Which is the graph of f (x) = 4 (one-half)^x?
On a coordinate plane, an exponential decay function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It crosses the y-axis at (0, 4) and goes through (1, 1).

Answer:

Jimmy is correct!

Step-by-step explanation:

The last answer is correct, hope this helps!

Answer:

The correct answer is E, 551.6 square feet.

Step-by-step explanation:

I think we can assume that the two ends are perfect semi-circles, although that's not clearly specified.

In that case, the total area we have is that of a 15x25 foot rectangle, plus a circle with a diameter of 15ft.

So lets work that out.  The rectangle is easy, as the area is just width times height. 15 ft * 25 ft is 375 ft²

The area of a circle is defined as πr².  We're given the diameter, which is twice the radius, so the collective area of the two ends would be π × 7.5² which equals π × 56.25, or approximately 176.7 square feet.

Now we just need to add those together:

375 + 176.7 = 551.7

The difference in answer will be due to rounding, so we know that the correct answer is E, despite their answer being rounded incorrectly.

Answer:

Domain: (-5, 1)

Range: (-1, 5)

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, the line's x-values span from -5 to 1. Since both are open dot, they are exclusive from the domain:

Interval Notation: (-5, 1)

Inequality Notation: -5 < x < 1

According to the graph, the line's y-values span from -1 to 5. Since both are open dot, they are exclusive from the range:

Interval Notation: (-1, 5)

Inequality Notation: -1 < y < 5

Answer:

She is not because Paul deposited more money than her, which was enough so that he would earn more interest.

Step-by-step explanation:

Monica

i = prt

i = 200 * 0.033 * 12

(12 is represented as months)

Multiply.

i = 79.2

Paul

i = prt

i = 300 *  0.024 * 12

(you can choose months or years, but they have to be the same)

Multiply.

i = 86.4

Answer

Monica is wrong because Paul deposited more money than her, which was enough so that he would earn more interest.

Answer:

C) 20.67 meters per second

Step-by-step explanation:

62÷3 = 20.67

Answer:

-20

Step-by-step explanation:

5 - 25 is negative 20 and since V does not have a number attached to it you do not divide it by anything

Move the constant to the right side and change the sign

[tex]v < 5 - 25[/tex]

Subtract 25 from 5

[tex]v < - 20[/tex]

Answer:

(a) [tex]5 * (2x - 1) = 10x - 5[/tex]

(b) [tex]6 * x = x + 2x + 3x[/tex]

(c) [tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - 3[/tex]

(d) [tex]y(3x + 4z) = 3xy + 4yz[/tex]

(e) [tex]z(2xy - 3y + 4x) = 2xyz - 3yz + 4xz[/tex]

Step-by-step explanation:

Solving (a):

Given

[tex]10x - 5[/tex]

Required

Express as a product

Express 10x as 5 * 2x

[tex]10x - 5 = 5 * 2x - 5[/tex]

Apply distributive property

[tex]10x - 5 = 5(2x - 1)[/tex]

[tex]10x - 5 = 5 * (2x - 1)[/tex]

So:

[tex]5 * (2x - 1) = 10x - 5[/tex]

Solving (b):

Given

[tex]x + 2x + 3x[/tex]

Required

Express as a product

Express 2x and 3x as 2 * x and 3 * x, respectively

[tex]x + 2x + 3x = x + 2*x + 3*x[/tex]

Apply distributive property

[tex]x + 2x + 3x = x(1 + 2 + 3)[/tex]

[tex]x + 2x + 3x = x(6)[/tex]

[tex]x + 2x + 3x = 6*x[/tex]

So:

[tex]6 * x = x + 2x + 3x[/tex]

Solving (c):

Given

[tex]\frac{1}{2}(x - 6)[/tex]

Required

Express as a sum/difference

Apply distributive property

[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - \frac{1}{2}*6[/tex]

[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - \frac{6}{2}[/tex]

[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - 3[/tex]

Solving (d):

Given

[tex]y(3x + 4z)[/tex]

Required

Express as a sum/difference

Apply distributive property

[tex]y(3x + 4z) = 3x * y + 4z * y[/tex]

[tex]y(3x + 4z) = 3xy + 4yz[/tex]

Solving (e):

Given

[tex]2xyz - 3yz + 4xz[/tex]

Required

Express as a product

Factorize

[tex]2xyz - 3yz + 4xz = 2xy * z - 3y * z + 4x * z[/tex]

Apply distributive property

[tex]2xyz - 3yz + 4xz = z(2xy - 3y + 4x)[/tex]

So:

[tex]z(2xy - 3y + 4x) = 2xyz - 3yz + 4xz[/tex]

Answer:

The answer is 1,440 (sorry if it's wrong)

so you multiply 4,000 by 1.8% which u will get 72 then multiply 72 by 20 and then that will get you 1,440 again sorry if it's wrong

Answer:

D

Step-by-step explanation:

Following Pythagorean Theorom, we know a^2 + b^2 = c^2. We know b and c.  a^2 + 5^2 = 13^2.

a^2 + 25 = 169

a^2 = 144

a = √144

a = 12

So, the answer is 12, which means we pick D

Step-by-step explanation:

Answer:

4% of people had a mild allergic reaction

Step-by-step explanation:

16 is 4% of 400

[tex]y = p\% \times x[/tex]

[tex]p\% = y \div x[/tex]

[tex]p\% = 16 \div 400[/tex]

[tex]p = 0.04[/tex]

Convert decimal to percentage

[tex]p\% = 0.04 \times 100 = 4\%[/tex]

My Answer:

I am pretty sure it would be around 4%

Answer:7 rides

Step-by-step explanation:

First subtract 21.50-4=17.50

Then divide 17.50 ÷2.50=7

Answer:

When writing a fraction there are two main parts: the numerator and the denominator. The numerator is how many parts you have. The denominator is how many parts the whole was divided into. Fractions are written with the numerator over the denominator and a line in between them.

So technically, Yes. How ever, I would need more information to give you an example.
