The value of 8th term of this sequence is,
⇒ a (8) = - 49,152
What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Given that;
Consider the first four terms of the sequence are,
⇒ -3, -12, -48, -192, . . .
Here, Common ratio is,
⇒ - 12 / - 3
⇒ 4
Thus, The sequence are in Geometric sequence.
Hence, The value of 8th term of this sequence is,
⇒ a (8) = - 3 × (4)⁸⁻¹
⇒ a (8) = - 3 × 4⁷
⇒ a (8) = - 3 × 16,384
⇒ a (8) = - 49,152
Thus, The value of 8th term of this sequence is,
⇒ a (8) = - 49,152

he slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the slope is 4 .
Step-by-step explanation:
can i have brainliest
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x - 3 ← is in slope- intercept form
with slope m = 4
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{4}[/tex] , then
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute (4, 8) into the partial equation
8 = - 1 + c ⇒ c = 8 + 1 = 9
y = - [tex]\frac{1}{4}[/tex] x + 9 ← equation of perpendicular line

A number is decreased by 15% and the resulting number is then increased by 20%. That final number is what percent of the original number?
Answer:
The final final number becomes 102 % of the original number
Step-by-step explanation:
Let the initial number be 100
After decreasing 15%, the new number is 100-15% of 100 = 85
The resulting number is then increased by 20%. The new number will be
85 + 20% of 85 = 85 + 17 = 102
The final final number becomes 102/100 * 100 percent of the original number
The final final number becomes 102 % of the original number

Tony and Edwin each built a rectangular garden. Tony’s garden is half as long and 6 times as wide as Edwin’s garden. If the area of Edwin’s garden is 400 square feet, what is the area of Tony’s garden?
Answer:
1200 ft²
Step-by-step explanation:
Let's say that Edwin's garden was 400 feet long and 1 foot wide.
If Tony's garden is half as long and 6 times as wide, then we need to divide 400 in half and multiply 1 by 6 to get the dimensions of Tony's garden.
400/2 = 200 ft
1 × 6 = 6 ft
Area of Tony's Garden = 6 x 200 = 1200 ft²

If a point is randomly selected from the rectangular area of the graph, what is the probability that it will be in the blue region?
Round answer to the nearest whole percentage?
A. 49%
B. 59%
C. 69%
D. 79%
Answer:
D. 79%
Step-by-step explanation:
Took the the on USA Test prep
If a point is randomly selected from the rectangular area of the graph, the probability that it will be in the blue region is 79%.
What is the probability?The ratio of the number of favorable outcomes to the total number of outcomes of an event is known as probability.
It is given that, the length=20, the width=10, and the radius of half circle=10.
Calculate the area of the rectangle.
Knows the area of the rectangle is the product of length and width.
So,
[tex]\Rightarrow \text{Area of rectangle}=\text{10}\times \text{20} \\ \Rightarrow \text{Area of rectangle}=200 \\[/tex]
Calculate the area of the half-circle.
Knows the area of the half-circle[tex]=\frac{\pi r^{2} }{2}[/tex].
So,
[tex]& \Rightarrow \text{Area of half circle}=\frac{3.14\times 10\times 10}{2} \\ & \Rightarrow \text{Area of half circle}=\frac{314}{2} \\ & \Rightarrow \text{Area of half circle}=157 \\[/tex]
Calculate the probability that it will be in the blue region.
Knows the formula for the probability, [tex]\text{Probability}\left( \text{Event} \right)=\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}[/tex]
So,
[tex]& \Rightarrow \text{Probability}=\frac{\text{157}}{200} \\ & \Rightarrow \text{Probability}=0.78539 \\ & \therefore \text{Probability }\%=79\% \\[/tex]
Thus, the correct answer is an option (D). i.e., 79%.

If you borrow $200 for 12 years at
an annual interest rate of 2%, how
much will you pay altogether
Step-by-step explanation:
What is the Percentage?
percentage, a relative value indicating the hundredth parts of any quantity.
Given,
If you borrow $200 for 12 years at an annual interest rate of 2%
We need to find 2% of 200.
Firstly we have to convert 2% to a decimal number by dividing by 100.
2/100=0.02
Now we have to multiply 0.02 with 200
0.02×200=4
For a month it is four.
Now we are calculating for the year
4×12=48
So now the interest amount is 48.
Now add 48 and 200
48+200
248
Hence, If you borrow $200 for 12 years at an annual interest rate of 2%, then we have to pay $248 altogether.

For what values of x is g(x) > f(x)?
O A 0 < x < 2 and x > 4
OB. 2
C. X > 4
OD. X > 2
Answer:
Step-by-step explanation:
Given the functions f(x) = 2x^2 + 2 and g(x) = 2^x+1 + 2
If g(x) > f(x)
2^(x+1) + 2 > 2x^2 + 2
2^x*2 + 2 >2x^2 + 2
2^x*2 >2x^2
2^x > x^2
2^x - x^2 > 0
g(x) > f(x) over the interval 0 < x < 2 and x > 4.
