The mechanical energy will be 100 Joules

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.

So

Mechanical energy = 60J + 40J

Mechanical energy = 100 Joules

Answer:

The correct answer option is C. 100 Joules.

Step-by-step explanation:

We are given that Greta jumps up 2 feet into the air. Her potential energy is 60 Joules while her kinetic energy is 40 Joules.

We are to calculate her total mechanical energy which will be the sum of her potential energy and her kinetic energy.

So we simply need to add the two given values of the energies.

Total mechanical energy = 60 + 40 = 100 Joules

Answer:

x = -1

Step-by-step explanation:

You can write the equation of the line by finding the slope between the points and substitute it with a point into the point slope form.

Answer:

B. 1395 square units.

Step-by-step explanation:

We have been given an octagon. We are asked to find the area of the given regular octagon.

[tex]\text{Area of octagon}=\frac{a\cdot p}{2}[/tex], where,

a = Apothem,

p = Perimeter.

Let us find apothem of octagon by multiplying 17 by 8.

[tex]\text{Perimeter}=8\times 17[/tex]

[tex]\text{Perimeter}=136[/tex]

Upon substituting our given values in area formula, we will get:

[tex]\text{Area of octagon}=\frac{20.52\times 136}{2}[/tex]

[tex]\text{Area of octagon}=\frac{2790.72}{2}[/tex]

[tex]\text{Area of octagon}=1395.36\approx 1395[/tex]

Answer:

see explanation

Step-by-step explanation:

Given

x² + 17x - 60 = 0

To factor the quadratic

Consider the factors of the constant term (- 60) which sum to give the coefficient of the x- term (+ 17)

The factors are + 20 and - 3, since

product = + 20 × - 3 = - 60 and sum = + 20 - 3 = + 17, thus

x² + 17x - 60 = (x + 20)(x - 3) = 0

Equate each factor to zero and solve for x

x + 20 = 0 ⇒ x = - 20

x - 3 = 0 ⇒ x = 3

Rearrange x + y = 11.

x = 11 - y

Substitute into other equation.

4(11 - y)^2 = 3y^2 = 8

Answer:

4(11 - y)^2 - 3y^2 = 8 (#2)

Answer:

The answer is (1, -8)

Step-by-step explanation:

The vertex of a parabola is the lowest or highest point on the parabola.

In this graph, the vertex would be the lowest point.

Answer:

6

Step-by-step explanation:

f (x)=x^2and g(x)=x+6  (I will assume you meant x not c)

The first step if to find f(0)

f(0) = 0^2 = 0

Now we find g(f(0))= g(0)

g(0) = 0+6  = 6

g(f(0) =6

If you meant c

Then g(f(0) = c+6

Answer:

311 students

Step-by-step explanation:

Let s represent the number who prefer sushi

Let p represent the number who prefer pizza

Five times the number who prefer sushi = 5s

27 fewer than (5s) = 5s - 27

P = 5s - 27

1,528 = 5s - 27

1,555 = 5s (add 27 to both sides)

311 = s (divide both sides by 5)

311 students prefer sushi to pizza.

Given that Lake Snider High School surveyed its student population about if they prefer pizza or sushi, and the students who prefer pizza represent twenty-seven fewer students than five times the number of students who prefer sushi, if 1,528 students prefer pizza, to determine how many students prefer sushi the following calculation must be performed:

Answer:

1  7/8 cups leftover

Step-by-step explanation:

The total amt. of sugar Suze needs is 5(1  1/2 cups) = 15/2 cups, or 7.5 cups.

Combining the 3  1/4 and 6  1/8 cups of sugar remaining in the bag results in 3 2/8 + 6 1/8 cups, or 9 3/8 cups total.  She needs only 7.5 cups of this sugar.

Thus, she has leftover the following amount:  9 3/8 - 7 4/8 cups, which

simplifies to  1  7/8 cups

Total C.Sugar

3 1/4+6 1/8

=13/4 + 49/8

=26/8 + 49/8

=75/8 cups

Used C.Sugar

1 1/2 × 5

= 3/2 × 5

= 15/2 cups

Remaining C.Sugar

75/8 - 15/2

=75/8 - 60/8

=15/8

=1 7/8 cups

Answer

The volume of the figure is [tex]\frac{l^{3}}{3}[\frac{1}{2}\pi-1]\ units^{3}[/tex]

Step-by-step explanation:

we know that

The volume of the figure is equal to the volume of the cone minus the volume of the square pyramid

step 1

Find the volume of the cone

The volume of the cone is equal to

[tex]V=\frac{1}{3}\pi r^{2} h[/tex]

we have

[tex]r=l\frac{\sqrt{2}}{2}\ units[/tex]

[tex]h=l\ units[/tex]

[tex]V=\frac{1}{3}\pi (l\frac{\sqrt{2}}{2})^{2}l[/tex]

[tex]V=\frac{1}{3}\pi (\frac{l^{3}}{2} )[/tex]

[tex]V=\frac{1}{6}\pi (l^{3})\ units^{3}[/tex]

step 2

Find the volume of the square pyramid

[tex]V=\frac{1}{3}Bh[/tex]

we have

[tex]B=l^{2}\ units^{2}[/tex]

[tex]h=l\ units[/tex]

substitute

[tex]V=\frac{1}{3}(l^{3})\ units^{3}[/tex]

Answer:

51 and 64

Step-by-step explanation:

The Empirical Rule states that 68% of normally distributed data lies within one standard deviation of the mean.

Hence, if the mean is 57.5, one standard dev. above that is 57.5+6.5, or 64, and one standard dev. below the mean is 57.5-6.5 = 51.

Thus,

we can conclude that 68% of the students received scores between 51 and 64.

Final answer:

Approximately 68% of the eighth-grade students received scores between 51 and 64.

Explanation:

In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean. So, in this case, 68% of the eighth-grade students received scores between the mean of 57.5 minus one standard deviation of 6.5 and the mean plus one standard deviation.

Calculating the range:

Therefore, we can conclude that approximately 68% of the students received scores between 51 and 64.

Answer: [tex]40cm^2[/tex]

Step-by-step explanation:

A cross-section is the shape that results of the intersection of a plane with an abject.

When the cone is sliced by a plane perpendicular to the base and passes through the vertex, the cross-section obtained is a triangle.

The area of the triangle can be calculated with the formula:

[tex]A=\frac{b*h}{2}[/tex]

Where the base of the triangle is b and its height is h.

The base of the triangle is the diameter of the cone. Knowing the radius, the diameter is:

[tex]diameter=2*radius\\diameter=2*4cm\\diameter=8cm[/tex]

Then:

[tex]b=8cm[/tex]

The height ot this triangle is the height of the cone:

[tex]h=10cm[/tex]

So, by substituting into the formula you get the area of the cross-section in square centimeters:

[tex]A=\frac{(8cm)(10cm)}{2})=40cm^2[/tex]

The simplified equivalent expression for 6(7-3y)+6(y+1) is -12y+48.

To simplify to create an equivalent expression for 6(7-3y)+6(y+1), we first distribute within the parentheses.

This gives us: 42-18y+6y+6.

Next, we combine like terms (-18y and 6y; 42 and 6) to get -12y+48.

So, the simplified equivalent expression is -12y+48.
