Answer: 51.5 inches

Step-by-step explanation: The high jumper will be making seven jumps, increasing by 1/2 inch each time. In order to calculate how much it will be moved up from the original position we need to multiply 1/2 x 7 jumps = 3.5 inches. In order to calculate how high the bar will now be, we need to add together the original 48 inch height plus the 3.5 inches that it was been raised, so they total is 51.5 inches high.

Answer:

2. y - (-5) = -3 (x - 5)

3. y = -5/2

Step-by-step explanation:

Point intercept form: y - y₁ = m (x - x₁)

Where y and x are just kept as y and x, y₁ and x₁ are the parts of a coordinate, and m = slope.

2. The points are (5, -5) and the slope is -3. Plug this into y - y₁ = m (x - x₁) to get

y - (-5) = -3 (x - 5)

3. As stated, parallel lines have the same slope, so the slope of the line would be -5/2. The origin is (0, 0), so plug these two numbers in.

y - y₁ = m (x - x₁)

y - 0 = -5/2 (x - 0)

y = -5/2

Answer:

72cm

Step-by-step explanation:

The volume of the base of a right square pyramid is 72 cubic centimeters, the option second is correct.

It is given that the perimeter of the base of a right square pyramid is 24 cm and the height of the pyramid is 6 cm.

It is required to find the volume of the right square pyramid.

It is defined as a three-dimensional space enclosed by an object or thing.

We know the formula for finding the volume (V) of a right square pyramid is:

[tex]\rm V= a^2\times\frac{h}{3}[/tex]    Where a is the base side and h is the height of the right square pyramid.

[tex]\rm The \ perimeter \ of \ the \ base \ of \ a \right \ square \ pyramid = 4\times(side)[/tex]

[tex]\rm 24 = 4a\\\rm a=6 \ cm[/tex]

And h = 6 cm, putting this value in the above volume formula, wet get:

[tex]\rm V= (6)^2\times\frac{6}{3} \\\rm V= 36\times 2\\\rm V=72 \ cm^3[/tex]

Thus, the volume of the base of a right square pyramid is 72 cubic centimeters, the option second is correct.

Answer:

a < 9/20

Step-by-step explanation:

Our equation is the following: ax^2 + 3x + 5

a = unknown

b = 3

c = 5

We are concerned with the discriminant. Namely, b^2 - 4ac must be greater than 0 if we want to real roots

Lets plug in the values:

9 - 4a(5) > 0

9 - 20a > 0

9 > 20a

9/20 > a

a < 9/20

In a quadratic equation given as,

ax² + bx + c = 0

Discriminant of the equation → (b² - 4ac)

For the roots of the equation,

Given quadratic equation in the question is,

ax² + 3x + 5 = 0

Coefficient of x² = a

Coefficient of x = b = 3

Constant term = c = 5

If the roots of this equation are real,

b² - 4ac > 0

(3)² - 4a(5) > 0

9 - 20a > 0

20a < 9

a < [tex]\frac{9}{20}[/tex]

Therefore, for all values of 'a' less than [tex]\frac{9}{20}[/tex], equation will have two real roots.

Answer:

The total number of possible outcomes if the code has 3 letters is 64

Step-by-step explanation:

The keypad has only the letters A-D, that is, A,B,C,D.

To calculate the total number of possible outcomes if the code has 3 letters,

let these spaces represent the code _ _ _

For the first space, there are 4 possibilities (since we have 4 letters)

For the second space, we also have 4 possibilities (since there is no restriction on repetition)

Also, we have 4 possibilities for the last space.

Hence, the total number of possible outcomes if the code has 3 letters is 4×4×4 = 4³ = 64.

There are 64 total possible outcomes if the code has 3 letters

The number of letters is given as:

n = 4

The code makes use of three letters.

This means that:

So, the number of possible outcomes is:

Outcomes = 4 * 4 * 4

Evaluate the product

Outcomes = 64

Hence, there are 64 total possible outcomes if the code has 3 letters

Answer: D. -0.6

Step-by-step explanation:

Z score formula= x-mean/ SD

34-40/10= -3/5= -0.6

The standardized score for a tree that is 34 years old is -0.6

We have given that,

The age of trees in a forest is approximately normal with an average age of 40 years and a standard deviation of 10 years.

We have to determine what is the standardized score for a tree that is 34 years old

Z score formula= x-mean/ SD

We use the given values in the above formula so we get,

Z score =34-40/10

Z score = -3/5

Z score = -0.6

Answer:

Option (4)

Step-by-step explanation:

Input values are always represented by the x values and output values of a function is represented by f(x).

From the table given,

Values under x column are the input values and values under f(x) or gx) column are the output values.

From both the tables, common output values for the same input value (x = 1) are,

f(1) = 3

g(1) = 3

Therefore, Option (4) is the answer.

The input value that produces the same output value for both functions is: D. x = 1

A function is a relation which has exactly one y-value (output value) that corresponds to each x-value (input value) in the relation.

In the function [tex]f(x)[/tex], the input value (x) 1 produces an output value [tex]f(x)[/tex] of 3. Same applies for the function g(x).

Thus, [tex]f(1) = g(1) = 3[/tex]

Therefore, the input value that produces the same output value for both functions is: D. x = 1

Answer:

ave. val. = -------------- = 0

Step-by-step explanation:

That's y = 2x^4 (the ^ symbol indicates exponentiation).

The average value of a function f(x) over the interval [a, b] is

                    f(b) - f(a)  

ave. val. = ----------------

                       b - a

Here a = -2, b = 2 and f(x) = 2x^4.  Thus, f(a) = 2(-2)^4 = f(b) = 2(2)^4 = 32, and

the average value is:

                  32 - 32

Marco plotted the following points on the number line.

Point A: 0.3 Point B:  3/4 Point C: 11/4 Point D: 0.7

Which point did he plot incorrectly?

Answer:

Point D

Step-by-step explanation:

Given

[tex]Point\ A= 0.3[/tex]

[tex]Point\ B= \frac{3}{4}[/tex]

[tex]Point\ C= \frac{11}{4}[/tex]

[tex]Point\ D= 0.7[/tex]

Required

The incorrectly plotted point

Number plotted on a number line increases from left to right. This implies that:

[tex]A < B < C < D[/tex]

Substitute the values for the given points

[tex]0.3 < \frac{3}{4} < \frac{11}{4} < 0.7[/tex]

Express as fractions

[tex]0.3 < 0.75 < 2.75 < 0.7[/tex]

Up till 2.75, the order of the numbers is correct.

However, 0.7 is less than 0.75 and 2.75

So, 0.7 is not placed correctly.

This implies that point D is not correctly placed

Answer:

Angle BAC = 62.35

Step-by-step explanation:

Here, we want to get the angle marked BAC

From the diagram, we have the angle ABC as 90

This is because angle at the center is twice the angle at the circumference

Furthermore, using the arc angle relationship;

angle ACB is half arc AB

so ACB angle is 55.3/2 = 27.65

mathematically;

Angle BAC + 27.65 + 90 = 180

This is because sum of angles in a triangle is 180

Thus;

angle BAC = 180-90 - 27.65

angle BAC = 62.35

Answer:

289feet²

Step-by-step explanation:

Area of a rectangle = length x breadth

area of a square = length²

area of the yard that is not covered by the hot tub and fire pit =

Area of the yard - (area of the hot tub + area of the fire pit)

Area of the yard = 20 feet² = 400 feet²

area of the hot tub =  6 feet² x 8 feet² = 48 feet²

area of the fire pit = 7 feet² x 9 feet² = 63 feet²

400 - (48 + 63) = 289 feet²
