Answer:
it 5.5⋅10−^8m
Step-by-step explanation:
Unless I'm missing something important here, you can find the difference between the two wavelengths by subtracting one from the other. Since you're interested in finding how much longer the wavelength associated with the orange light is, subtract the wavelength of the green light from the wavelength of the orange light. You know that the two measured wavelengths are 6.15 ⋅ 10 − 7 m → orange light 5.6 ⋅ 10 − 7 m → green light Therefore, the difference between the two wavelengths will be Δ wavelength = 6.15 ⋅ 10 − 7 m − 5.6 ⋅ 10 − 7 m = 5.5 ⋅ 10 − 8 m
A countrys population in 1990 was 145 million. In 1998 it was 151 million. Estimate the population in 2015 using the exponential growth formula. Round your answer to the nearest million
Answer:
The population in 2015 will be 165 million.
Step-by-step explanation:
The exponential growth formula is given by:
[tex] f(t) = a(1 + r)^{\Delta t} [/tex]
Where:
a: is the initial population
r: is the rate of increase
Δt: is the time
With the initial information we can find the rate:
[tex] 151 = 145(1 + r)^{1998-1990} [/tex]
Using logarithm:
[tex] ln(151) = ln(145) + 8[ln(1 + r)] [/tex]
[tex] ln(1 + r) = \frac{ln(151) - ln(145)}{8} [/tex]
[tex] ln(1 + r) = 5.0683 \cdot 10^{-3} [/tex]
Using exponential:
[tex] e^{ln(1 + r)} = e^{5.0683 \cdot 10^{-3}} [/tex]
[tex] r = 5.081 \cdot 10^{-3} [/tex]
Now, we can find the estimated population in 2015:
[tex] f(t) = 151(1 + 5.081 \cdot 10^{-3})^{2015-1998} [/tex]
[tex] f(t) = 165 [/tex]
Therefore, the population in 2015 will be 165 million.

A new car that sells for $44,000 depreciates 25% each year. Write a function that models the value of the car. Find the value of the car after 4 years.
can you answer the equation to? please hurry!
Answer:
Value = 44,0000(0.75)^t
Where t = number of years
Value after 4 years = 44,000 (0.75)^4

the volume would be inside of the spear so i could be wrong but you would do 10 multiplied by 21 and you get 210. IF you did base and height the base would be 10ft and the height would be 21ft then you just do base times height and that gets you 210 . i could be wrong though

HELP WITH PLEASE! I’ll give you brilliance
Answer:
a:95
b: a=75
Step-by-step explanation:
For a:
The angles are supplementary meaning they add to 180º. So you can set up an equation: x + 85 = 180
Subtract 85 from both sides:
x = 95º
For b:
Since it's an isosceles triangle (2 congruent sides), the base angles are equal to each other. So a = 75º

Arectangle has a width that is 8 centimeters less than its length. The perimeter of the rectangle is 56 centimeters. Find both the width and length of the rectangle. Show your work.
Answer:
L=18cm
W=10cm
Step-by-step explanation:
Given data
let the length be x
L=x
Width= x-8
W= x-8
Perimeter= 56cm
But we know that the perimeter is expressed as
P=2L+2W
substitute our data
56=2(x)+2(x-8)
56=2x+2x-16
56+16=4x
72=4x
divide both sides by 4
x= 72/4
x=18cm
Hence the Length is 18cm
L=18cm
The width= 18-8
W=10cm
Mr. Garza's family is attending the local soccer game. He has 30 to spend on food and drinks . The cost of chips is $2 and the cost of a drink is $3 . Which of the following inequalities represents all possible combinations of c , and d, the number of drinks , that Mr. Garza can purchase?
Answer:
$6
Step-by-step explanation:
let x and y be the number of chip and pretzel bags respectively : 4x%2B2y%3 C=20 : if x=1 then 4%281%29%2B2y%3C=20--->{{2y<=16}}}--->y%3C=8 : if x=3 then 4%283%29%2B2y%3C=20--->{{2y<=8}}}--->y%3C=4 : so chips 1 and pretzels 8 : chips 3 and pretzels 4.
5 – x = 23 yea wth is this lol
Answer:
x=-18
Step-by-step explanation:
Answer:
x = -18
Step-by-step explanation:
5 - x = 23
5 - 5 - x = 23 - 5
-x = 18
-1x / -1 = 18 / -1
x = -18

Lin says she has memorized the lengths of a few right triangles, for example, 3, 4, and 5. She is trying to compile a list of several right triangles but needs your help. Find the side lengths of at least two other right triangles.
Answer:
6-8-10
9-12-15
5-12-13
Step-by-step explanation:
We know the 3-4-5 right triangles work when you multiply the sides by anything. For example. 6-8-10 and 9-12-15 work.
If you want other right triangles that follow a similar pattern, 5-12-13 is also viable. 10-24-26 & 15-36-39 are all right triangles
The 6, 8, 10, and 9, 12, and 15 are other sides of the right-angle triangle after applying Pythagoras theorem.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
We have:
Lin says she has memorized the lengths of a few right triangles, for example, 3, 4, and 5.
There are 6, 8, 10, 9, 12, and 15 other sides of the right-angle triangle.
On applying Pythagoras theorem.
6² + 8² = 10²
9² + 12² = 15²
Thus, the 6, 8, 10, and 9, 12, and 15 are other sides of the right-angle triangle after applying Pythagoras theorem.

6. SAS (side angle side)
7. CPCTC (coresponding parts of congruent triangles are congruent)
Find the measure of the angle marked “?”
Answer:
137
Step-by-step explanation:
A linear pair adds up to 180 so if you subtract 180 minus 43 its 137 (a)
Then since a parallel line cut by a transversal forms alternate interior angles, (b) would equal 137 also
The since vertical angles are congruent, (b) is equal to ? which is 137
