Answer:

put the numbers that are x into the equation. you always try to find y in this problem

Step-by-step explanation:

y=x+8

the first x is 0 so we do

y= 0+8

y=8

and you keep repeating this where x=1 and x= 2

Answer:

m=3 n=6

Step-by-step explanation:

top diagonals are congruent

9 = 3m

solve for m

m = 3

bottom diagonals are congruent

m + 8 = 2n -1

plug in 3 for m

3 + 8 = 2n -1

solve for n

11 +1 = 2n

12 = 2n

n=6

Step-by-step explanation:

Top left box

f(x) = 2x² + 4

g(x) = 2f(x) - 3

Top right box

f(x) = 2x² + 4

g(x) = 2f(x) + 3

Bottom left box

f(x) = 2x² - 4

g(x) = 2f(x) - 3

Bottom right box

f(x) = 2x² - 4

g(x) = 2f(x) +3

Answer:

B. cos(x+y) + cos(x-y)= 2cosx.cosy

The time required to get a total amount of $13,200.00 with compounded interest on a principal of $7,000.00 at an interest rate of 5.5% per year and compounded 12 times per year is 11.559 years. (about 11 years 7 months)

Answer:

t = 11.559 years

Given Data

(about 11 years 7 months)

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 5.5/100

r = 0.055 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(13,200.00/7,000.00) / ( 12 × [ln(1 + 0.055/12)] )

t = ln(13,200.00/7,000.00) / ( 12 × [ln(1 + 0.0045833333333333)] )

t = 11.559 years

Line CB touches circle A only at one point (point B), hence CB is a tangent.

A circle is the locus of a point such that its distance from a fixed point (center) is always constant.

When a line intersects a circle in exactly one point the line is said to be tangent to the circle

Hence since Line CB touches circle A only at one point (point B), hence CB is a tangent.

Answer:

Parallel: -3

Perpendicular: 1/3

Step-by-step explanation:

First I would convert the equation into slope-intercept form to more easily identify the slope:

[tex]y+4=-3x-3\\ y=-3x-7[/tex]

Slope-intercept form is defined as y=mx+b where m is the slope and b is the y-intercept so we can identify the slope of this line as -3.  

When a line is parallel to another line, this means that they have the same slope, therefore the slope of the line parallel to the equation is -3.  

Perpendicular lines will have slopes that are negative reciprocals of each other, the negative reciprocal of -3 is 1/3; therefore, the slope of the line perpindicular to the equation is 1/3.

Answer:

parallel slope = -3

perpendicular slope: [tex]\sf \bold{\frac{1}{3} }[/tex]

Explanation:

comparing with y = m(x) + b      [ "m" is the slope, "b" is the y-intercept ]

Parallel/Tangent slope:

m₁ = m₂                (same)

Perpendicular/Normal slope:

m₁ * m₂ = -1           (negatively reciprocal)

⇒ Here parallel slope:

⇒ Here perpendicular slope:

The area of the rectangle and triangle are 48 mm² and 24 mm² respectively.

The area is the amount of space occupied by a two dimensional shape or object.

Area of rectangle = length * width = 6 mm * 8 mm = 48 mm²

Area of triangle = (1/2) * base * height = 0.5 * 6 * 8 = 24 mm²

The area of the rectangle and triangle are 48 mm² and 24 mm² respectively.

Answer:

SA = 696cm^2

Step-by-step explanation:

First we need to identify the shapes

There are 3 rectangles and 2 triangles

Now the individual surface area for each shape

20 x 10 = 200 (1 rectangle)

1/2(12 x 8) = 48 (1 triangle)

Now we add them together

(200 x 3) + (48 x 2) = 696
