Answer:
f(5)=26
Step-by-step explanation:
hello :
f(n)=f(n-1)+4 means : f(n)-f(n-1)=4 (comon diference for arithm - sequence)
so : f(n) =f(1)+(n-1)×4
f(n) =10+(n-1)×4
f(n) = 4n+6
f(5) = 4(5)+6 =26
How much money will
be spent in interest
alone over the course of
the 4% 30-year
mortgage described in
the table?
Answer:
the answer is 4,800 dollars
Step-by-step explanation:
Interest is amount added for time. In this case, every dollar borrowed will require 1.04 back. This may not seem like much, but it leads to a lot. Multiplying 120,000 by .04, which is 4 % in decimal form, will give you 4,800 dollars.

What is the solution to the equation t minus 15 = 76?
t minus 15 = 76. t minus 15 minus 15 = 76 + 15. t = 91.
t minus 15 = 76. t minus 15 + 15 = 76 + 15. t = 91.
t minus 15 = 76. t minus 15 minus 15 = 76 minus 15. t = 61.
t minus 15 = 76. t minus 15 + 15 = 76 minus 15. t = 61.

xº
50°
What is the value of x?
Answer:
65
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
one of the angle is given as 50 degrees so:
50 + x + x = 180
50 + 2x = 180 subtract 50 from both sides
2x = 130 divide both sides by 2
x = 65
How many pairs of corresponging angles are formed when a transeversal is cut by 2 parallel lines?
Answer: 4
Step-by-step explanation:
There are 4 pairs of corresponding angles are formed when a transversal is cut by 2 parallel lines,
What are parallel lines?Parallel lines are the lines that do not intersect or meet each other at any point in a plane.
They are always parallel and are at equidistant from each other. Parallel lines are non-intersecting lines.
If two parallel lines are intersected by a transversal, then corresponding angles are congruent.
The angles are called corresponding angles. If two parallel lines are cut by a transversal, the corresponding angles are congruent.
When a line is cut by a transversal, 4 angles are formed,
2 angles are >=90° while 2 are <=90°
So when we take 2 parallel lines, 4 pairs are formed.
Hence, there are 4 pairs of corresponding angles are formed when a transversal is cut by 2 parallel lines,

Step-by-step explanation:
Hei has $1,400 in a retirement account earning 4% interest compounded annually. Each year after the first, she makes additional deposits of $1,400. After 5 years, what was her account balance if she did not make any withdrawals? Round each year's interest to the nearest cent if necessary. HELP ASAP
Answer:
$7886.16
Step-by-step explanation:
If the balance increases by 4%, it will be 104% of the original amount. 104% as a decimal is 1.04. Therefore, to calculate the balance with annual compound interest applied, multiply the balance of the account by 1.04 each year.
As Hei makes additional deposits of $1,400 for each year after the 1st year, add $1,400 to the account balance from year 2 onwards before adding the interest.
Let A = account balance
After 1 year
A = 1400 × 1.04 = $1456
After 2 years
A = (1456 + 1400) × 1.04 = $2970.24
After 3 years
A = (2970.24 + 1400) × 1.04 = $4545.05
After 4 years
A = (4545.05 + 1400) × 1.04 = $6182.85
After 5 years
A = (6182.85 + 1400) × 1.04 = $7886.16
Therefore, after 5 years her account balance will be $7886.16

Answer:
A triangle's exterior angle is the angle established by one of the triangle's sides and the extension of one of the triangle's adjacent sides.
Step-by-step explanation:
FACTS:
Each vertex of a triangle has two exterior angles.
It's worth noting that the "outside" angles that are "vertical" to the angles inside the triangle aren't called to as triangle exterior angles.
1. The given triangle's angles are 1, 5, and 6.
2. Angle 3 is perpendicular to angle 5 on the inside.
3. The triangle's outside angles are 2 and 4.
The correct answers are A and B.
A triangle's exterior angle is the angle created by one of the triangle's sides and the extension of one of the triangle's adjacent sides.

24.4 mL
By converting mm to cm, we get

radius (r) = 1.8 cm
To find the volume,
Volume of sphere = 4/3πr3
= 4/3π(1.8)3
Volume = 24.4 cm3
To find the capacity,
1 cm3 = 1 mL
Capacity = 24.4 mL

7. At what rate was an investment made that obtains $359.80 in interest compounded annually on $668 over five years?
[compound interest rate]
Answer:
Rate = 13.173% per year
Step-by-step explanation:
**Not 100% sure about this answer, but I think it's right.**
Calculation Steps:
Solving for rate r as a decimal
r = n[(A/P)^1/^nt - 1]
r = 1 × [(668.00/359.80)^1/^(1)^(5) - 1]
r = 0.131731
Then convert r to R as a percentage
R = r * 100
R = 0.131731 * 100
R = 13.173%/year

Kevin has a deck of cards. There are 10diamonds, 5 spades, 12 clubs and 3 hearts.A card was chosen at random. What is the
probability of not choosing a diamond card?
Answer: 2/3.
Step-by-step explanation: When you add all the spades, hearts, clubs, and diamonds cards together, you get 30 in total. 1/3 of the 30 cards in total are diamonds, so the other 2/3 can be drawn as well. The probability of not choosing a diamond card is 2/3, since the remaining 1/3 is all diamonds.

What is the length of the line segment whose endpoints are A(-1,9) and B(7,4) in the simplest radical form?
length : [tex]\sf \sqrt{89}[/tex]
Explanation:
use the distance formula : [tex]\sf \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
using the formula:[tex]\sf \rightarrow \sf \sf \sqrt{(7--1)^2+(4-9)^2}[/tex]
[tex]\sf \rightarrow \sf \sf \sqrt{(8)^2+(-5)^2}[/tex]
[tex]\sf \rightarrow \sf \sf \sqrt{64+25}[/tex]
[tex]\sf \rightarrow \sf \sf \sqrt{89}[/tex]
Answer:
[tex]\sf \sqrt{89}[/tex]
Step-by-step explanation:
Let A = [tex]\sf (x_1,y_1)[/tex] = (-1, 9)
Let B = [tex]\sf (x_2,y_2)[/tex] = (7, 4)
Distance formula:
[tex]\sf d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Input values into the distance formula and solve for d:
[tex]\sf \implies d=\sqrt{(7-(-1))^2+(4-9)^2}[/tex]
[tex]\sf \implies d=\sqrt{8^2+(-5)^2}[/tex]
[tex]\sf \implies d=\sqrt{64+25}[/tex]
[tex]\sf \implies d=\sqrt{89}[/tex]

Which statement is correct for the graph of the specified function?
A) The rate of change for the linear function is 2.
B) The rate of change for the linear function is −1.
C) The maximum value of the quadratic function occurs at y = 4.
D) The minimum value of the quadratic function occurs at x = 4.
The correct statement regarding the function plotted in the graph is:
C) The maximum value of the quadratic function occurs at y = 4.
What is the rate of change of the linear function?When x = 0, y = -7, and when x = -5, y = 8, hence the rate of change(change in y divided by change in x) is given by:
R = [8 - (-7)]/-5 - 0 = 15/-5 = -3
What is the maximum value of the quadratic function?It is concave down, hence it has only a maximum value at y = 4 and not a minimum value, hence option C is correct.

-2(11-12)=-4(1-6x)
Answer:
Step-by-step explanation:
-2(11-12)=-4(1-6x) becomes -2(-1) = -4(1 - 6x)
Next, we divide both sides by -2, obtaining -1 = 2(1 - 6x), and then
-1 = 2 -12x, or
-3 = -12x
Simplifying this result, we get 1 = 4x, or x = 1/4
We conclude that -2(11-12)=-4(1-6x) has ONE solution, which is x = 1/4
