Step-by-step explanation:
Please mark brainliest
Answer:
18π cm²
Step-by-step explanation:
The shaded region is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{80}{360}[/tex] ( r is the radius of the circle )
= π × 9² × [tex]\frac{2}{9}[/tex]
= 81π × [tex]\frac{2}{9}[/tex]
= 9π × 2
= 18π cm²

Answer:
p(8p + 7)
Step-by-step explanation:
Factorise is when you find the product of the question before taking away the brackets.
so, if you go p(8p + 7), you times p with everything inside the brackets giving you 8p^2 + 7
therefore, the answer is p(8p + 7)

how many solutions does the equation have y=1/2x-7 y=6x+2
Answer:
One solution, x=-18/11.
Step-by-step explanation:
y=1/2x-7
y=6x+2
---------------
1/2x-7=6x+2
1/2x-7-6x=2
1/2x-6x=2+7
1/2x-12/2x=9
-11/2x=9
x=9/(-11/2)
x=(9/1)(-2/11)
x=-18/11

solve this equation using synthetic division x³+2x²+4x+8=0
Answer:
Your answer is.......
x^3 + 2x^2 + 4x + 8=0 Note.. if x=-2 then whole equation is 0
So, (x+2) is one factor.
x^3 + 2x^2 + 4x + 8
=x^2(x+2)+4(x+2)
(x+2)(x^2+4)

Step-by-step explanation:
2 = 3x+14/4
2x4 = 4x4 4 cancels
8 = 3x+14
8-14 = 14-14 14 cancels
-6 = 3x
-6/3 = 3/3 3 cancels and you're left with x

Find the simple interest if the loan amount is $390 at a rate of 3% for 18 months.
Answer:
$17.55
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 390 × 0.03 × 1.5 = 17.55
I = $ 17.55
The simple interest accumulated
on a principal of $ 390.00
at a rate of 3% per year
for 1.5 years is $ 17.55.

f(x)=2x^2+9
Find f(-5)
Answer:
59
Step-by-step explanation:
Given
f(x) = 2x² + 9
f ( -5) = 2 * ( -5)² + 9
= 25 * 2 + 9
= 50 + 9
= 59
════════ ∘◦❁◦∘ ════════
Answer = 59════════════════════
Knownf(x) = 2x² + 9
════════════════════
Questionf(-5) = ?
════════════════════
Way to do#as you the x inside the (x) changed into (-5) it means that you need to change the x into -5.
f(-5) = 2(-5)² + 9
= 2 × 25 + 9
= 50 + 9 = 59
#So f(-5) = 59
