Step-by-step explanation:

Answer:

C

Step-by-step explanation:

It passes the vertical line test

the vertical line test is taking a vertical line and putting it anywhere on the graph, and if it passes 2 points, it fails, and since if you put the line anywhere, it only passes one point of the parabala, so it passes the line test

Answer: C

Step-by-step explanation: The easiest way to determine if a

relation is a function is to use the vertical line test.

The vertical line test tells us that if we can draw a vertical line

that intersects more than one point on the graph of a relation,

then the relation is not a function.

However, in this case, notice that there is no way to draw a

vertical line that intersects more than one point on the graph.

Therefore, this relation must be a function.

Step-by-step explanation:

Answer:

B) 6

Step-by-step explanation:

they make one stop every 150 miles

900/150 = 6 stops

The family will make 6 stops for a trip of 900 miles.

So, the answer is B. 6.

Given is table showing number of stops made and the number of miles the family traveled.

The number of times the family stops to rest during a trip is dependent upon the number of miles the family travels.

We need to determine the number of stops the family will make for a trip of 900 miles.

To predict the number of stops the family will make for a trip of 900 miles, we can observe the pattern in the given data.

From the table, we can see that the number of stops is increasing by 1 for every 150 miles traveled.

So, to find the number of stops for 900 miles, we can divide 900 by 150 and round up to the nearest whole number since the number of stops cannot be a fraction.

900 miles / 150 miles = 6

Therefore, the family will make 6 stops for a trip of 900 miles.

So, the answer is B. 6.

Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Step-by-step explanation:

The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-

[tex](n-2)\times180^{\circ}[/tex]

Given: The sum of the measures of the interior angles of a polygon is 1920°.

i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]

[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]

But number of sides cannot be in decimal.

Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.

Step-by-step explanation:

cost of T- shirts = 125 (Fixed price) + 15* number of T- shirts

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

A school pays a company $125 to design gym T-shirts.

It costs an additional $15 to make each T-shirt.

Number of T-Shirts         Cost ($)

             0                             125

              5                            200

              10                           275

              15                           350

b) equation:

    cost of T- shirts = 125 (Fixed price) + 15* number of T- shirts

c) cost of  378 T- shirts

    =125+ 15(378)

    = 5795

c) school store has a budget of $2345

    Number of T- shirts = (2345-125)/15

                                      = 148 T- shirts

Answer:

a) The volume of the sphere is approximately 14,137.16694 which is 14,140 cm³ correct to 4 significant figures

b) The volume of water required to fill the tank is approximately 103,670 cm³

Step-by-step explanation:

a) In the question, the radius of the sphere, r = 15 cm

The formula for the volume, 'V', of a sphere is given as follows;

[tex]V = \dfrac{4}{3} \times \pi \times r^3[/tex]

Where;

r = The radius of the the sphere

V = The volume of the sphere

Plugging in the value for the radius, 'r', of the sphere, in the equation for, 'V', we get;

[tex]V = \dfrac{4}{3} \times \pi \times 15^3 \approx = 14,137.16694[/tex]

Therefore;

The volume of the sphere to 4 significant figures is V ≈ 14,140 cm³

b) The parameters of the cylindrical tank are;

The height of the cylindrical tank, h = 60 cm

The radius of the cylindrical tank, r = 25 cm

The volume of a cylinder, V = π·r²·h

∴ The volume of the cylindrical tank without water, '[tex]V_t[/tex]', is given as follows;

[tex]V_t[/tex] = π × (25 cm)² × 60 cm ≈ 117809.72451 cm³

The volume of water, [tex]V_{water}[/tex], required to fill the tank with the sphere of volume 'V' placed inside is given as follows

[tex]V_t[/tex] = V + [tex]V_{water}[/tex]

∴ [tex]V_{water}[/tex] = [tex]V_t[/tex] - V

From which we get;

[tex]V_{water}[/tex] ≈ 117809.72451 cm³ - 14,140 cm³ = 103,669.72451 cm³ ≈ 103,670 cm³

The volume of water required to fill the tank, [tex]V_{water}[/tex] ≈ 103,670 cm³.

Answer:

2 docenas cuestan $61.200.

Step-by-step explanation:

Para encontrar la respuesta, debes considerar que una docena equivale a 12 artículos, por lo cual tienes que multiplicar 12 por 2 para encontrar el número de rosas en 2 docenas:

12*2=24

Ahora, dado que sabes que una rosa cuesta $2.550 tienes que multiplicar este valor por 24 para encontrar cuanto cuestan 2 docenas:

$2.550*24=$61.200

De acuerdo a esto, la respuesta es que 2 docenas cuestan $61.200.

The coordinates after the reflection will be C' = (-4, 8), D' = (-2,4), E' = (6,3), and F' = (4, 7).

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that, Parallelogram CDEF with vertices C(-4,-4), D(-2, 0), E(6, 1), and F(4, -3) in the line y = 2.

The following coordinates are obtained after reflection in the line y = 2.

C' = (-4, 8)

D' = (-2,4)

E' = (6,3)

F' = (4, 7)

Thus, the coordinates after the reflection will be C' = (-4, 8), D' = (-2,4), E' = (6,3), and F' = (4, 7).

Answer:

[tex]10^{4.876}=y[/tex]

Step-by-step explanation:

Logarithms are just another way of arranging an exponential equation! You know how you can rearrange the equation 2 + 3 = 5 as 5 - 3 = 2, or the equation 2 x 3 = 6 as 6 ÷ 3 = 2? With logarithms, you can do the same thing with an equation like 2³ = 8. As a logarithm, we would write this equation as log₂(8) = 3. Here, we call 2 the base, 8 the argument, and 3 the exponent.

Logarithms like the one in the problem with a base of 10 are just written as log, without the base written out. In the equation log(y) = 4.876, our base is 10, our argument is y, and our exponent is 4.876, so as an exponential equation, we would write it as

Carlos works for 8 hours and 55 minutes.

Given that, Carlos starts work at 21:20 and finishes at 06:15 the next day.

A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.

The 24-hour clock is more often shown on digital clocks and is written in a 4-digit form, with the first two digits representing the hour and the last two representing the minutes.

From 21:20 to 06:15 there are 8 hours and 55 minutes.

Therefore, Carlos works for 8 hours and 55 minutes.

Step-by-step explanation:

A 15 watt night light would keep up to lit for 33.33 hours.

Energy in simple definition can be defined as the ability to do work. Energy can be converted into various forms and can be used to do the work.

The formula for calculating energy is,

Energy = Power × Time

Given that energy of one jelly filled donut contains an amount of energy equal to 0.5 kilowatt hours.

1 kilowatt = 1000 watts

0.5 kilowatt hour = 500 watts hour

Now this energy is converted into electrical energy and used it to lit 15 watt night light.

Power of the light = 15 watts

Energy = 500 watts hour

Time = Energy / Power

        = 500 / 15

        = 33.33

Hence 15 watt light will lit for 33.33 hours.
