Mathematics

Alchen [17]3 years ago
8 0

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange - 3x + 4y = 5 into this form

Add 3x to both sides

4y = 3x + 5 ( divide all terms by 4 )

y = \frac{3}{4} x + \frac{5}{4} ← in slope- intercept form

with slope m = \frac{3}{4}

• Parallel lines have equal slopes, thus

y = \frac{3}{4} x + c ← is the partial equation of the parallel line

To find c substitute (2. 1) into the partial equation

1 = \frac{3}{2} + c ⇒ c = - \frac{1}{2}

y = \frac{3}{4} x - \frac{1}{2} ← equation of parallel line

A cube has a volume of 64. What is the length of one side of the cube?
bearhunter [10]

Answer:

4

Step-by-step explanation:

The volume of a cube can be represented as s^3 = v, where s = side and v = volume. In this case, we're given the volume as 64, so s^3 = 64. To solve this problem, we first have to know what a cube root is.

What's a cube root?

  • The cube root of a number is the number you multiply by itself 3 times to get another number.
  • One common cube is 27, and the cube root of it is 3 because 3 x 3 x 3 = 27.

Given the information above, let's go in order with the list of cube roots to see which one has a cube of 64.

  • 1: 1 x 1 x 1 = 1.
  • 2: 2 x 2 x 2 = 8.
  • 3: 3 x 3 x 3 = 27.
  • 4: 4 x 4 x 4 = 64. (This is the cube root!)

We found the cube root of 64, or the side of the cube with a volume of 64. The side of the cube, therefore, is 4.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Someone please help me will give BRAILIEST!!!!

Answer: Choice A) $4500.33

---------------------------------------------------------------------

Explanation:

The formula you'll use is
F = P*(1+r)^t

where
F = final amount
P = initial amount
r = growth rate (in decimal form)
t = time in years

In this case,
F = unknown (this is what we're trying to figure out)
P = 3046 
r = 0.05 (since 5% = 5/100 = 0.05)
t = 8

Plug those three known values into the formula and evaluate

F = P*(1+r)^t
F = 3046*(1+0.05)^8
F = 3046*(1.05)^8
F = 3046*1.4774554
F = 4500.3291484
F = 4500.33 ... round to the nearest penny
