Answer:

B) 1.0583^t

Step-by-step explanation:

The formula for the interest earned on an investment is

I = (1 + r)^t

Data:

I = 1.12

t = 2

Calculations:

1.12 = (1 + r)²

Take the square root of each side

1.058 30 = 1 + r

Then, the formula for the interest calculated on a six-month basis is

I = 1.0583^t

The option with the closest answer is B) 1.0582^t.

The question is where did they go wrong with the equation: 2(s-5)=2(s+5)
riadik2000 [5.3K]
For 2(s-5) = 2(s+5), it’s supposed to be:
2s-10 = 2s+10 (this is where it went wrong)
2s-20 = 2s
20 = 4s
5 = s

Below is a savings plan for Adrienne. Use this table to answer the questions below.
jeka57 [31]

Answer:

$196 for twenty-four months. $130 for twelve months  

$80 for one month. $100 dollars for five months.

Step-by-step explanation:

y=mx+b solved is y=5x+75

note- X is the amount of months

y=5(24)+75       y=5(11)+75      y=5(1)+75         y=5(5)+75

y=120+75          Y=55+75        y=5+75            y=25+75

y=195                 y=130             y= 80               y=190

What is the exact perimeter of kite ? Show your work.
Afina-wow [57]

Answer:

<u>The perimeter of the kite is 29 units.</u>

Step-by-step explanation:

1. Let's use the Pythagorean Theorem to find the perimeter of the kite:

With the information given, we have four right triangles with a new point A, intersecting UW and VX. Those triangles are:

Δ UVA

Δ VWA

Δ UXA

Δ XWA

As we can see in the figure, length of UV and VW is the same and the length of UX and WX is also the same.

2. Let's find the value of UV and VW

UV is the hypotenuse of Δ UVA and it sides are 3 and 4 units length. So, we can calculate the length of UV this way:

Length of UV ² = UA ² + VA ²

Replacing with the real values:

Length of UV ² = 3 ² + 4 ²

Length of UV ² = 9 + 16

Length of UV ² = 25

√Length of UV ² = √25

<u>Length of UV  = 5 units ⇒ Length of VW = 5 units</u>

3. Let's find the value of UX and WX

UX is the hypotenuse of Δ UXA and it sides are 3 and 9 units length. So, we can calculate the length of UX this way:

Length of UX ² = UA ² + XA ²

Replacing with the real values:

Length of UX ² = 3 ² + 9 ²

Length of UX ² = 9 + 81

Length of UV ² = 90

√Length of UV ² = √90

<u>Length of UV  = 9.5 units (rounding to the nearest tenth) ⇒ Length of WX= 9.5 units</u>

<u>4. </u>Let's calculate the perimeter of the kite:

Perimeter of the kite = UV + VW + WX + UX

Perimeter of the kite = 5 + 5 + 9.5 + 9.5

<u>Perimeter of the kite = 29 units</u>
