Answer:
0.75.
Step-by-step explanation:
1) the required vertical distance is the distance between two vertexes.
2) according to the item 1, the coordinates of the vertexes are:
(y=x²+1): x₀=0; y₀=1;
(y=x-x²): x₀=0.5; y₀=0.25;
3) according to the item 2, the distance between 1 and 0.25 is 0.75.
If you randomly select a letter from the phrase "Brandon loves to eat at Red Robin," what is the probability that you select a consonant? (Your answer must be in the form of a reduced fraction.)
Answer:
16/27
Step-by-step explanation:
Formula for probability:
favourable outcomes/possible outcomes
using this we can find the answer.
let's first count all the consonants. there are 16 consonants and 27 total letters. that means that your answer would be 16/27.

A boat travels 1/5 of a mile on 7/9 gallon of gas. How many miles can the boat travel on 1 gallon of gas
Answer:Since we know the boat uses 25 gallons of gas per 64 miles, we can divide 64 miles by 25 gallons to get the rate of gallons per hour.
64 ÷ 25 = 2.56 gallons of gas every hour.
Using this information, we can multiply the amount of gas used for one hour, 2.56 gallons, by the 125 gallons of gas that the problem suggests, 125, to find the number of miles the boat can travel on the amount of gas.
2.56 x 125 = 320 miles
Answer: The boat can travel 320 miles on 125 gallons of gas.

Find the area and circumference of each shaded sector. Use 3.14 for . Round to the
nearest tenth.
Answer:
Area = 226.1 ft^2
and circumference = 61.7 ft.
Both to the nearest tenth.
Step-by-step explanation:
The area of shaded part
= 1/2 *3.14 r^2
= 1/2 * 3.14 * 12^2 = 226.1 ft^2.
Circumferences of the shaded part = diameter + length of the semicircle
= 2 *r + 3.14 * r
= 2*12 + 3.14 * 12
= 61.68 ft.

Which table shows a data o for an antenna that revolves at exactly twice the rate of the antenna described in the graph?
The table shows a data for an antenna that revolves at exactly twice the rate of the antenna described in the graph is Table D.
How to illustrate the rate?The formula to calculate the rate will be:
= Change in revolution/Change in time
The rate of the given antenna will be:
= (60 - 30)/(4 - 2)
= 30/2
= 15
Also, the rate of antenna 1 is 23, antenna 2 is 25, antenna 3 is 2. The rate for antenna 4 will be:
= (720 - 660)/(24 - 22)
= 60/2
= 30
It can be seen that 30 is double of 15.
Therefore, table D revolves at exactly twice the rate of the antenna.

Write the algebraic expression that matches each graph.
Answer:
f(x) = |x - 2| - 2
Step-by-step explanation:
Based on the shape of the graph, it's an absolute value function.
so the template for it is f(x) = |x|
From there, you can make some additions to show how much the graph has shifted from the template equation
since the graph went over to the left by 2 units and down by 2 units, this is added into the equation as follows:
f(x) = |x - 2| - 2

Answer:
-0.182
Step-by-step explanation:
Given expression:
0.46 + (-0.642)It should be noted that;
1. Positive integer + (Negative integer) = Positive integer - Positive integer
a + (-b) = a - b2. Positive integer - (Negative integer) = Positive integer + Positive integer
a - (-b) = a + bOur case is point 1. Therefore,

g ( t ) = | t | - 3 ; find g ( 3 ) , g ( -5 ) , and g ( 0 )
Answer:
g(3) = 0. g(-5) = 2. g(0) = -3
Step-by-step explanation:
simply put whatever is inside the brackets, into where t is in the equation
e.g:
|t| - 3 for g(3) is: |3| - 3 = 0
the two lines around t just mean that whatever is inside you should always turn positive. so |-1| = 1 and |-3 + 1| = 2

Answer:
Axis of symmetry: x = 5
Vertex form: y = -4(x - 5)² + 3
Step-by-step explanation:
Given ordered pairs: (2, -33) (3, -13) (4, -1) (5, 3) (6, -1)
Axis of Symmetry
As this is a parabola, it will be symmetrical.
To determine the axis of symmetry, identify two ordered pairs that have the same y-values and find their midpoint.
Two ordered pairs with the same y-value: (-4, 1) and (6, -1)
Midpoint of x = 4 and x = 6 is: x = 5
Therefore, the axis of symmetry is x = 5
Vertex form
Vertex form of a quadratic equation: y = a(x - h)² + k
(where (h, k) is the vertex)
The axis of symmetry is the x-value of the vertex of the parabola.
As we have been given the point when x = 5, the vertex is: (5, 3)
Substituting this into the formula:
⇒ y = a(x - 5)² + 3
To find the value of a, substitute any of the other points into the formula and solve for a.
Using (4, -1)
⇒ a(4 - 5)² + 3 = -1
⇒ a(-1)² = -4
⇒ a = -4
Therefore, the vertex form of the parabola is:
y = -4(x - 5)² + 3

What is the area of a square?A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.
A square is a 4 sided polygon where all the sides are of equal length.
The area of the square is the square of any one of its side
Let a be the side of the square
Area of the square = a²
Given data ,
Let the area of the square be represented as A
Now , the value of A is
Let the area of the semicircle be S
Let the total area of the figure be T = S + A
where A = ( 4 )² = 16 cm²
And , S = ( πr² ) / 2
S = 3.14 x ( 2 )² / 2
S = 6.28 cm²

In this case, we have the number 10,000 with 4 zero's and we're going to add that to the back of 14 which gives us the answer 140,000 And they both have 4 zero's. :)

A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape. (a) What is the probability that both grapes are green? (b) What is the probability that Henry eats a red grape then a green grape?
Answer:
A. 28/253
B. 60/253
Step-by-step explanation
A. first step is to add all the grapes up which = 23
then you would put the
green grapes/ the total which would be 8/23
since henry ate one grape you would subtract 8-1 and then 23-1 and you would get 7 and 22
then you would put 7/22 and multiply 8/23 which gets you 28/253
B. first you put red grapes over total grapes which are 15/23
then,
you would do the green grapes which are 8/22
you would multiply 15/23 and 8/22 which = 60/253
