What is the distance between points A and B shown in the graph below
Answer:
[tex]D = 7\sqrt 2[/tex]
Step-by-step explanation:
Given
[tex]A = (-3,-4)[/tex]
[tex]B = (4,3)[/tex]
Required
The distance between them
This is calculated as:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
So, we have:
[tex]D = \sqrt{(3-(-4))^2+(4-(-3))^2}[/tex]
[tex]D = \sqrt{7^2+7^2}[/tex]
[tex]D = \sqrt{2(7^2)}[/tex]
[tex]D = 7\sqrt 2[/tex]
Find the area of the sector and explain please
Answer:
78.5398
Step-by-step explanation:
Area of a circle:
a=[tex]\pi[/tex]r²
Radius is 10.
a=[tex]\pi[/tex]10²
a=[tex]\pi[/tex]100
a=314.15926
90° is one quarter of the circle, so multiply it by 0.25.
314.15926x0.25=78.5398
I don't know how many places the directions want it rounded to. If it said to use 3.14 for pi, the answer would just be 78.5.

Find the area of the following
triangle:
4.2 cm
3 cm
10 cm
A= [?] cm
Answer:
15 cm
Step-by-step explanation:
Base x height / 2 = Area(of a triangle) =
3 x 10 / 2 =
15 cm
The solution is : the area of the following triangle is, 15 cm².
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
Here, we have,
given that,
4.2 cm
3 cm
10 cm
We know that,
area = bh/2
i.e. we get,
Base x height / 2
= Area(of a triangle)
substituting the values, we get,
= 3 x 10 / 2
= 15 cm²
Hence, The solution is : the area of the following triangle is, 15 cm².

Here is a grid of squares.
Write down the ratio of the number of unshaded squares to the number of
shaded squares.
Answer:
3/10
Step-by-step explanation:
............iam not sure
The required ratio of the unshaded square to the shaded square is 7 : 3.
Given that,
To determine the ratio of the number of unshaded squares to the number of shaded squares.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Number of shaded squares = 3
number of unshaded squares = 7
Required ratio = 7 / 3 = 7 : 3
Thus, the required ratio of the unshaded square to the shaded square is 7 : 3.

What is the area of the polygon shown below?
Answer:
66
Step-by-step explanation:
first you find the area of the rectangle
5*12=60
then you find the area of the triangle
to find the length of the dotted line you need to subtract 9 from 12 which is 3
to find the length of the line adjacent to the dotted line you need to subtract 5 from 9 which is 4
use the triangle area formula 3*4*1/2=6
add the areas of the triangle and the rectangle 60+6=66

Item 15
A crowd-funding project has received $16,770, which is $1230 less than 90% of the goal amount. What is the goal amount?
Answer:
The goal is $19,800.
Step-by-step explanation:
$16,770 is $1,230 less than %90 of the goal. If you add 16,770 and 1,230, you get 18,000. Then you have to multiply that by 1.10 to get it to the goal. That is how you get $19,800, which is the answer.

Four equivalent forms of a quadratic function are given. Which form displays the zeros of function h?
OA. f(x) = -4(x2 - 4)
OB. h() = -4(x - 2)(x + 2)
Och(x) = -47 +16
OD. H(x) = -2(2x - 3)
Answer:
Step-by-step explanation:
h(x) = -4(x-2)(x+2)
The zeros are 2 and -2.
Answer:
90
Step-by-step explanation:
OA. f(x) = -4(x2 - 4)
OB. h() = -4(x - 2)(x + 2)
Och(x) = -47 +16
OD. H(x) = -2(2x - 3)

Step-by-step explanation:
The following data were given in a study of a group of 1000 subscribers to a certain magazine. In reference to job, marital status, and education, there were
312 professionals,
470 married persons,
525 college graduates,
42 professional college graduates,
147 married college graduates,
86 married professionals,
25 married professional college graduates.
(i) Let a person be picked at random. Determine the probability that the person is married or professional or college graduate.
(ii) Explain why the numbers reported in the study must be incorrect.
Answer:
[tex](a)[/tex] [tex]P(M\ or\ P\ or\ C) = 1.307[/tex]
(b) See Explanation
Step-by-step explanation:
Given
[tex]P = 312[/tex] ---- Professionals,
[tex]M = 470[/tex] ----- Married persons,
[tex]C = 525[/tex] ---- College graduates,
[tex]PCG = 42[/tex] ----- Professional college graduates,
[tex]MCG = 147[/tex] ----- Married college graduates,
[tex]MP = 86[/tex] ---- Married professionals,
[tex]MPCG = 25[/tex] ---- Married professional college graduates
[tex]Total =1000[/tex]
Solving (a): P(M or P or C)
This is calculated as:
[tex]P(M\ or\ P\ or\ C) = P(M) + P(P) + P(C)[/tex]
[tex]P(M\ or\ P\ or\ C) = \frac{n(M) + n(P) + n(C)}{Total}[/tex]
[tex]P(M\ or\ P\ or\ C) = \frac{470 + 525 + 312}{1000}[/tex]
[tex]P(M\ or\ P\ or\ C) = \frac{1307}{1000}[/tex]
[tex]P(M\ or\ P\ or\ C) = 1.307[/tex]
(b) In probabilities, the probability of an event or collection of events must not exceed 1 and must not go below 0.
In (a) above, the calculated probability exceeds 1.
Because of this single reason, the collected data is incorrect
