I NEED TO REPLACE MY CONCRETE IN 7 YEARS. THE TOTAL COST IS $15,000, HOW MUCH DO I NEED TO SAVE ANNUALLY AT 5%.
9514 1404 393
Answer:
$1,754.57
Step-by-step explanation:
If you put the amount in savings at the beginning of the year, then the balance after 7 years is ...
A = P(1 +r)((1 +r)^7 -1)/r . . . . for payment P at annual rate r for 7 years
15000 = P(1.05)(1.05^7 -1)/0.05 = 8.54911P
Then the amount P that needs to be saved is ...
15000/8.54911 = P = 1754.57
You need to deposit $1,754.57 at the beginning of each year for 7 years to have a balance of $15,000 at the end of 7 years.
_____
If you wait until the end of the year to deposit the money, the amount will need to be 5% higher: $1,842.30.
can you guys help me with this equation plzzzzzz
Answer:
b = 1/3
Step-by-step explanation:
Here, we want to solve for the value of b
From the question, we have that;
4^(3b-3) = 1/16
4^(3b-3) = 16^-1
4^(3b-3) = 4^2(-1)
4^(3b-3) = 4^-2
Since base are equal, equate the powers
3b - 3 = -2
3b = -2 + 3
3b = 1
b = 1/3

4 times (12-8) + 2^3. (2 to the 3rd power)
Answer:
It's 48. Heres why:
Step-by-step explanation:
Our equation, I believe, is 4[(12-8) + 2³]. We can do the operations in the parenthesis:
4[(4)+8] (12-8 = 4, and 2³ is 8). If we add 4 + 8, we get 12. Multiply 12 by 4, we get 48.
The program director at a botanical garden surveyed 75 of their annual members about the number of times they visit the gardens every month. The table shows the results of the survey. There are a total of 516 annual members. What is the best estimate for the number of annual members that will visit the botanical garden more than 3 times in the next month?
A) 24 annual members
B) 96 annual members
C) 165 annual members
D) 234 annual members
Answer: C) 165 annual members
Step-by-step explanation:
Those who will visit the garden more than 3 times in the next month will be those who visit 4, 5, and 6 or more times.
Out of the 75 surveyed, the total number of those are:
= 9 + 12 + 3
= 24
That would give a percentage of:
= 24 / 75
= 32%
This means that the best estimate for those who will visit more than 3 times is 32%.
Out of the total number of 516, that is:
= 32% * 516
= 165 members

An Isoceles Triangle has base 6cm long and the opposite angle to the base is 50 degrees l. What is the size of the other angle?
Answer:
65°
Step-by-step explanation:
From the question,
The base angle of an isoceles triangle are equal.
Let the value of the base angles = x°
Sum of angle in a triangle = 180°
⇒ x°+x°+50° = 180°
⇒ 2x°+50° = 180°
⇒ 2x° = 180°-50°
⇒ 2x° = 130°
⇒ 2x°/2 = 130/2
⇒ x° = 65°.
Hence, the size of the other angles is 65°

Please help me with this homework using the substitution method
Answer:
(5, -2)
Step-by-step explanation:
Let's solve the first equation for x: If x + y = 3, and if we subtract y from both sides, we get x = 3 - y. Next, substitute 3 - y for x in the second equation:
3(3 - y) + 2y = 11, or
9 - 3y + 2y = 11
Combining like terms: -3y + 2y = 11 - 9, or
-y = 2, or y = -2.
Then, from the equation x = 3 - y, which we found earlier,
x = 3 - (-2) = 5
Then the solution is (5, -2)

If the terminal point of ø is (-1,0), what is tan ø?
The SOH CAO TOA identity is used to determine the acute angles of a right triangles. The terminal point of ø is (-1,0), what is tan ø is 0
Given the terminal point (-1, 0), the value of tanø is expressed as:
tanø = opposite/adjacent
tanø = y/x
From the coordinate given:
x = -1
y = 0

RP QUESTION!!Faelyn grouped the terms and factored the GCF out of the groups of the polynomial 6x4 – 8x2 + 3x2 + 4. Her work is shown.
Step 1: (6x4 – 8x2) + (3x2 + 4)
Step 2: 2x2(3x2 – 4) + 1(3x2 + 4)
Faelyn noticed that she does not have a common factor. Which accurately describes what Faelyn should do next?
Answer:Faelyn should realize that her work shows that the polynomial is prime.
Explanation:
The only difference between her factors in Step 2 is that the 4 in the first group is negative, while the 4 in the second group is positive.
Rearranging the polynomial to factor it will not change the end result.
Factoring out a negative will make not only one, but both terms, in one of the binomials the opposite sign; this will not make the factors the same.
Factoring only 2x out of the first group will result in having (3x³+4x); this is not the same either.
She should realize that when this happens, her polynomial is prime.

The correct way of factoring 6x⁴ - 8x² + 3x² + 4 is (6x⁴ - 8x²) + (3x² + 4).
What are GCF and distributive property?The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.
We also know that distributive property states a(b + c) = ab + ac.
Given, Faelyn grouped the terms and factored the GCF of
6x⁴ - 8x² + 3x² + 4.
Next step she did is,
(6x⁴ - 8x²) + (3x² + 4).
She should have combined the terms like,'
= (6x⁴ + 3x²) + (- 8x² + 4).
As 6, 3 and 8, 4 has GCF together.
= 3x²(2x² + 1) - 4(2x² - 1).
