Answer:
113.1 cm²
Step-by-step explanation:
we are given the diameter of the circle (length is 12 cm), and the formula for the area of the circle, which is πr², where r is the radius
so first, we need to find the radius
the length of the radius is half the length of the diameter
so that means that r=d/2
r=d/2
r=12/2
r=6
therefore the length of the radius is 6
now square 6, which is the same as multiplying it by itself
6²=36
now, multiply the radius squared by π, which is often substituted for as 3.14 or 22/7
so if we were to do 22/7 for instance,
36*22/7≈113.14
round that to 113.1
there's your answer :)
Hope this helps!

What is the slope of the line that passes through the points (-5, -7)(−5,−7) and (4, -1) (4,−1)
Answers
Answer:
2/3
Step-by-step explanation:
REmember that the slope of a line is y/x. To find this, we must use the formula:
y2-y1/x2-x1=y/x
So this is -1 - -7/4- -5. The -1 -- 7 is actually -1+7. This is 6, meaning y equals 6.
The x is 4 - - 5 is actually 4+5. This is 9, meaning x is equal to 9.
We can now write this as y/x. This would be 6/9.
Once we simplfy this, we get 2/3.

2/3

Where does the graph of f(x) = (x + 9)(x - 4) cross the x-axis?
Answers
hi
f(x) = (x+9) (x-4)
if it's cross the x axis it's means f(x) = 0
(x+9) (x-4) = 0 means x+9 = 0 so x = -9 and x-4 = 0 so x = 4
answers f(x) = 0 for x = -9 and x = 4

In 1906, Colombia experienced an intense earthquake with a magnitude of 8.8 on the Richter scale. In 1995, Egypt experienced an earthquake that measured 7.3 on the Richter scale. Compare the intensities of the two earthquakes. Use a logarithmic model to solve. Round to the nearest whole number.
Answers
Answer:
The intensity of the 1906 earthquake was about 32 times the intensity of the 1995 earthquake.
Step-by-step explanation:
The earthquake with a magnitude of 8.8 is 178 times stronger than the earthquake that measured 7.3.
What is logarithm?A logarithm is the power to which a number must be raised in order to get some other number.
Given that, there are two earthquakes of magnitude 8.8 and 7.3
The energy released is given by:
[tex]log_{10} E = 4.4+1.5M[/tex]
For 8.8
E1 = 3.981071705534X10^17
For 7.3
E2 = 2.238721138568X10^15
E1/E2 = 3.981071705534X10^17/2.238721138568X10^15 ≈ 178
Hence, The earthquake with a magnitude of 8.8 is 178 times stronger than the earthquake that measured 7.3.

Answers
Answer:
x = 1/2 y = -1/3
Step-by-step explanation:
Split it into 2 equations:
10x-9y=8
and
21y+15x=0.5
10x - 9y = 8
Step 1: Divide both sides by 10:
x = (8+9y)/(10)
Substitute x = (8+9y)/(10) into 21y+15x=0.5 :
21y + (3(8+9))/(2) = 0.5
Solve for y
y= -1/3
Substitute y= -1/3 into x = (8+9y)/(10)
x = 1/2

Mid point = (–1 , –1)
Step-by-step explanation:
From the question given above, the following data were obtained:
(1, –6)
(–3, 4)
x₁ = 1
x₂ = –3
y₁ = –6
y₂ = 4
Mid point = (X, Y)
X = (x₁ + x₂)/2
X = (1 + –3)/2
X = (1 – 3)/2
X = –2/2
X = –1
Y = (y₁ + y₂)/2
Y = (–6 + 4)/2
Y = –2/2
Y = –1
Mid point = (X, Y)
Mid point = (–1 , –1)

How do you know if a number is rational irrational or not real number
Answers
Answer:
A rational number can expressed as a whole number, integer, square root, fraction, and more as long as it's not imaginary. However, the number has to be clean like 1/2=0.5, 1/3=0.333, -1, 200. If it is a number that goes on forever and is not repeated like 1.22222, then it's an irrational number like pie-3.14159..., 5/0, 2.201845. If you have an imaginary number- 6i, then this would be considered as non real numbers like x+2, red, wind, and y/7.

Answers
Answer:
m = 15
Step-by-step explanation:
Since ∆ABC ~ ∆QRS, this implies that the ratio of their corresponding side lengths are equal. Thus:
QR/AB = QS/AC
QR = m
AB = 10
QS = 9
AC = 6
Plug in the values
m/10 = 9/6
m/10 = 3/2
Cross multiply
2*m = 3*10
2m = 30
m = 30/2
m = 15
