Answer:
22.21
Step-by-step explanation:
The slope of a linear function is calculated by rearranging the equation to its general form, f(x) = mx + c; where m is the slope. The vertex of a quadratic function is calculated by rearranging the equation to its general form, f(x) = a(x – h)2 + k; where (h, k) is the vertex.

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS PLEASE AND EXPLAIN WHY THAT IS THE ANSWER. Find the value of X. Then signed the measure of each labeled angle.
X=_____
The two angles sum to equal 180 degrees.
4x + 8x = 180
12x = 180
X = 180/12
X = 15
Answer:
Soln:4x°+8x°=180°
12x°=180°
or,x°=180°/12
or,x°=15
4x°=4×15°=60°
8x°=8×15°=120
Henry opened his account with a starting amount of $920, and he is going to take out $60 per month. Write an expression for the amount of money in Henry’s account after x months.
$920 - $60x
Step-by-step explanation:
after one month, he try would have taken out 60 x 1 dollars, after two months, 60 x 2, 3 months, 60 x 3, etc. so after x months he would have taken out 60x (60 times x) dollars. if he starts with 920 dollars, he would be left with $920 - $60x.

Drag each tile to the correct box. Johnny has a bag full of letter tiles. He picks one tile and then replaces it. He’s checking to see how many times he picks the letter A. Arrange the following situations, starting with the situation that gives the largest difference between relative frequency and actual probability and ending with the situation that gives the smallest difference. Johnny performs the experiment 75 times. Johnny performs the experiment 50 times. Johnny performs the experiment 20 times. Johnny performs the experiment 32 times. , , ,
Based on the number of times Johnny performs the experiment, the order from the largest difference in relative frequency and actual prob. to the smallest is:
The difference between absolute probability and relative frequency will be larger if the number of experiments performed is smaller.
This is why the largest difference was seen when Johnny performed the experiment 20 times and the smallest difference was seen when the experiment was done 75 times.

a shipping box is built out
of cardboard. It is 13 m
long, 7 m wide and 3 m high. How much cardboard
le needed to build the box?
Step-by-step explanation:
Length of a shipping box (L) = 13m
breadth of a shipping box (b) = 7m
height of a shipping box (h) = 3m
Now,
Volume of a shipping box (v) = L*b*h
= 13*7*3

Answer:
(a) 5 units up
(b) 3 units right
(c) 7 units left
Step-by-step explanation:
Parent equation: [tex]y=x^2[/tex]
Transformed equation: [tex]y = (x - h)^2+ k[/tex]
h translates the parabola horizontally
If h > 0 then the translation is h units to the right.
If h < 0 then the translation is h units to the left.
If h = 0 then there is no horizontal translation.
k translates the parabola vertically
If k > 0 then the translation is k units up.
If k < 0 then the translation is k units down.
If k = 0 then there is no vertical translation.
Part (a)
Given equation: [tex]y=x^2+5[/tex]
Rewriting in transformed equation form: [tex]y=(x-0)^2+5[/tex]
Therefore, the parabola is translated 5 units up.
Part (b)
Given equation: [tex]y=(x-3)^2[/tex]
Rewriting in transformed equation form: [tex]y=(x-3)^2+0[/tex]
Therefore, the parabola is translated 3 units right.
Part (c)
Given equation: [tex]y=(x+7)^2[/tex]
Rewriting in transformed equation form: [tex]y=(x+7)^2+0[/tex]
Therefore, the parabola is translated 7 units left.
Part (d)
Given equation: unreadable
It is possible that a distribution of data may not actually contain one of the measures of central tendency. Which one might that be?
Question 3 options:
Range
Mode
Mean
Median
The measure of central tendency of a distribution of data that can take multiple value is the mode
How to determine the measure of central tendency?In a given dataset;
The range is the difference between the least and the highest data elementThe mean is the average valueThe median is the middle valueAll the above measures can take only one value in a dataset
However, the mode can take multiple values, because it represents the data element with the highest frequency (and multiple data elements can have the same frequency)

A flour moth trap has the shape of a triangular prism that is open on both ends. An environmentally safe chemical draws the moth inside the prism, which is lined with an adhesive. What is the surface area of the prism-shaped trap?
Answer:
72 in²
Step-by-step explanation:
since the trap is open left and right, we don't include these side areas.
so, all we have for the surface area are
the top rectangle (2.5 in × 12 in),
the bottom rectangle (2 in × 12 in)
the back rectangle (1.5 in × 12 in)
for the total surface area we need to to add all 3 areas up.
in our case we get
2.5 × 12 = 30 in²
2 × 12 = 24 in²
1.5 × 12 = 18 in²
total is then
30 + 24 + 18 = 72 in²

(2 – 3i) and (4 + 3i)
The product of the two complex numbers above is a - 6i, where a is a constant. What is the value of a ?
(Note: i = -1)
Expanding the product gives
(2 - 3i) (4 + 3i) = 8 - 12i + 6i - 9i² = (8 + 9) + (6 - 12) i = 17 - 6i
so a = 17.

At a farm the ratio of cows to horses was 7 : 2 if there were 21 cows at the farm, how many horses were there?
Select two ratios that have the same unit rate as 2:4
A. 1:3
B. 1:2
C. 3:5
D. 5:10
E.4:6
F. 6: 10
Answer:
B and D
Step-by-step explanation:
2:4 when divided by 2 gets you 1:2
and 2:4 multiplied by 2.5 gets you 5:10
Answer:
B and D
Step-by-step explanation:
So basically we have to find the unit rate of 2:4.
(remember to find the unit rate we have to simplfy the ratio until one of the quantities is 1)
2:4 (divide by 2 on each side)
1:2 (B)
now we can use this unit rate of 1:2 to find out other equal ratios
1:2 (multiply 5 on both sides)
5:10 (D)
1. Jeremy rode his bike 9 miles in 3
hours. At this same rate, what is the
total number of miles Jeremy could
ride in 4 hours?
Answer:
12
Step-by-step explanation:
first, find the unit rate. to get the unit rate, we would figure out how many miles he can ride in 1 hour. to get this, divide by 3, to get hours to 1 instead. now divide miles by 3 to get 3 mph. multiply by 4, and you have your answer.
