The graph below shows the height of an object that has been launched off a 50-foot-high wall. Appropriate what is the maximum height the object reaches?
a. 50 feet
b. 150 feet
c. 106 feet
d. 4.4 feet

Answer:

62.8 inches

Step-by-step explanation:

✓We can determine the

Circumference of the wheel of the bicycle using the expression below;

Circumference= (πd) ...........eqn(1)

Where d= diameter = 20inches

If we substitute the value of " diameter" into eqn(1)

Circumference = (π × 20)

= 62.8inches

(Where π= 3.142)

Therefore, measurement that is closest to the circumference of the wheel is 62.8inches

Step-by-step explanation:

If you double all of the dimensions of a rectangular prism, you create a similar prism with a scale factor of 2. The surface area of the similar prism will increase as the square of the scale factor (22 = 4) and the volume will increase as the cube of the scale factor (23 = 8).

Given:

The graph of a parabola.

To find:

The domain, range and check whether it is a function or not.

Solution:

Domain: The set of x-values or input values is known as domain.

Range: The set of y-values or output values is known as range.

A relation is a function if their exist unique outputs for each input. In other words a graph is a relation if it pass the vertical line test.

Vertical line test: Each vertical line intersect the graph at most once.

The given function is defined for all real values of x which are greater than or equal to -3. So, the domain of the given graph is:

[tex]Domain=[-3,\infty)[/tex]

The given function values can be any real number. So, the range of the given graph is:

[tex]Range=(-\infty,\infty)[/tex]

For x=0, we have two values of the function because the graph intercept the y-axis at two points.

Since the graph does not pass the vertical line test therefore the given graph is not a function.

Step-by-step explanation:

Answer:

The reasonable domain for the scenario is option 'a';

a) [0, 7]  

Step-by-step explanation:

For the projectile motion of the object, we are given;

The speed at which the object is launched, v = 29.4 meters per second

The height of the platform from which the object is launched, h = 34.3 meter

The equation for the height of the object as a function of time 'x' is given as follows;

f(x) = -4.9·x² + 29.4·x + 34.3

The domain for the scenario, is given by the possible values of 'x' for the function, which is found as follows;

At the height from which the object is launched, x = 0, and f(x) = 34.3

At the ground level to which the object can drop, f(x) = 0

∴ f(x) = -4.9·x² + 29.4·x + 34.3 = 0

-4.9·x² + 29.4·x + 34.3 = 0

By the quadratic formula, we have;

x = (-29.4 ± √(29.4² - 4 × (-4.9) × 34.3))/(2 × (-4.9)

∴ x = -1, or 7

Given that time is a natural number, we have the reasonable domain for the scenario as the start time when the object is launched, t = 0 to the time the object reaches the ground, t = 7

Therefore, the reasonable domain for the scenario is; 0 ≤ x ≤ 7 or [0, 7].

Answer:

0.03906square foot

Step-by-step explanation:

Given the dimension of the bedroom yo be 2.25in by 2.5in

First we need to convert to foot

2.25in = 0.08333×2.25 = 0.1875feet

2.5in = 0.08333×2.5 = 0.2083feet

Area of the rectangular bedroom = length × width

Area of the rectangular bedroom = 0.1875×0.2083

Area of the rectangular bedroom = 0.03906square foot

Step-by-step explanation:

Well according to the picture (it doesn't have the full problem so this is what I can explain):

To make 1 dozen cupcakes (x), you need 1 cup of butter (y). (Or you can see in the question on the picture: y = 0.5x)

So let's say, he wants to make half a dozen cupcakes, he would need 0.5 cups of butter. How many cups of butter he uses is how many dozens he can make.

Answer:

Answer:

True

Step-by-step explanation:

She actually earned 21 credits, which means she earned at least 4.

Lauri earned 4 credits for the year is false.

A division is a process of splitting a specific amount into equal parts.

To earn one Social Security credit, a person needs to earn a certain amount of money each year.

The amount needed for one credit changes each year and is determined by the Social Security Administration.

Given that last year Lauri earned $23,000 and earned 4 credits, we can calculate how much money she earned per credit by dividing her total earnings by the number of credits earned:

$23,000 / 4 credits = $5,750 per credit

Now we can check if $5,750 is equal to $1,090, the amount needed for one credit according to the problem.

$5,750 is not equal to $1,090, so the statement is false.

Hence,  Lauri earned 4 credits for the year is false.

Answer:

Guido tiene 9 años, Andrés tiene 36 años y David tiene 3 años.

Step-by-step explanation:

Con la información proporcionada, sabes que la edad de los tres suma 48, lo que se puede expresar como:

x+y+z=48, donde:

x es la edad de Guido

y es la edad de Andrés

z es la edad de David

Además, de acuerdo al enunciado puedes decir que la edad del papá Andrés es cuatro veces la edad de Guido y que la edad de David es la tercera parte de la edad de Guido y puedes escribir las siguientes ecuaciones:

y=4x

z=x/3

Ahora puedes reemplazar estas dos ecuaciones en la primera y despejar x:

x+4x+x/3=48

5x+x/3=48

16x/3=48

16x=48*3

16x=144

x=144/16

x=9

Después, puedes reemplazar el valor de x en y=4x para encontrar el valor de y:

y=4x

y=4*(9)

y=36

Finalmente, debes reemplazar el valor de x en z=x/3 para encontrar el valor de z:

z=x/3

z=9/3

z=3

De acuerdo a esto, Guido tiene 9 años, Andrés tiene 36 años y David tiene 3 años.

Answer:

339n in^3

Step-by-step explanation:

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

Water in the cylinder = volume of cylinder - volume of sphere

volume of a cylinder = nr^2h

n = 22/7

r = radius = 10/2 = 5

n x (5^2) x 15 = 375 in^3

volume of a sphere = (4/3) x (n) x (r^3)

n = 22/7

r = 6/2 = 3

(4/3) x (n) x (r^3) =  36n

Step-by-step explanation: I used a protractor

Answer:

35 degrees.

Step-by-step explanation:

To figure this question out, we first need to understand how to solve it. We know that all the angles in a triangle add up to 180 degrees. we can imagine this is a massive triangle. We can do the following

73 + 51 + (21+x) = 180

we can do this, because we already know the other two angles, and we know part of the last angle is 21, and the other part of the last angle is x. We can add them all together.

124 + 21 + x =180

145 + x =180

35 = x

To do this, we simply consider the intervals of the hair lengths where they are lots of data; i.e. where frequency is greater than 1

For the first cluster, we can select the following interval

[tex]\frac{1}{2} \to 2[/tex]

Because;

hair length [tex]\frac{1}{2}[/tex] has a frequency of 3

and the data continues till hair length 2 which has a frequency of 2

For the second cluster, we can select the following interval

[tex]3\frac{1}{2} \to 4\frac{1}{2}[/tex]

Because;

hair length [tex]3\frac{1}{2}[/tex] has a frequency of 3

and the data continues till hair length [tex]4\frac{1}{2}[/tex] which has a frequency of 2

Note that, hair lengths with 0 or 1 as their frequency were not selected as part of the cluster
