Answer:
The second term is 12.6
Step-by-step explanation:
Let us solve the question
∵ The recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11
∵ f(1) = 4
→ To find the 2nd term, sunstitute n by 2
∵ n = 2
∴ f(2) = 0.4 · f(2 - 1) + 11
∴ f(2) = 0.4 · f(1) + 11
→ Substitute f(1) by 4
∵ f(2) = 0.4 · 4 + 11
→ Simplify the formula
∴ f(2) = 1.6 + 11
∴ f(2) = 12.6
∴ The second term is 12.6

Explain why it is important to line up decimal points when you are adding and subtracting decimals. Use the problem 6.32 – 0.5 in your explanation
Answer:
Kindly check explanation
Step-by-step explanation:
When performing addition and subtraction of decimals, it is important to arrange the numbers being added or subtracted such that the decimal points are in line. This is particularly important so that the place value of the numbers are in accord.
To simplify, when then decimals are in line, then the tenth value of the first number will be added to the tenth value of the second. Without this arrangement, one might be adding the hundredth placed value to the tenth or unit value which is mathematically incorrect and will yield a wrong result.
For instance :
6.32 - 0.5
Here, when the decimal point of each number is in line, the tenth placed value of the first number (3) matches the tenth placed number of the second number (5) and all others also fall in place automatically.
____6.32
- ___0.5

Hector invests $10,000 at age 21. He hopes the investments will be worth $150,000 when he turns 50. If the interest compounds continuously, approximately what rate of growth will he need to achieve his goal? Write your answer as a percentage rounded to one decimal place.
Answer:
9.33%
Step-by-step explanation:
Step one:
given
Principal= $10,000
Final amount = $150,000
time = 50-21= 29 years
Required
The rate
Step two:
to solve for the rate we can apply the formula for rate as
r = ln(A/P) /t
r= ln(150000/10000)/29
r= ln(15)/29
r=2.7080502011/29
r=0.0933
r= 0.0933*100
r= 9.33%

Can anyone please help I am struggling with math and Noone wants to help me and I want to learn so does anyone understand HOW u factor this
Answer:
Step-by-step explanation:
256 = 16×16=4×4×4×4 = 4^4
X^4-4^4 = (x^2)^2 - (4^2)^2
Using algebraic identity a^2-b^2 = (a+b)(a-b)
We get (x^2+4^2)(x^2-4^2)
(x^2+4^2)(x+2)(x-2)

2. A solar lease customer built up an excess of 6,500 kilowatt hours (kwh) during the summer using his solar
panels. When he turned his electric heat on, the excess began to be used up at a rate of 50 kilowatt hours
per day.
(a) If E represents the excess left and d represents (b) How much of the excess will be left after one
the number of days since the heat has been month (use a month length of 30 days)?
turned on, write an equation for E in terms of d.
(c) If the heat will need to be turned on for 5 months, will the excess be enough to last through this time
period? Justify your answer.
9514 1404 393
Answer:
a) E = 6500 -50d
b) 5000 kWh
c) the excess will last only 130 days, not enough for 5 months
Step-by-step explanation:
Given:
starting excess (E): 6500 kWh
usage: 50 kWh/day (d)
Find:
a) E(d)
b) E(30)
c) E(150)
Solution:
a) The exces is linearly decreasing with the number of days, so we have ...
E(d) = 6500 -50d
__
b) After 30 days, the excess remaining is ...
E(30) = 6500 -50(30) = 5000 . . . . kWh after 30 days
__
c) After 150 days, the excess remaining would be ...
E(150) = 6500 -50(150) = 6500 -7500 = -1000 . . . . 150 days is beyond the capacity of the system
The supply is not enough to last for 5 months.

Answer:
1) I just simply added the numerators because the denominators of both fractions are equal. As the denominators are same , I simply wrote 6 by taking the L.C.M of both denominators.
4)
[tex] \frac{5x - 3}{6} + \frac{x - 9}{6} [/tex]
[tex] = > \frac{5x - 3 + x - 9}{6} [/tex]
[tex] = > \frac{6x - 12}{6} [/tex]
Taking 6 common from numerator,
[tex] = > \frac{6(x - 2)}{6} [/tex]
Cancelling 6 from both numerator & denominator,
[tex] = > x - 2[/tex]

How many \frac{1}{3} 3 1 inch cubes does it take to fill a box with width 22 \frac{2}{3} 3 2 inches, length 33 \frac{1}{3} 3 1 inches, and height 22 \frac{1}{3} 3 1 inches?
Answer:
560Step-by-step explanation:
First we need to find the volume of the cube;
Volume = Length * Width * height
Given;
Length = 3 1/3 in
Width = 2 2/3 in
Height = 2 1/3 in
Volume = 3 1/3 * 2 2/3 * 2 1/3
Volume = 10/3 * 8/3 * 7/3
Volume = 560/3 in^3
To know thw amount of 1/3 in^3 it takes to fill the box, we will take the ratio of the volume to the unit volume;
Ratio = 560/3÷1/3
Ratio = 560/3 * 3/1
Ratio = 560
Hence it will take 560 1/3 in^3 to fill a box with that volume

The two shapes are similar. Solve for x. Show all work.
Answer:
X= 24

Answer:
x = 25Step-by-step explanation:
The two shapes are similar
As per similarity, the corresponding sides have same ratio. Knowing the ratio we can find the value of the side x:
10/4 = 15/6 = 30/12 = x/102.5 = x/10x = 2.5*10x = 25the rectangular post shown at the right measures 2w-30 by w. the poster has an area of 5400 cm^2. what is The value of w ?
Step-by-step explanation:
w(2w - 30) = 5400
2w²- 30w = 5400
2w² - 30w - 5400 = 0
(w - 60 ) ( w + 45 ) = 0
w= 60 w= - 45
only take the positive value
therefore w = 60
Which step in the construction of copying a line segment ensures that the new line segment has
the same length as the original line segment?
Answer:
Here are the steps I think you probably will go through.
1. Draw a line that is longer than the segment but shorter than the width of the page.
1a. Make sure this line is at least 1/2 inch from the left hand side.
2. Use a compass to measure the length of the original segment. Never use a ruler. Rulers do not exist in pure geometry.
3. Measure out the distance on the line you just drew with the compass. One end is on the left hand edge and the other end (the pencil end) is marking the segment so it is the same length as the compass. You are done.
The key step either two or three.
Answer: Step Two
Draw a line that is longer than the segment but not wider than the page's width. This line should be at least 1/2 inch away from the left-hand side. After that, measure the length of the original segment with a compass. Following that step, measure the distance along the compass line. (One end is on the left edge, while the other (the pencil end) is used to mark the section so that it is the same length as the compass) Step two is the most important step in the process of copying a line segment to ensure that the new line segment is the same length as the original.

If x and (x+50°) are complementary angles. find the angles
Step-by-step explanation:
When the sum of two angles is equal to 90 degrees, they are called complementary angles.
So
x + x + 50° = 90°
2x = 90° - 50°
2x = 40°
x = 40°/2
x = 20°
x + 50 = 20 + 50 = 70°
Hope it helps :)
Answer:
let 1st angle be x
and another angle be x+50°
two angles are said to be complementary,if the some of their measures is 90°
so,
x+x+50=90
2x+50 =90
2x=90-50
x=40/2
:-x= 20 ....... 1st angle
another angle (x+50)=20+50=70°

Answer:
C.) 4 sqrt2
Step-by-step explanation:
ON=MN
therefore you can use pythagereum theorum here in a right triangle
as the hypotnuese is 8 you know that ON and MN is equal to the sqrt of 32 each. As A^2+ B^2=C^2
C=8 so C^2= 64 therefore,
A^2+ B^2=64 therefore,
A^2= 32 and B^2=32
you take the sqrt of 32 you get 4sqrt2
