Jacob is unsure how long it will take to save $50,000. He knows that he'll make an initial investment of $5,000, and he can earn

maksim [4K]

Answer:

It will take Jacob 36 years to reach his goal

Step-by-step explanation:

In this question, Jacob is intending to save $50,000 but he is doing this by saving $5,000 at an interest which is compounded two times a year (semi-annually). We are tasked with calculating the number of years it will take him.

Mathematically, to solve this, what we use is the compound interest formula.

This is;

A = P(1 + r/n)^nt

Where in the question A is our savings target of $50,000

P is our initial amount saved of $5,000

r is the rate at 6.5%

n is the number of times interest will be compounded per year= 2

and t is the number of years it will take.

We plug all these values respectively to yield;

50,000 = 5,000(1 + 0.065/2)^(2t)

Divide through by 5,000

we have;

10 = (1.0325)^2t

Take the logarithm of both sides

Log 10 = Log (1.0325)^2t

Log 10 = 2tLog (1.0325)

2t = Log10/Log1.0325

2t = 72

t = 72/2

t = 36 years

Find the coordinates of the midpoint M of the segment with the given endpoints. Then find the distance between the two points. R

MrRa [10]

Question 1. Midpoint

Answer: M(-2,4)

Explanation:

1) The coordinates of the midpoint, M (x,y) between two points (x₁,y₁) and (x₂, y₂) are:

x = (x₁ + x₂) / 2 and y = (y₁ + y₂) / 2

2) Replacing the coordinates of the given points P (-4, 1) and Q (0,7) you get:

x = (- 4 + 0) / 2 = - 2, and
y = (1 + 7) / 2 = 4

So, the answer is M (-2,4)

Question 2: The distance between the two midpoints is:

Answer: 7.21

Explanation:

1) Use the formula of distance, which is an application of Pythagora's theorem:

d² = (x₂ - x₁)² + (y₂ - y₁)²

2) Substitute values:

d² = (0 - (-4))² + (7 - 1)² = 4² + 6² = 16 + 36 = 52 ⇒ d = √52 ≈ 7.21

Solve the system of equations using elimination/combinations-2x -y = -4 x + 2y =5

sweet-ann [11.9K]

Answer:

x = 1, y = 2

Step-by-step explanation:

In the elimination method to solve a system of linear equations, one of the two equations is added/subtracted to the other, in order to eliminate one variable from the equation.

In this problem, we have the following two equations:

$-2x-y=-4\\x+2y=5$

To solve the system, first we multiply by 2 both sides of the second equation, and we get:

$2(x+2y)=2(5)\\2x+4y=10$

So now the system is

$-2x-y=-4\\2x+4y=10$

Now we add the two equations, and we get:

$(-2x+2x)+(-y+4y)=(-4+10)\\3y=6$

So, we get

$y=\frac{6}{3}=2$

Now we can substitute this value of y into the eq.(2), and we get:

$x+2y=5\\x+2(2)=5\\x+4=5\\x=5-4=1$

#20, what is this answer ?

Charra [1.4K]

Answer:

b = 2A/h

b = 6 inches

Step-by-step explanation:

$A = \frac{1}{2} bh \\ \\ 2A =bh \\ \\ \purple{b = \frac{2A}{h}} \\ \\ plug \: A = 12 \: and \: h = 4 \\ \\ b = \frac{2 \times \cancel{12}}{ \cancel4} \\ \\ b = 2 \times 3 \\ \\ b \: = 6 \: in$
