PLEASE HELP!! BRAINLIEST AND 10 POINTS !!

Answer:

The interest on the investment is $16,170.93811

Step-by-step explanation:

The rule of the compound interest is [tex]A=P(1+\frac{r}{n})^{nt}[/tex], where

∵ The investment is $45,000

∴ P = 45,000

∵ The interest on the investment is compounded annually at 5.25%

∴ r = 5.25% = 5.25 ÷ 100

∴ r = 0.0525

∴ n = 1 ⇒ compound annually

∵ It is for 6 years

∴ t = 6

→ Substitute them in the rule above

∵ [tex]A=45,000(1+\frac{0.0525}{1})^{1(6)}[/tex]

∴ [tex]A=45,000(1.0525)^{6}[/tex]

∴ A = 61,170.93811

∵ I = A - P, where I is the interest

∴ I = 61,170.93811 - 45,000

∴ I = 16,170.93811

∴ The interest on the investment is $16,170.93811

Answer:

true

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

You start off with 2x + 2x + 2 = 4x + 2.

You would then add like terms, as shown below.

4x + 2 = 4x + 2

Now, you would subtract 4x from both sides, and that would leave you with:

2 = 2

You would now subtract 2 from both sides, which would now leave you with 0.

Answer:

[tex]b.)31\neq -22[/tex]

Step-by-step explanation:

Simplify each equation using PEMDAS:

Parentheses (x)

Exponents x²

Multiplication and Division, left to right × ÷

Addition and Subtraction, left to right - +

It is also important to follow PEMDAS when working within grouping symbols like parentheses.

Also, remember that two negatives make a positive, and when a negative and positive are multiplied, the result is always negative.

Answer:

A full circle has 360 degrees, which means that 100% of the circle is 360 degrees. First convert the percentage into a decimal. If you multiply 360 by 0.90, you get the degree measure that corresponds to the percentage, which is 324.

Step-by-step explanation:

f(x) = 2x^2 + 1

f(-1) means that wherever you see an x on the right hand side, you substitute -1.

f(-1) = 2(-1)^2 + 1 = 2 + 1 = 3

Step-by-step explanation:

Group A = < Group B

Group A has 6 more than total so 1/4t+6

Group B has 3 less than total so t-3

Answer:

m<R = 106°

Step-by-step explanation:

Given,

m<R = (6x+10)°

m<S = (2x+5)°

m<T = (3x-11)°

Now,

6x+10°+2x+5°+3x-11° = 180°{the sum of angles of triangle is 180°}

or, 11x+4° = 180°

or, 11x = 180°-4

or, x = 176°/11

or, x = 16°

therefore, x = 16°

m<R = (6x+10)°

= 6×16°+10°

= 96°+10°

= 106°

Step-by-step explanation:

The height, h in feet, of a rocket is given by, where t is time in seconds.

[tex]h=-16t^2+64t+190[/tex] ...(1)

We need to find the maximum height of the rocket and find the time the rocket was in the air. For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]

[tex]\dfrac{d(-16t^2+64t+190)}{dt}=0\\\\-32t+64=0\\\\t=\dfrac{64}{32}\\\\t=2\ s[/tex]

So, it will reach its maximum height in 2 seconds.

Now put t = 2 in equation (1) as follows :

[tex]h(2)=-16(2)^2+64(2)+190\\\\=254\ \text{feet}[/tex]

So, the maximum height of the rocket and find the time the rocket was in the air is 254 feet and 2 seconds respectively.

Answer:

The maximum height of the rocket is 3600

Step-by-step explanation:

The vertex of the quadratic equation y = ax² + bx + c is (h, k), where

The height of the rocket calculated using the equation y = -16x² + 480x, where y is the height and x is the time

To find the maximum height, do that

Let us do that

∵ y = -16x² + 480x

∴ a = -16 ⇒ the vertex is a maximum point

∴ b = 480

→ Use the rule above to find h

∵ h = [tex]\frac{-b}{2a}[/tex]

∴ h = [tex]\frac{-480}{2(-16)}[/tex] = [tex]\frac{-480}{-32}[/tex]

∴ h = 15

∵ k = y at x = h

→ Substitute x by 15 in the equatuion and y by k to find x

∵ k = -16(15)² + 480(15)

∴ k = -3600 + 7200

∴ k = 3600

∵ The maximum height equal the value of k

∴ The maximum height of the rocket is 3600

Answer:

Options (A), (B), (C) and (E).

Step-by-step explanation:

Option (A).

Slope of AC is equal to the slope of BC.

Since, points A, B and C are collinear points,

Slopes of AC and BC will be equal.

True.

Option (B).

Since, points A, B, C and D are collinear points, slope of AC and BD will be equal.

True.

Option (C).

Points A and C are lying on line 't'.

Therefore, slope of line 't' and line AC will be equal.

True.

Option (D).

Slope of 't' = slope of line AC

                  = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                  = [tex]\frac{AE}{EC}[/tex]

False.

Option (E).

Slope of line 't' = slope of line BD

                         = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                         = [tex]\frac{FB}{FD}[/tex]

True.

Option (F).

Answer:

Angle STR = 78°

Step-by-step explanation:

So, since line QS is a straight line, we know that it's 180°. We also know that angles QTR and STR both add up to 180°. That gives us an equation:

20x + 12 + 10x + 33 = 180

Combine like terms

30x + 45 = 180

Subtract 45 from both sides

30x = 135

Divide both sides by 30

x = 4.5

Now we know the value of x. We just need to plug it into angle STR's given value:

10(4.5) + 33 = angle STR

45 + 33 = angle STR

78° = angle STR
