Answer:

LA = 111.375 cm²

SA = 167.375 cm²

*I am not that sure answers are correct

Step-by-step explanation:

Lateral Surface Area-

8.25*9 = 74.25

74.25/2 = 37.125

37.125*3 = 111.375

Surface Area-

8*14 = 112

112/2 = 56

56+111.375 =

167.375

What is 246000000 in standed form need to know whit in 15 min

11Alexandr11 [23.1K]

Answer:

2.46×10^8

Step-by-step explanation:

The decimal point is here

246000000.

Then it must be moved up to here

2.46000000

Those are eight steps from where it was, so to compensate and make sure the number remains the same remove the zeros and multiply by 10^8

Then you have

2.46×10^8

What is the area of the shaded portion of the circle? (16π – 32) in2 (16π – 8) in2 (64π – 32) in2 (64π – 8) in2

GrogVix [38]

Answer:

(16π - 32) in²

Step-by-step explanation:

In the picture attached, the circle is shown.

Area of one-quarter of circle = 1/4*Area of a circle = 1/4*π*radius² = 1/4*π*8² = 16π in²

Area of the triangle = 1/2*base*height = 1/2*8*8 = 32 in²

Shaded area = Area of one-quarter of circle - Area of the triangle = (16π - 32) in²

Your realized income is $2,943.20 /month. How much are your fixed expenses each month? How much could you save per month if you

valkas [14]

Answer:

The saving amount per month is $ 735.8 And

The Expenses amount per month is $2,207.4

Step-by-step explanation:

Given as :

The total per month income = $2,943.20

The saving percentage amount per month = 25% of discretionary money

So , The saving amount per month = 25 % of $2,943.20

= .25 × $2,943.20 = $735.8

The amount which is fixed as each month expenses = total monthly income - total monthly saving

So, Expenses amount per month = $2,943.20 - $735.8

= $2,207.4

Hence The saving amount per month is $ 735.8 And The Expenses amount per month is $2,207.4 Answer

Express in terms of logarithm without exponents

sdas [7]

$\bf log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)
\\ \quad \\
% Logarithm of rationals
\\ \quad \\
% Logarithm of exponentials
log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)\\\\
-----------------------------\\\\
log_b(xy^2z^{-6}\implies log_b(x)+log_b(y^2)+log_b(z^{-6})
\\\\\\log_b(x)+2log_b(y)-6log_b(z)$

now, the one below that, which is equivalent to that? well, just look above it

Have you ever been on or seen a ride like this at a fair or amusement park? Imagine being strapped into your seat at the bottom

The linear relationship is y = 20x, 0 ≤ x ≤ 17.5 and the quadratic relationship is y = -16x² + 288, 0 ≤ x ≤ 3√2

<h3>The equations that represent the relationships</h3>

<u>The linear relationship</u>

When making the trip up, we have:

Rate = 20 feet per seconds

This means that the relationship is:

Distance = Rate * Time

So, we have:

y = 20x

The height of the tower is 350.

So, we have:

20x = 350

Divide by 20

x = 17.5

Hence, the linear relationship is y = 20x, 0 ≤ x ≤ 17.5

<u>The quadratic relationship</u>

The quadratic equation can be represented as:

y = -0.5ax² + vx + h

Where:

a = acceleration due to gravity = 32
v = velocity = 0
h = height = 288

So, we have:

y = -0.5 * 32x² + 0 * x + 288

Evaluate

y = -16x² + 288

When you get to the ground level, we have:

-16x² + 288 = 0

Subtract 288 from both sides

-16x² = -288

Divide by -16

x² = 18

Take the square root of both sides

x = ±3√2

Remove negative domain

x = 3√2

Hence, the quadratic relationship is y = -16x² + 288, 0 ≤ x ≤ 3√2
