Answer:
Q = (9, 4 )
Step-by-step explanation:
Use the midpoint formula and equate to the coordinates of the midpoint.
M = ([tex]\frac{x_{1}+x_{2} }{2}[/tex] ) , ([tex]\frac{y_{1}+y_{2} }{2}[/tex] )
let the coordinates of Q = (x, y ) , R = (- 7, 0 ) , then
[tex]\frac{x-7}{2}[/tex] = 1 ( multiply both sides by 2 )
x - 7 = 2 ( add 7 to both sides )
x = 9
and
[tex]\frac{y+0}{2}[/tex] = 2 ( multiply both sides by 2 )
y = 4
Thus Q = (9, 4 )

Find the Average
100-90-80-89-75-0
Explain how u got ur answer
Someone help I will give brainlist for whoever explains it
Answer:
72.3
Step-by-step explanation:
So, to find the average you need to add all the numbers together and divide it by the amount of numbers there are, if that makes sense.
so in your question: 100 + 90 + 80 + 89 + 75 + 0= 434
and there are 6 numbers that you had to add together, so you divide 434 by 6, which is 72.3 so that's the answer! It's quite easy once you understand how to do it :)

Directions: Find the value of x.
Round angle measures to the nearest degree.
Given:
The figure of a right triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
In the given right triangle,
Hypotenuse = 15
Perpendicular = 12.5
Now,
[tex]\sin x^\circ=\dfrac{12.5}{15}[/tex]
[tex]\sin x^\circ=0.83333[/tex]
[tex]x^\circ=\sin^{-1}0.83333[/tex]
[tex]x^\circ =56.442345^\circ[/tex]
[tex]x\approx 56[/tex]
Therefore, the equation used to find x is [tex]\sin x^\circ=\dfrac{12.5}{15}[/tex] and the value of x is 56.

Answer:
64 square units
Step-by-step explanation:
if you spilt up the polygon you can find the area of the square and triangle making up the square.
length * width = Area; 6 * 8 = 48 sq units for the square part
1/2 * base * height = Area; 1/2 * 4 * 8 = 16 sq units for the triangle part
then add the two areas together for the area of the entire polygon:
48 + 16 = 64 sq units
What must be the sides of an equilateral triangle so that it's area should be equal to the area of an isosceles triangle with base 12m and equal sides 10m
Answer:
The sides of the equilateral triangle are 11.7 m.
Step-by-step explanation:
Let's find the area of the isosceles triangle:
[tex] A_{i} = \frac{bh}{2} [/tex]
Where:
b: is the base = 12 m
h: is the height
We can find the height by using Pitagoras:
[tex] x^{2} = \frac{b^{2}}{2} + h^{2} [/tex]
Where:
x is the hypotenuse = side of the triangle = 10 m
[tex] h = \sqrt{x^{2} - \frac{b^{2}}{2}} = \sqrt{(10)^{2} - 6^{2}} = 8 m [/tex]
Then, the area is:
[tex] A_{i} = \frac{12*8}{2} = 48 m^{2} [/tex]
Now, since the area of the isosceles triangle is equal to the area of the equilateral triangle:
[tex] A_{e} = A_{i} = 48 m^{2} [/tex]
[tex] A_{e} = \frac{bh}{2} [/tex]
The height of the equilateral triangle is given by:
[tex] b^{2} = \frac{b^{2}}{2} + h^{2} [/tex]
[tex] h = \sqrt{b^{2} - \frac{b^{2}}{2}} = \frac{b}{\sqrt{2}} [/tex]
Hence, the sides are:
[tex] A_{e} = \frac{1}{2}b\frac{b}{\sqrt{2}} = \frac{b^{2}}{2\sqrt{2}} [/tex]
[tex] b = \sqrt{A*2\sqrt{2}} = \sqrt{48*2\sqrt{2}} = 11.7 m [/tex]
Therefore, the sides of the equilateral triangle are 11.7 m.
I hope it helps you!
Answer:
The sides must be around 10.53 m
Step-by-step explanation:
You can calculate the area of isosceles dividing into 2 equal right triangles
Once you know that the area of the isosceles is 48 m²,solve for the side of the equilateral triangle
Formula for the Area: (A= area a = side)
A = (√3* a² ) / 4
48= (√3* a² ) / 4
Multiply both sides by 4
192 =√3* a²
Divide both sides by√3 ( √3 = 1.732050....)
110.851303 = a²
Square root on both sides
10 .5385...( 10.53 ) = a
9. The height of a ball thrown into the air is a quadratic function
of time. The ball is thrown from a height of 6 ft above the
ground. After 1 second, the ball reaches its maximum height of
22 ft above the ground. Write the equation of the function in
vertex form.
Answer:f(x)=-16(x-1)^2+22
Step-by-step explanation:
The equation for the trajectory of ball in the air is h(t) = -16t² + 32t + 6.
What is differentiation?The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) = lim h --> 0 (f(x + h) - f(x)) /(x + h - x).
It can also be said as the slope of the tangent for the function at a given point.
Given that,
The maximum height reached by the ball after 1 sec is 22 ft above ground.
And, the height at which it is thrown is 6 ft above the ground.
Which implies at 0 sec the height is 6 ft.
The quadratic function for the height can be written as,
h(t) = at² + bt + c
Substitute t = 0 to gat,
f(0) = a × 0² + b × 0 + c
=> c = 6
Now, for maximum height,
h'(t) = 0
=> 2at + b = 0
At maximum height t = 1
Then, the above expression becomes,
2a × 1 + b = 0
=> a = -b/2
Substitute t = 1 in h(t) = at² + bt + c to get,
22 = a + b + c
=> 22 = -b/2 + b + 6
=> b/2 = 16
=> b = 32
Then, a = -b/2
= -32/2
=-16
Thus substituting the corresponding values the equation can be written as h(t) = -16t² + 32t + 6.
Hence, the required equation for the path of the ball in the air is h(t) = -16t² + 32t + 6.

Write an explicit rule and recursive rule for a geometric sequence with a second term of 6 and a third term of 12.
explicit:
recursive:
Answer:
Explicit : [tex]a_n=3(2)^{n-1}[/tex]
Recursive: a₁ = 1
[tex]a_n=a_{n-1}(2)[/tex]
Step-by-step explanation:
We have to write the recursive formula for the geometric sequence with second term 2 and third term 12.
Geometric sequence will be in the form of,
a, ar, ar², ar³,...........
Here, r = common ratio
a = first term of the sequence
Here, ar = 6 ------(1)
And ar² = 12 ------(2)
By dividing equation (2) by (1),
[tex]\frac{ar^2}{ar}=\frac{12}{6}[/tex]
r = 2
From equation (1),
a(2) = 6
a = 3
Recursive formula of a geometric sequence is given by,
a₁ = a
[tex]a_n=a_{n-1}(r)[/tex]
Therefore, for the given sequence,
a₁ = 1
[tex]a_n=a_{n-1}(2)[/tex]
Similarly, explicit formula of the geometric sequence is given by,
[tex]a_n=a_1(r)^{n-1}[/tex]
[tex]a_n=3(2)^{n-1}[/tex]
A shoe store donated a percent of every sale to charity. a the total sales were $9,800 so the store donated $588. What percent of $9,800 was donated to charity?
Answer:
They donated 6%.
Step-by-step explanation:
The total sales were $9800.
The amount donated is $588.
We want to know what percent of 9800 is 588.
Let's make an equation.
what percent of 9800 is 588
x/100 • 9800 = 588
Divide by 9800.
x/100 = 0.06
Multiply by 100.
x = 6
They donated 6%.

Colin invests £1200 into his bank account. He
receives 3% per year compound interest. How
much will Colin have after 4 years?
Answer:
1,344
Step-by-step explanation: So first I multiplied 1,200 by .03 because in order to multiply by a percent you need to move it decimal back two times. After you multiply 1200 x .03 = 36. Next you would do 36 x 4 for the 4 years and it would = 144. Then you would add 144 to the original because it's interest and you would end up with Colin having 1,344.
A box contains 5 red, 4 white and 6 blue balls. If three balls are drawn at random without replacement, determine the probability that none of the balls selected is red.
Answer:
The probability that none of the balls selected is red ²⁴/₉₁
Step-by-step explanation:
Given;
number of red balls, R = 5
number of white balls, W = 4
number of blue balls, B = 6
Total number of balls, = 5 + 4 + 6 = 15
Probability of selecting 3 none red balls = P(WWW) or P(BBB) or P(WWB) or P(WBW) or P(BWW) or P(BBW) or P(BWB) or P(WBB)
[tex]P = (\frac{4}{15} \times \frac{3}{14} \times \frac{2}{13} ) + (\frac{6}{15} \times \frac{5}{14} \times \frac{4}{13} ) + (\frac{4}{15} \times \frac{3}{14} \times \frac{6}{13} ) + (\frac{4}{15} \times \frac{6}{14} \times \frac{3}{13} ) + \\\\(\frac{6}{15} \times \frac{4}{14} \times \frac{3}{13} ) + (\frac{6}{15} \times \frac{5}{14} \times \frac{4}{13} ) + (\frac{6}{15} \times \frac{4}{14} \times \frac{5}{13} ) + (\frac{4}{15} \times \frac{6}{14} \times \frac{5}{13} )[/tex]
[tex]P = \frac{24}{2730} + \frac{120}{2730} + \frac{72}{2730} +\frac{72}{2730} + \frac{72}{2730} + \frac{120}{2730} + \frac{120}{2730} + \frac{120}{2730} \\\\P = \frac{720}{2730} \\\\P = \frac{24}{91} \\\\[/tex]

There is a population of 17 bacteria in a colony. If the number of bacteria doubles every 229 hours, what will the population be 458 hours from now?
Answer:
68
Step-by-step explanation:
Step 1: Divide the asked hours by hours need to double
Step 2: Double the initial number of the population as per the result from step 1.
First divide 458 by 229, you will get 2
Now you double the initial population number twice
so 17 * 2 = 34 and again 34 * 2 = 68
