Find the area of this semi-circle with diameter, d = 58cm.
Give your answer rounded to 2 DP.
Answer:
The area of the semi-circle
A = 1320.37 cm²
Step-by-step explanation:
Explanation:-
Given the diameter of the circle 'd' = 58cm
The radius of the circle 'd' = 2r
[tex]r = \frac{d}{2} = \frac{58}{2} = 29[/tex]
The area of the semi-circle
[tex]A = \frac{1}{2} \pi r^{2}[/tex]
[tex]A = \frac{1}{2} (3.14) ((29))^{2}[/tex]
A = 1320.37 cm²
Factor : 21y^2 + 105y
Answer:
The answer is 21y(y + 5). hope this helps

Aubrey invested $7,100 in an account paying an interest rate of 5.6% compounded quarterly. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 19 years?
The amount of money in Aubrey's account after 19 years will be $20,424.
What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Aubrey invested $7,100 in an account paying an interest rate of 5.6% compounded quarterly.
Assuming no deposits or withdrawals are made.
Then the amount of money in Aubrey's account after 19 years will be
P = $ 7100
r = 0.056/4 = 0.014
n = 4 x 19 = 76
Then we have
A = 7100 (1.014)⁷⁶
A = $ 20,424

The measure of the side BC of the triangle is BC = 28
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as A B C
Let the second triangle be represented as D E F
Now , the measure of side A D = measure of side D B
And , the measure of side A F = measure of side F C
The measure of side D F = 14
The measure of side D E = 10
The triangles ABC and DEF are similar triangles
From the Triangle segment theorem ,
D F = B C / 2
Substituting the values in the equation , we get
14 = B C / 2
Multiply by 2 on both sides of the equation , we get
The measure of side BC of triangle = 28
Hence , the measure of side B C is 28

There are 31 fish in a tank. The fish are either orange or red. There are 7 more orange fish than the number of red fish. How many fish are orange? How many fish are red?
Answer:
There are 12 red fish, 19 orange fish
Step-by-step explanation:
Let y rep amount of red fish
y + 7 = Amount of orange fish
y + y + 7 = 31
2y = 31 - 7
2y = 24
y = 12
Then
y + 7
12 + 7 = 19

which of these graphs represent a function
Given the figure below, calculate its perimeter.
Answer:
24.58
Step-by-step explanation:
In the big triangle, you see two little triangle
one of the little triangle is a 45-45-90 triangle (the number represent the angle measures of the triangle)
this means that the legs are the triangle can be considered one, and the hypotenuse can be considered [tex]\sqrt{2}[/tex]
so in any 45-45-90 triangle, if you have a leg that is 4, then you know the other leg is also 4, and the hypotenuse would be 4 times [tex]\sqrt{2}[/tex] (aka 5.65)
the other triangle is a 30-60-90 triangle (the number represent the angle measures of the triangle)
this means that the smallest leg of the triangle can be considered one, and the other leg (the bigger one) can be considered 2, and the hypotenuse can be considered [tex]\sqrt{3}[/tex]
so the smallest leg here is 4, this means that the other leg would be 2 times 4 (aka 8)
and the hypotenuse would be 4 times [tex]\sqrt{3}[/tex] (aka 6.93)
so the sides that count to the perimeter of the given triangle would be 4, 5.65, 8, and 6.93
add those up and you get: 24.58

Answer:
1. 4y = 3x - 8
2.y-7 = -2(x + 4)
Step-by-step explanation:
1. The general equation form is;
y = mx + b
m is slope b is y-intercept
so we have;
y= 3/4x - 2
Multiply through by 4
4y = 3x -8
2. The point-slope form is;
y-y1 = m(x-x1)
y-7 = -2(x + 4)
