The amount invested at each rate

Investment at 7% = $25000

Investment at 2%  = $11,000

<h3>What is investment?</h3>

Investment definition is an asset acquired or invested in to build wealth and save money from the hard earned income or appreciation.

Given:

Larry Mitchell invested = $36,000 at 7% annual simple interest

the rest at 2% annual simple interest.

Total investment = 36000

let the investment at 7% is x

then, invested at 2% = 36000 - x

Total interest earned = $1,970

Simple interest = principal * rate * time

Investment at 4%:

(x * 0.07) + [(36000 - x) * 0.02] = 1970

0.07x + 720 - 0.02x= 1970

0.05x = 1970-720

0.05x = 1250

x= 25000

Hence,

Investment at 7% = $25000

Investment at 2% = $36,000 - $25000 = $11,000

A civil engineer is mapping the overhead clearance of his family’s property on a coordinate grid. The ground is represented by t
statuscvo [17]

The distance from the base of the tree to the tallest would be 14.21 cm

<h3>We have the following data points in this question</h3>

X1 = 8 feet

y1 = 16 feet

x2 = 11 feet

y2 = 9 feet

To proceed with the solution we have to

We have to solve for the shorter tree

\sqrt{(y2 -y1)^2 + (x2-x1)^2} \\\\= \sqrt{9-0^2 + 11-0^2}

<em>= </em>9² + 11²

= √81 +121

= 14.21

<h3>For the taller tree we would have</h3>

√8² + 16²

= √64 +256

= 17.89

Help me please!!! very urgent!
Simora [160]

Step-by-step explanation:

The perpendicular line has a slope that is the negative reciprocal of the other line's slope. So, in this case, the slope should be 1/3 (it's positive because a negative times a negative is a positive). This gets rid of all of the answers except for the last, I suppose.

Please Help I'm having trouble!!!!!!
Alla [95]

Answer:

  • b = P - a - a - B
  • b = P - 2a - B

Step-by-step explanation:

The perimeter is the sum of the lengths of the sides, so is ...

  P = B + a + b + a

Subtracting the terms that are not "b" from both sides of the equation, you get

  P - a - a - B = b

Swapping sides of the equal sign, this matches the first choice:

  b = P - a - a - B

The two "-a" terms are "like terms" so can be added together. The result matches the second choice.

  b = P - 2a - B
