Answer:

A) T'(-3, 6) and V'(0, 3)

Step-by-step explanation:

In the picture attached, triangle TVW is shown.

Transforming points T and V according to the rule (x,y) -> (3/4x, 3/4y), we get:

T(-4, 8) -> (-4*3/4, 8*3/4) -> (-3, 6) which corresponds to T'

V(0, 4) -> (0*3/4, 4*3/4) -> (0, 3) which corresponds to V'

The coordinates of the endpoints of the segment T'V are; T'(-3, 6) and V'(0, 3)

According to the question;

The given triangle TVW is dilated according to the rule D (3/4)(x,y)=((3/4)x, (3/4)y) to create the image triangle T'V"W", which is not shown.

From the attached image; the coordinates of endpoints T and V are;

Answer:

x = 4

Step-by-step explanation:

It is stated that f(x) passes through

(-3, 3), (0, 3), (4, 3)

and g(x) passes through

(-4, -3), (0, 0), (4, 3)

Therefore, both functions pass through (4, 3). That is, the input value x = 4 produces the same output value y = 3 for the two functions.

Answer:

B. and D.

Step-by-step explanation:

We have that an equilateral triangle is a regular polygon, that is to say, it has its three equal sides.In traditional Euclidean geometry, the equilateral triangles are also equiangular, that is, the three interior angles are equal and measure 60 °. By symmetry of the equilateral triangle, we have to:

Any two equilateral triangles are similarly congruent, therefore:

B. Two segments that are both congruent to a third segment must be congruent to each other

 and D. All of the radio of a circle are congruent, are the correct answers.

Answer:

D. 7 h 15 min

Step-by-step explanation:

1. Convert 9:15 a.m. Eastern Time to Pacific Time. As you can see by the information given, Eastern Time is 3 hours ahead of Pacific Time. So, 9:15 a.m. Eastern Time is 6:15 a.m. Pacific Time.

2. Find the difference between 1:20 p.m. and 6:15 a.m.

1:20 p.m. = 13:20 p.m.

Answer:

y= -2/5 and y=1

Step-by-step explanation:

Start by transforming the equation to your liking:

[tex]5y^2-2=3y\\5y^2-3y-2=0\\[/tex]

Now we have to factor! To do this we have to find common numbers. Do this by multiplying -2 and 5 to get -10. Now think about which two numbers add multiply to be -10 but also add up to be -3 (I got this number from the middle of the equation). The two numbers you should've got are -5 and 2.

Now substitute those two number in place of the middle term, which is -3y like so:

[tex]5y^2-5y+2y-2 =0[/tex]

Now solve the equation in pieces... find the greatest common factor from [tex](5y^2-5y)[/tex] and the greatest common factor from [tex](2y-2)[/tex] . The two common factors for both of those are 5y and 2. Your equation should now look like this:

[tex]5y(y-1)[/tex] + [tex]2(y-1)[/tex]

The two greatest common factors become into one group and the other equation that they have in common (y-1) is it's own equation:

[tex](5y+2)(y-1)=0[/tex]

Now equal both of the equations to 0 and solve for y to get both of the values of y.

Answer:

6 minutes more

Step-by-step explanation:

Time = Distance ÷ Speed

Time = 30miles ÷ 60mph

Time = 30mins

Time = 30miles ÷ 50mph

Time = 36mins

36mins - 30mins = 6mins difference

Answer: 6 minutes

Step-by-step explanation:

Time = Distance / speed

When speed is 60 mph

Time = 30/60 = 1/2 hour = 30 minutes

When speed is 50 mph

Time = 30/50 = 3/5 hour = 36 minutes

Answer:

72 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here h = 6 , a = 15, b = 9 , thus

A = [tex]\frac{1}{2}[/tex] × 6 × (15 + 9) = 3 × 24 = 72 cm²

Answer:

= 72 cm²

Step-by-step explanation:

A = (b + B)×h/2

= (9cm + 15cm)×6cm/2

= 24cm×3cm

= 72 cm²

Answer:

y ≠ 0

Step-by-step explanation:

y ≠ 0

to determine a rational number, the denominator must not be zero.

The values of the variable 18/y are defined for all the values of y, such that y is the element of real numbers (R), y ≠ 0

A function is defined as the relationship between a specific set of inputs assigned to one output each.

In order to determine if a function is defined, we need to determine the values that make the function undefined and eliminate it.

From the given information:

Therefore, we can conclude that 18/y is defined for all the values of y, such that y is the element of real numbers (R), y ≠ 0

Answer:

d

Step-by-step explanation:

Let m = number of miles.

Each mile costs $2.35, so m miles cost 2.35m.

The flat fee is $2.

The total cost is

2.35m + 2

He can spend no more than $47, so he can spend $47 or less,

2.35m + 2 <= 47

Answer:

The additive inverse of the polynomial  being subtracted is -0.612-8+181

Step-by-step explanation:

Given expression : (1.32 +0.412 – 241) – (0.612 + 8 - 181)

Now the polynomial being subtracted : (0.612 + 8 - 181)

Additive inverse : The number in the set of real numbers that when added to a given number will give zero.

So, Additive inverse of 0.612 = -0.612

Additive inverse of 8 = -8

Additive inverse of -181 = 181

So, The additive inverse of polynomial being subtracted : -0.612-8+181

So, Option B is true

Hence the additive inverse of the polynomial  being subtracted is -0.612-8+181

As x→∞, f(x)→∞ is correct, also As x→−∞, f(x)→−∞.

Step-by-step explanation:

This function is a simple modification of the basic function y = x^3, which goes to infinity in Quadrant I as x increases, and to negative infinity in Quadrant II as x decreases.  As x→∞, f(x)→∞ is correct, also As x→−∞, f(x)→−∞.

The same end behavior applies to f(x) = 54x^3.

Answer:

22.5

Step-by-step explanation:

Since 13.5 is 60% of something, the opposite operation would be to divide 13.5 by 60% (or 0.6). You can check this by finding 60% of 22.5:

13.5 / 0.6 = 22.5

22.5 x 0.6 = 13.5

Answer:

In the problem, 60% of 22.5 is 13.5.

Step-by-step explanation:

The first thing we have to do is know what the problem is asking us to find. In the problem, we are asked to find the number that 13.5 is 60% of. In order to find this number, we have to divide. We are going to divide 13.5 by 60%. 60% can be turned into decimal form which is 0.6.

13.5 ÷ 0.6 = 22.5

So, the number that 13.5 is 60% of is 22.5.

Answer:

Standard deviation  for the number of people with the genetic mutation = 4.178

Step-by-step explanation:

Explanation:-

Given random sample size 'n' =600

proportion of the Population 'p'=3% or  0.03

Let 'X' be the random variable in binomial distribution

Mean of the  binomial distribution

                              μ = n p

                                 = 600 X 0.03

                                = 18

Mean of the  binomial distribution ' μ ' =18

Standard deviation of the binomial distribution

                                σ = [tex]\sqrt{npq} = \sqrt{600 X 0.03 X 0.97} = \sqrt{17.46} = 4.178[/tex]
