Answer:
B
Step-by-step explanation:
We want to find the equation of a line with a slope of 3 that includes the point (0, 5).
We can use the slope-intercept form, given by:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
Notice that the given point (0, 5) is already the y-intercept. So, b = 5.
By substitution, we acquire:
[tex]y=3x+5[/tex]
Hence, our answer is B.
Answer:
B: y=3x+5
Step-by-step explanation:
the line crosses the y axis at point 5, the slope is 3

I DONT NEED THE ANSWER TO A, I JUST NEED B
Answer:
The composition g(f(x)) is:
[tex]g(f(x))=4x^{2}-12x+10[/tex]
Step-by-step explanation:
b) g(f(x)) is a function composition.
So we will have:
[tex]g(f(x))=(f(x))^{2}+1[/tex]
[tex]g(f(x))=(2x-3)^{2}+1[/tex]
[tex]g(f(x))=4x^{2}-12x+9+1[/tex]
[tex]g(f(x))=4x^{2}-12x+10[/tex]
Here:
a is 4
b is -12
c is 10

How to prove this using trig identities?
(Tan B + Cot B)^2 = sec^2B + csc^2B
Thanks and please shows steps. I will vote best answer and helpful and do more.
Step-by-step explanation:
tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)
= (sin2B + cos2B)/[(cosB)(sinB)]
= 1/[(cosB)(sinB)]
= (1/cosB)(1/sinB)
= (secB)(cscB)
what is the perimeter of figure B ?
Answer:
35 for perimeter of b
122.5 for perimeter of a
Step-by-step explanation:
To find the perimeter, you add all of the values of the outside of the shape together. Since 12+9+9+5 = 35, the answer is 35.
Okay, so what you have to do is set up a proportion for a to b. To do that, you have to have a fraction where a is the numerator and b is the denominator. 7/2 equals x/35. Then cross multiply
7*35 = 2x
x = 122.5 :)
Answer:
The perimeter is 35.
Step-by-step explanation:
To find perimeter, add all the sides together.
9 + 9 + 5 + 12 = 35
The perimeter is 35.

The quantity of an element is decaying over time such that the amount of material
any time is given by the function F(t) = 6700(0.7)3t. Write an equivalent function
of the form F(t) = abt.
The equivalent function in the form y = ab^x is [tex]F(t)=2,298.1(0.7)^t[/tex]
Exponential functions:Give the exponential function in a general sense as y = ab^x
Given the exponential function [tex]F(t) = 6700(0.7)^{3t}[/tex]We are to write it in the form [tex]f(t) = ab^t[/tex]
This can be further expressed as;
[tex]F(t) = 6700(0.7)^{3t}\\F(t) = 6700(0.7^3)(0.7^t)\\F(t)=2,298.1(0.7)^t[/tex]
Hence the equivalent function in the form y = ab^x is [tex]F(t)=2,298.1(0.7)^t[/tex]

Please help me find the value of x in the rectangle ABCD
Answer:
x = 52
Step-by-step explanation:
Hello there!
All of the angles in a rectangle are right angles
if a right angle has a measure of 90 degrees then we can find x by subtracting the given angle from 90
90 - 38 = 52 so we can conclude that x= 52
Step-by-step explanation:
Each angle in a quadrilateral is 90⁰ therefore 38⁰+x=90⁰
hence x=90⁰-38⁰ which gives you 52⁰

Answer:
m<BDC = 60 degrees
Step-by-step explanation:
m<EBD is 120, m<EBC = 180 (it's a straight angle) so m<DBC = 180-120= 60 degrees.
All angles in a triangle add up to 180. 60+60+x=180. 180-120=x=60.

Write the function.
y=
Answer:
Step-by-step explanation:
x y Difference (d)
-1 -1 -
0 -0.5 -0.5 - (-1) = 0.5
1 0 0 - (-0.5) = 0.5
2 0.5 0.5 - 0 = 0.5
3 1 1 - 0.5 = 0.5
There is a common difference (d) = 0.5
Therefore, table represents a linear function.
Let the equation of the linear function is,
y = mx + b
Here, m = Slope and b = y-intercept
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] will be,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Two points from the given table are (-1, -1) and (0, -0.5)
m = [tex]\frac{-0.5-(-1)}{0-(-1)}[/tex]
m = 0.5
Y-intercept of the line 'b' = -0.5 (Value of y at x = 0)
Therefore, equation of the line will be,
y = 0.5x - 0.5

Calculate the geometric mean of 12 and 20
Answer:
The Geometric mean of two numbers is the square root of their product.
Given numbers are 12,20.
Geometric mean = √(12*20)
= √240.
= 15.49.
= 15.5.
The geometric mean of 12 and 20 is 4√15.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 3 + 3x + 4y = 7 is an expression.
We have,
The geometric mean of a and b is √(ab).
Now,
a = 12 and b = 20
so,
The geometric mean of 12 and 20.
= √(12 x 20)
= √240
= 4√15
Thus,
The geometric mean of 12 and 20 is 4√15.

Connor invested $8,000 in an account paying an interest rate of 82% compounded
monthly. Henry invested $8,000 in an account paying an interest rate of 8 %
compounded daily. After 5 years, how much more money would Henry have in his
account than Connor, to the nearest dollar?
Answer:
Connor would have $83.37 more than Henry.
Step-by-step explanation:
Connor:
Initial investment= $8,000
Interest rate= 8.2% = 0.082/12= 0.00683
Number of periods= 12*5= 60 months
Henry:
Initial investment= $8,000
Interest rate= 8% = 0.08/365= 0.00022
Number of periods= 365*5= 1,825 days
To calculate the future value, we need to use the following formula on each investment:
FV= PV*(1+i)^n
Connor:
FV= 8,000*(1.00683^60)
FV= $12,035.35
Henry:
FV= 8,000*(1.00022^1,825)
FV= $11,951.98
Difference= 12,035.35 - 11,951.98= $83.37
Connor would have $83.37 more than Henry.
