Answers
Answer:
12 in
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the missing side , then
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12

3. A cosmetic retailer surveyed 200 customers on which of their top two lipstick shades the
customers preferred. The results are shown in the table. Find the probability of randomly
selecting a customer who prefers the Pretty Pink shade, given they are among the group of 30-
year-olds?
Answers
Answer:
.440
Step-by-step explanation:
Based on the number of people in the 30 - 39 age group, the probability of picking one who prefers Pretty Pink is 0.440.
What is the probability of a Pretty Pink preference in 30 - 39?This can be found as:
= Number of 30 - 39 year olds who preferred Pretty Pink / Total number of 30 - 39 year olds surveyed
Solving gives:
= 22 / (28 + 22)
= 22 / 50
= 0.440

Please please help me with this question please now and show your steps
Answers
a) y-intercept
The y-intercept is the point where it crosses the y axis so x would 0.
So putting in 0 for x:
y = x^2 - 8x + 7
y = 0^2 - 8(0) + 7
y = 0 - 0 + 7
y = 7
The y intercept is at the point (0,7).
b)
The zeroes are the points where it crosses the x axis so it’s when the y is set to 0.
0 = x^2 - 8x + 7
Since it’s a quadratic equation we have to factor it. We fill in 2 numbers that add to -8 and multiplied to equal 7.
(x +____)(x+ ____)
The 2 numbers are 7 and -1 because -1*-7=7 and -7+(-1)=-8. So:
0 = (x-7)(x-1)
So now we have x-7 and x-1 equaling some quantity. If either of those happens to equal zero, it makes the whole equation 0, because (x-7)0=0 and 0(x-1)=0
So we can set each of it separately to 0 to solve for x.
x-7=0
x= 7
x-1=0
x= 1
The zeroes are at the points (1, 0) and (7, 0)
C.
The Vertex Form of a Quadratic is:
y = a(x-h)^2 + k. And the vertex is (h, k)
y = x^2 - 8x + 7
y - 7 = x^2 - 8x
We want to complete the square by adding some number to both sides of the equation so that when we factor it we are going to get (x-a)(x-a).
So take half of 8 to get two equal numbers that would be our “a”. 8/2=4 so we want (x - 4)(x- 4).
(x-4)(x-4) multiplies out to x^2 - 8 + 16.
continuing,
y - 7 = x^2 - 8x
Add 16 to both sides.
y - 7 + 16 = x^2 - 8x + 16
y + 9 = (x-4)(x-4)
y + 9 = (x-4)^2
y = (x-4)^2 - 9 is the vertex form.
The vertex is at the point (4, -9). So the axis of symmetry is at the line x = 4.
D. The vertex is solved in C as the point (-4, -9).
can anyone explain to me how to do this question ? ty !!
Answers
Step-by-step explanation:
use a little imagination.
the whole thing is a combination of churches and half- circles.
and you know the formula for the area of a circle ?
A = pi×r²
so, the only difficulty is to find the circles and then the radius of each involved circle.
when you look at the picture, the shaded area is almost identical to the lower half of the main circle.
2 bumps "look" over into the other side, but one equally sized bump is removed from this lower half.
so, as a first step we will calculate the area of the lower half of the main circle.
the diameter is 24 m, so the radius is half of that : 12m
the area of the large circle is therefore
pi×12² = 144×pi m²
since we only need the (lower) half, we divide this by 2 :
144×pi / 2 = 72×pi m²
the bumps up and down are actually half-circles too. just of smaller circles.
since AB = BC = CD, we know each of these lines are 1/3 of the main diameter AD.
so, the diameter of the smaller circles is 24/3 = 8 m
and their radius is half of that = 8/2 = 4m
the area of such a small circle is therefore
As = pi×4² = 16×pi m²
and a small half-circle area is then
16×pi / 2 = 8×pi m²
so, for the full shaded area I need to take the large half-circle and add 2 small half-circles, and then subtract 1 small half-circle.
so, in total I only need to add 1 small half-circle.
Ashaded = 72×pi + 8×pi = 80×pi m²
i need an explanation what....wajfasjf

In the coordinate plane, point A(-1,-1) is translated to point A' (-3.-3). Under the same translation, the points B(-4,-4) and C(5.-5) are translated to B' and C' respectively. What are the coordinates of B' and C'?

Consider the coordinates of A and A'
A (- 1, - 1 ) , A' (- 3, - 3 )
- 1 to - 3 in both the x and y direction means subtracting 2 units , then
translation rule is
(x, y ) → (x - 2, y - 2 ) , then
B (- 4, - 4 ) → B' (- 4 - 2, - 4 - 2 ) → B' (- 6, - 6 )

Answer:
1 1/6
Step-by-step explanation:
Find the common denominator for 6, 3, 2
6 is divisible evenly by all three of those numbers so 6 is the lowest common denominator.
Convert all the fractions into sixths.
The first fraction is already done.
1/3..... the denominator needs to be multiplied by 2 so you have to multiply the numerator by the same amount.
1/3 x 2/2 = 2/6
1/2.... the denominator needs to be multiplied by 3 so you do the same thing to the numerator.
1/2 x 3/3 = 3/6
Now you have
2/6 + 2/6 + 3/6 = 7/6
Simplify the answer
6/6 = 1 so remove 6/6 from 7/6 and you are left with just 1/6
So your answer will be 1 and 1/6 or 1 1/6
