You can use the formula A = 252 + 4sh to find the surface area of a square prism
that has a base with edge length s and height h. A square prism has a base with
edges that are 12 centimeters long and a height of 15 centimeters. What is the
surface area of the square prism? Show your work.
Please answer fast!! I’m in a test. Give the full explanation

Answers

Answer:

The surface area is 972 square cm

Step-by-step explanation:

Numeric Value of Functions

Given the function:

A = 252 + 4sh

Where A is the surface area of a square prism , s is edge length of the base  h is the height.

A square prism has a base with edges s=12 cm long and height of h=15 cm.

Substituting these values, we get:

A = 252 + 4(12)(15)

A = 252 + 720 = 972

A = 972

The surface area is 972 square cm

The surface area of the square prism is 1008 cm².

Surface area of a square prism:

Surface area = 2s² + 4sh

where

s = edge side

h = height

Therefore,

s = 12 cm

h = 15 cm

surface area = 2 × 12² + 4 × 12 × 15

surface area = 2 × 144 + 48 × 15

surface area = 288 + 720

surface area = 1008

surface area = 1008 cm²

A man flies a small airplane from Fargo to Bismarck, North Dakota- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1.2 hours. What is the planes speed in still air, and how fast is the wind blowing?
1) His plane speed equals ______ mph
2) The wind speed equals ______ mph

Answers

Answer:

1.) 120 mph

2.) 30 mph

Step-by-step explanation:

Given that a  man flies a small airplane from Fargo to Bismarck, North Dakota- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1.2 hours. What is the planes speed in still air, and how fast is the wind blowing?

Let the wind speed = w

and the plane speed = p

From the first sentence,

P - w = 180/ 2

P - w = 90 ....... ( 1 )

From the second statement,

P + w = 180/1.2

P+ w = 150 ...... ( 2 )

Solve equation 1 and 2 simultaneously

P + w = 150

P - w = 90

Add the two equations

2P = 240

P = 120 mph

Substitute p in equation 1

W = 150 - 120

W = 30

Therefore, the wind speed is 30 mph and the plane speed is 120 mph

2. The table shows monthly rainfall in inches for
five months. Identify the outlier in the data set.
Determine how the outlier affects the mean,
median, and mode of the data. Then tell which
measure of center best describes the data with
and without the outlier. Round to the nearest
hundredth. Justify your selection.

Answers

okay, first to figure out the IQR of the table you need to organize them from least to greatest.

2.43, 6.14, 6.47, 7.19, 8.38, 8.63

to find the middle number of all of these you add them all together and divide by 6, which is the total amount of numbers there.

2.43 + 6.14 + 6.47 + 7.19 + 8.38 + 8.63 = 39.24

39.24 / 6 = 6.54

now that we have the IQR, next we find the outlier. to find the outlier you multiply the IQR by 1.5 which is 6.54 x 1.5 = 9.81 <- outlier

Outliers affect the mean value of the data but have little effect on the median or mode of a given set of data.

2.43 + 6.14 + 6.47 + 7.19 + 8.38 + 8.63 + 9.81 = 49.05

49.05 / 7 = 7.00 (Rounded)

Answers

Answer:

It’s (-9,-4)

Step-by-step explanation:

Edge

The focus of the graph of the function is located at (−9,−4).

Given that, the graph of y²+ 8y – 4x – 24 = 0 is a parabola. We need to find where is the focus located.

What is vertex form?

The vertex form of an equation is an alternate way of writing out the equation of a parabola. Normally, you'll see a quadratic equation written as ax²+bx+c, which, when graphed, will be a parabola.

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Direction: Opens Right

Vertex: (−10, -4)

Focus: (-9, -4)

Axis of Symmetry: y=−4

Directrix: x=−11

Therefore, the focus of the graph of the function is located at (−9,−4).

AE is an angle bisector of BAC if the measure of BAE = x + 30 and masure of angle EAC = 3x-10 determine Measure of angle EAC

Answers

The measure of angle EAC is equivalent to 50 degrees.

The value of x for the given geometry will be 20°.

What is an angle?

The angle is the measurement of the angular distance. For instance, we have a meter and an inch for linear motion, but we don't have a measurement for angular rotation, therefore the angle is helpful in determining angular rotation.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Given that AE is a bisector of ∠BAE and ∠EAC

so,

∠BAE = ∠EAC

x + 30 = 3x - 10

x = 20°

Hence 20° will be the answer to the given question.

A number system is defined as a system of writing to express numbers.

We need to find the  distance between point A and point C on the number line.

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

The length along a line or line segment between two points on the line or line segment is known as distance.

The point A is at -3.

The point C is at 7

Now the distance between A and C is AC.

AC=OC-OA

=7-(-3)

=7+3

The center of a circle is located at the point (1,1). The point (6,3) is located on the circle.

What is the radius of the circle?​

Answers

Answer:

Square root of 29

Step-by-step explanation:

The required radius of the circle would be √29 units which circle with a center at (1, 1) and a point on the circle is (6, 3).

What is the equation of a circle?

The equation of a circle with center (h,k) and radius r is :

r² = (x−h)² + (y−k)²

Given that a circle with a center at (1, 1) and a point on the circle is (6, 3).

Since the circle passes through points (6, 3),

So the radius (r) of the circle is the distance between points (1, 1) and (6,3).

⇒ r² = (6 - 1)² + (3 − 1)²

⇒ r² = (5)² + (2)²

⇒ r² = 25 + 4

⇒ r² = 29

⇒ r = √29

Therefore, the required radius of the circle would be √29 units.
