Given thet SU = UT = 6 units, hence 6 + 6 = 12 showing that the expression SU + UT = RT is TRUE. Option A is correct

A line is defined as the distance between two points

Since the point T bisects RT and TU = 6 units, hence the point U bisects TS.

The sum of the segment SU and UT will be RT

Given that SU = UT = 6 units, hence 6 + 6 = 12 showing that the expression SU + UT = RT is TRUE

The value of f(-3) for the function f(a)  = -2a² - 5a + 4 is 1.

Function relates input and outputs. The outputs are called the ranges of dependent variables while the input are called domain or independent variables.

Therefore,

f(a)  = -2a² - 5a + 4

Hence,

f(-3) = -2(-3)² - 5(-3) + 4

Therefore,

f(-3) = -18 + 15 + 4

f(-3) = -3 + 4

f(-3) = 1

Answer: 25

Step-by-step explanation:

we have three sides, let's look at the two smaller sides first.

check the picture below atop

if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side?  Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 9 - 4 = 5.  However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle.  So whatever the third side may be, it must be greater than 5.

check the picture below at the bottom

Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 4 + 9 = 13.  However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle.  So whatever the third side may be, it must be less than 13.

Answer:

20

Step-by-step explanation:

If the order matters, we can use the product rule to show each of the [tex]20[/tex] coins can be chosen in [tex]5[/tex] ways, for a total of [tex]5^{20[/tex] ways, assuming you have enough of each type of coins.

If the order does not matter (which in the case it probably does not) you have to use an r-combination. The formula is[tex]C(n+r-1,r)[/tex]. Here [tex]n=5[/tex] and [tex]r=20[/tex]. So we get [tex]C(24,20)[/tex].

Answer:

174 CM²

Step-by-step explanation:

First we split up the triangular prism into shapes we can better understand (2 triangles, and 2 rectangles)

We solve the area of the triangles by using the formula to the area of a triangle (B·H÷2) 8·6÷2=24

There are 2 triangles therefore we get 2*24 which is 48 CM²

Now we calculate the area of the rectangles (7·10=70, 8·7=56)

Finally we add up all the numbers (70+56+48=174 CM²)

Therefore the surface area of the triangular prism is 174 CM², respectively.

What interest rate do you need to double your money in 10 years?

R = 72/t = 72/10 = 7.2% Example Calculation in Months If you invest a sum of money at 0.5% interest per month, how long will it take you to double your investment? t=72/R = 72/0.5 = 144 months (since R is a monthly rate the answer is in months rather than years)

Therefore, since R is a monthly rate the answer is in months rather than years, the interest rate that you need for an $5000 investment compounded annually to double in 10 years is 7.2%

The expression √(5 - n)² is a rational expression, and the simplified expression of √(5 - n)² is 5 - n

The expression is given as:

√(5 - n)²

Where n < 5

The inequality n < 5 has no effect on the expression.

So, we have:

√(5 - n)² = 5 - n

Hence, the simplified expression of √(5 - n)² is 5 - n

The figure is a trapezoid (or trapezium), and the exact length of the trapezoid is 5 units

The figure is a trapezoid with the following parameters:

Area = 107.95

Base= 12

Height = 12.7

Length = x

The area of a trapezoid is:

Area = 0.5 * (Base + Length) * Height

So, we have:

0.5 * (12 + Length) * 12.7 = 107.95

Evaluate the product

(12 + Length) * 6.35 = 107.95

Divide both sides by 6.35

12 + Length = 17

Subtract 12 from both sides

Length =  5

Hence, the length of the trapezoid is 5 units

If the dimensions of the prism are doubled the surface area of the enlarged prism is 640 cm²

where

h = height

l = length

w = width

Therefore, if the dimension of the prism are doubled the new dimension will be as follows:

l = 5(2) = 10 cm

w = 2(2) = 4 cm

h = 10(2) = 20 cm

Therefore,

surface area = 2(10 × 4) + 2(10 × 20) + 2(20 × 4)

surface area = 2(40) + 2(200) + 2(80)

surface area = 80 + 400 + 160

surface area = 640 cm²

[tex]g(-3) = 3(-3)^{2} -4[/tex]

[tex]g(-3) =3(9)-4[/tex]                      Square -3 to get 9

[tex]g(-3) = 27-4[/tex]                         Multiply 9 by 3 to get 27
