The sum of the first 75 terms of the sequence is -5.068*10^34
Given the following geometric sequence
[tex]a_1 = \frac{-1}{3} \\a_i = a_{i-1}*(-3)[/tex]
The sum of the nth term of the GP is expressed as;
[tex]S_n = \frac{a(1-r^n)}{1-r}[/tex]
a = -1/3
n = 75
r = a₂/a₁
a₂ = -3a₁
a₂ = -3(-1/3)
a2 = 1
r = 1/(-1/3)
r = -3
Substitute the given values in the formula;
[tex]S_n = \frac{-1/3(1-3^{75})}{1-(-3)}\\S_{75} = \frac{-1/3(3^{75}-1)}{1+3} \\S_{75} = \frac{-1/3(6.082 \times 10^{35}-1)}{4}\\S_{75} = \frac{-1/3(6.082 \times 10^{35})}{4}\\S_{75} = -0.5068 \times 10^{35}\\S_{75} = -5.068 \times 10^{34}\\[/tex]

Let's verify is the corresponding sides have same ratio:
ΔABC, sides: 6, 9, 11ΔXYZ, sides: 21, 31.5, 38.5Ratios:
6/21 = 2/7 (divide by 3)9/31.5 = 2/ 7 (divide by 4.5)11/38.5 = 2/7 (divide by 5.5)The ratios are same, so the triangles are similar

Based on the scatterplot and computer output, a
reasonable estimate for the stock price for week 95 is:
A popular social media platform has begun offering
stock shares to the public. In the past 2 years, the
price of the stock has generally increased. An
investment specialist gathers data on the stock price
during the past 2 years and creates an exponential
model for estimating the stock price based on the
number of weeks after the first public offering.
Answer:
the 3rd one
Step-by-step explanation:
i just took the test
Based on the model produced by the scatterplot, log of stock prices is calculated from the scatter plot and 10 is raised to the power of the result to obtain the estimated stock price. Hence, a reasonable estimate for the stock price would be ; $185.05
From the scatter plot model :
Week number, x = 95log y = 0.0022(95) + 2.0583
log y = 2.2673
y = estimated stock priceRaise the power of both sides to the power of 10
[tex]y = 10^{2.2673} = 185.054 [/tex]
Therefore, a reasonble estimate for the stock price would be $185.05

Answer:
[tex]\Huge\boxed{74}[/tex]
Step-by-step explanation:
Hello There!
First things first, we need to find the value of x
If you didn't know the measures of supplementary angles add up to equal 180 so we can use this equation to solve for x
180 = 2x + 3x - 5
step 1 combine like terms
2x + 3x = 5x
now we have
180 = 5x - 5 step 2 add 5 to each side
-5 + 5 cancels out
180 + 5 = 185
now we have 185 = 5x
step 3 divide each side by 5
5x/5=x
185/5=37
we're left with x = 37
Now we want to plug in 37 into x for angle A
angle a = 2(37)
2*37=74
so we can conclude that angle A = 74

Find m∠ J
Use a calculator. Enter only a number
Answer:
26 degrees.
Step-by-step explanation:
We are given
Side KL length which is 46. (let call that side j).Side JL length which is 93( let call that side k).Angle L=90.We are trying to find angle measure of j.
Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.
[tex] \tan(x) = \frac{opp}{adj} [/tex]
[tex] \tan(x) = \frac{46}{93} [/tex]
since we are trying to find the angle measure apply inverse trig function
[tex] \tan {}^{ - 1} ( \frac{opp}{adj} ) [/tex]
Plug 46 for opp and 93 for adj.
[tex] \tan {}^{ - 1} ( \frac{46}{93} ) [/tex]
which is about 26 degrees.
solve x^2-8x-9=0 using completing the square (show the work)
Answer: x=9,-1
Step-by-step explanation:
First, we are gonna start out with finding two numbers that multiply to equal -9 and add up to equal -8
Those numbers would be -9 & 1
-9+1=-8
-9x1=-9
Now we have
(x-9)(x+1)
x-9=0 x+1=0
+9 +9 -1 -1
x=9 x=-1
