If a triangle was rotated about the y-axis, as seen in the picture below, what 3-d shape would be created

Answer:

(x+5) (x+5) - 3

Step-by-step explanation:

i dont know the answer nor the step by step explanation

The equation by making one change in the equation of f(x) so that the graph has no x-intercepts will be f(x) = (x + 5)(x + 5) - 3.

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

The parabolic equation is given below.

f(x) = (x+5)² - 3

Then the solution to the equation will be

         f(x) = 0

(x+5)² - 3 = 0

    (x+5)² = 3

     x + 5 = ±√3

           x = - 5 ±√3

The graph is given below.

Answer:

Median- 12

Q1- 5

Q3- 43

IQR- 38

Step-by-step explanation:

2, 5, 11, 13, 43, 45

Put your numbers in order of least to greatest

Since there is no given median as the amount of numbers is even, find the number in between the 2 middle numbers, in this case, the number would be 12, as it is in between 11 and 13.

To find Q1 and Q3, you need to find the first and third median, which would be 5 and 43. To find the IQR, you need to subtract Q3 from Q1, which would give you 38 in this equation

Answer:

20%

Step-by-step explanation:

The formula to find percent error is the absolute value of the actual value (60) minus the approximate value (48) divided by the actual value (60) times 100. So first we calculate 60 - 48 which is 12 then divide 12 by 60 which gives us 0.2 and finally multiply by 100 which gives us the answer of 20%

Answer:

Answer:

30/182 = 15/91.

Step-by-step explanation:

PROBABILITY: the likelihood of an event.

There are a total of 14 shirts in the basket.

Of the 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.

The probability of picking a black shirt is 6 in 14, or 6/14.

The probability of picking a white shirt is 8 in 14, or 8/14.

WITHOUT REPLACING: This means that you take one without putting it back. (There will be one less).

6/14 × 5/13 = 30/182.

30/182 = 15/91.

The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back is 15/ 91.

Probability refers to a possibility that deals with the occurrence of random events.

There are a total 14 shirts in the basket.

Out of the total of 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.

The probability of picking a black shirt = 6/14.

The probability of picking a white shirt = 8/14.

The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back

= 6/14 × 5/13

= 30/182.

= 15/91.

Answer: 0.32

Step-by-step explanation:

Answer:

fixed amount is 150

the rate is 6

The formula to calculate the total cost of the caterer is

total cost = 150 × 6 + number of students

Step-by-step explanation:

1. 1050= 150×r+f

2. 750= 100×r+f

• On number 2 you substract on both sides f so you get 750-f=100×r with this you divide on both sides 100 and you get 7,50 -f÷100=r

• Now you can put r into term of number 1 and you get 1050=150x(7,50-f÷100)+f

• If you calculate this to just get a f on one side you get f=150 so this the fixed amount

• Put f in r=7,50-f÷100 so u get r=7,50-150÷100 or r=6 this the rate

• So the formula to calculate the total cost for the caterer is

total cost=150 + 6 × number of students

Step-by-step explanation:

Answer:

The octagon is regular, all of its sides and angles are congruent. Thus, the measure of each angle is equal to the sum of its angles divided by 8. Therefore, each angle in the polygon has a measure of 1080/8 =135 degrees.

The name of the polygon is, ''Octagon.''

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Formula for sum S of n interior angles of n sided polygon is,

S = (n - 2) × 180°

Since, polygon is regular all its interior angles is same, sum of them is 135 degree times n

So, we have S = 135°n

As per formula,

S = (n - 2) × 180°

135n = (n - 2) × 180°

180n - 360 = 135n

180n = 135n + 360

180n - 135n = 360

45n = 360

n = 8

Hence, The name of the polygon is, ''Octagon.''

Answer:

Reduction

Step-by-step explanation:

So, lets go over what we know:

The black rectnagle is the orginal shape.

The organe rectnalge is the new shape.

The organge rectangle is smaller than the black rectangle.

The rogane rectangle is a scaled image of the black rectangle.

So, enlargment is when a object has a scale factor that makes it bigger than the orgninal object.

Reduction, on the other hand, is when a object has a scale factor that makes it smaller than the orginal object.

As we can see, the organe rectnagle is much smaller than the black rectnalge.

So this must be reduction, since the organe rectangle has a small scale factor that causes the shape to shrink in size.

Hope this makes sense and helps you! :)

Answer:

25/8

Step-by-step explanation:

The question can be interpreted as

Y= k/x^2.......eqn(1)

Where k= constant if proportionality

y = 1/8 when x = 1,

Substitute, we have

1/8= k/(1)^2

1/8= 1/k

Cross multiply

K= 1/8

find y when x = 5

From eqn(1)

Y= k/x^2

Y= (1/8)/(5)^2

Y=1/8 ×25

Y= 25/8

Answer: B

Step-by-step explanation:

The requried value of x in the triangle ABC is 4. Option B is correct.

In geometry, two figures are congruent if they have the same shape and size, and all their corresponding parts (sides, angles, and vertices) are congruent. Congruent figures can be moved, rotated, or reflected without changing their shape or size.

Since the given triangle ABC and EDF are congruent triangles,
So,
BC = EF
6x - 1 = 23
x = 4

Thus, the requried value of x in the triangle ABC is 4. Option B is correct.
