me
[tex]f(x) = {2}^{x} [/tex]
You can answer them yourself but I like to help you to do it buddy.
Let's go....
[tex]f(1) = {2}^{1} = 2 [/tex]
[tex]f(2) = {2}^{2} = 4 [/tex]
[tex]f(3) = {2}^{3} = 8 [/tex]
[tex]f(4) = {2}^{4} = 16 [/tex]
[tex]f(5) = {2}^{5 } = 32 [/tex]
[tex]f(6) = {2}^{6} = 64 [/tex]

And we're done.
Thanks for watching buddy good luck.

length of the shorter piece.
Answer:
the shorter piece is 30 inches.
Step-by-step explanation:
3x + x = 120
4x =120
x =30
Anybody know this answer?
Answer:
x = 29
Step-by-step explanation:
The sum of the 3 angles is 180 degrees since it is a straight line
x-1 + 3x+2 + 2x+5 = 180
Combine like terms
6x +6 = 180
Subtract 6 from each side
6x+6-6= 180-6
6x =174
Divide y 6
6x/6 =174/6
x = 29
Answer:
it's 29
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.

18) Write an Equation Given the Slope and y-Intercept
The equation for a line has a slope of 1/3 and y-intercept of - 6.
A) y = 1/3x + 6
B) y = 3x - 6
C) y = 1/3x - 6
Answer:
C) y = 1/3x - 6
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
1/3=m
-6=b
then plug in the numbers to get: y=1/3x - 6

x - y = 1 in slope intercept form
Answer:
y = x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
x - y = 1 ( add y to both sides )
x = y + 1 ( subtract 1 from both sides )
x - 1 = y , that is
y = x - 1 ← in slope- intercept form

Milene é doceira e a seguir está uma representação dos bombons que ela fez no dia. Do total dos bombons que fez 2/3 são de coco. Escreva a quantidade que representa os bombons de coco. *finja que aqui tem 24 bombons*
Answer:
16 bombons de coco
Step-by-step explanation:
A partir da pergunta, somos instruídos a fingir que o número total de bombons (chocolate) que ela fez = 24 bombons
Do total de chocolates que ele fez, 2/3 são de coco.
Portanto, a quantidade que representa os doces de coco é representada como:
2/3 × 24
= 16
Portanto, a quantidade de bombons de coco = 16
(3x^2 - 2x + 1) + (1x^2) =
Answer:
4x^2 - 2x + 1
Step-by-step explanation:
Since you are adding, you can drop the parentheses because they are unnecessary. Combine like terms.
(3x^2 - 2x + 1) + (1x^2) =
= 3x^2 - 2x + 1 + 1x^2
= 4x^2 - 2x + 1
