Draw a 45o angle

Bisecting means dividing the angle into 2 halves, which is 22.5o each

Answer:

(a) --> f(x) = -(x - 4)²

(b) --> f(x) = x² + 3

(c) --> f(x) = (x - 2)²

(d) --> 6. f(x) = 3 - x²

Parent function of all the graphs is y = x²

(a)

The graph makes a sad face meaning the coefficient will be negative.

Comparing to the parent function y = x², the graph has been translated 4 units to the right.

Equation: f(x) = -(x - 4)²

(b)

The graph makes a happy face meaning the coefficient will be positive.

Comparing to the parent function y = x², the graph has been translated 3 units up.

Equation: f(x) = x² + 3

(c)

The graph makes a happy face with translation 2 units to the right.

Equation: f(x) = (x - 2)²

(d)

The graph makes a sad face with translation 3 units up across y axis.

Equation: f(x) = -x² + 3

f(x + a)  :  translation a units left in the x axis.

f(x - a) : translation a units right in the x axis.

f(x) + b :  translation b units up in the y axis.

f(x) - b : translation b units down in the y axis.

Answer:

angle A=125 angle B= 114 angle C= 121

Step-by-step explanation:

first you have to find x so that you can find each angle

the interior angles of a triangle is equal to 360

add the angles together x+x+7+x+11=360

combine like terms 3x+18=360

subtract 18 on both sides 3x=342

divide by 3 on both sides x=114

to find angles:

plug in X to each side

(114)+7 = angle C

(114)+11= angle A

114= angle B

The true statement about the given diagram is: A. segment XZ is perpendicular to segment WY.

Perpendicular segments are line segments that intersect at a point to form right angles which is equal to 90 degrees. The point where perpendicular segments meet have an angle measure of 90 degrees.

In the given diagram, we are told that angle YXZ is equal to  90 degrees. This means that at the point where segment XZ and segment WY meet have an angle measure of 90 degrees.

This means they are perpendicular segments.

Therefore, the true statement about the given diagram is: A. segment XZ is perpendicular to segment WY.

The figure will be a sphere with center T and radius 8 1/2 inches, that is, option D.

A circle is a closed curve constituting of the set of all points in a plane that are equidistant from a given point. This point is the center of the circle and the distance is the radius of the circle.

A circle is a 2-dimensional figure, and the two dimensional does not contain the set of all points in the 3-dimensional plane.

A sphere is a round geometrical object and is the set of all points that are equidistant from a given point, in the three-dimensional space.

Here, we are given that there is a point T and we need to describe the collection of all points in the same plane that are 8.5 inches from point T.

Going by the definitions given above, we can infer that it is a sphere with center T and radius 8.5 inches. If we take it to be a circle then it will not include the points in the 3D plane, hence, sphere.

The value of the z-score is calculated as 0.259.

The standard normal distribution is the variable of a normal distribution to mean 0 and variance 1. The normal distribution follows a bell curve. The z-table aids in determining the area beneath the curve.

Now, as per the given question;

The formula for the z-score is;

z = (x - μ)/σ

x = sample size

σ = standard deviation

μ =  mean of the sample

For the given values in the question;

x = 31.1

σ = 7.7

μ = 30.9

Substitute the given values in the formula to fine z-score;

z-score = (31.1 - 30.9)/7.7

z-score = 0.259

Therefore, the value of the z-score is computed as 0.259.

What are simultaneous equations?

Simultaneous equations are two or more equations that must be solved concurrently in order to derive the values of the unknown, the total sales, as well as the total number of tickets sold, can be modeled into equations as below:

let x be the number of adult tickets

let y be the number of children's tickets

9x+5.90y=1000.60....... equation 1

x+y=137.................. equation 2

solve for y in equation 2

y=137-x

substitute for y in equation 1

Answer:

3311

Step-by-step explanation:

The steps are as follows

1. Divide 456 by 5. This gives a quotient of 91 with a remainder of 1. This remainder becomes the least significant digit of the new base number. This would be the right most digit. So the number is _ _ _ 1

2. Take the quotient, 91, divide by 5 again. This gives a quotient of 18 with a remainder of 1. Put this remainder to the immediate left of the previous value. So we have the number as _ _ 1 1

3. Take the previous quotient, 18, divide by 5 again. 18/5 gives quotient of 3 with a remainder of 3. Put this to the immediate left of the previous number giving the number as _ 3 1 1

4. Repeat the division of the new quotient by 5. 3/5 gives a quotient of 0 with remainder of 3 so we stop

Number = 3 3 1 1

Step-by-step explanation:

This is a geometric series with common ratio of 6/5
Any term is 6/5 times the previous term

The general formula for the nth term of a geometric series given the common ration r and the first term a₁ is

[tex]a_n = a_1\cdot r^{n-1}[/tex]

Here r = 6/5 and n = 10

So the 10th term is
[tex]a_{10} = 3\cdot(\dfrac{6}{5})^9[/tex]

= 3 x (6⁹/5⁹) = 3 x (10077696/1953125) = 30233088/1953125 = 15.479

Car A consumes 11.9 gallons.

Car B consumes 13 gallons

Car A consumes 16.3 gallons

Car B consumes 11.6 gallons

In order to determine the required values, the mathematical operation that would be used is division. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.

Gallons that would be consumed when driving  300 mi of city driving plus 100 mi of highway driving:

For Car A = (300 / 36) + (100 / 28) = 11.9 gallons

For Car B: (300 / 29) + (100 / 37) = 13 gallons

Gallons that would be consumed when driving  100 mi of city driving plus 300 mi of highway driving:

For Car A = (100 / 36) + (300 / 28) = 16.3 gallons

For Car B: (100 / 29) + (300 / 37) = 11.6 gallons

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Division = divide any two numbers or variable called division.

Let's consider a division problem.

5/2 → 2 + 1

Here 5 is called the dividend,2 is the divisor,2 is the quotient, and 1 is the remainder.

Now,

2  × 2 + 1 = 5

Therefore,divisor × quotient + remainder = dividend

So,

Let's suppose the divisor in the given case is x

Now,

52x + 18 ≥ 1000

52x ≥ 982

The price of the adult's ticket is $20 and the price of a child's ticket is $14.

Let adults = a

Let children = c

The appropriate equation will be:

3a + 4c = 116

2a + 3c = 82

Multiply equation I by 2

Multiply equation ii by 3

6a + 8c = 232

6a + 9c = 246

Subtract

c = 14

Price for children = 14

Since 2a + 3c = 82

2a + 3(14) = 82

2a + 42 = 82

2a = 82 - 42

2a = 40.

a = 40/2

a = 20

Therefore, the price of the adult's ticket is $20 and the price of a child's ticket is $14.
