Prove the following relations:
1) (1 - cos²A) (1 + tan²A) = tan²A
Step-by-step explanation:
(1 - cos²A) (1 + tan²A) = tan²A
(sin²A)(sec²A) = tan²A
(sin²A)(1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → Proved

You are a graphic artist. You are given an image that is 1.2 inches tall and 2.1 inches wide. Your customer wants the image enlarged to create a banner 7 feet wide. Calculate how tall your banner should be to create a proportional image. Remember to include correct units in your answer!
Height / Width = 1.2in / 2.1in
Height / Width x / 84in (7feet)
Solve for X using cross multiplation
2.1x = 1.2 * 84
2.1x = 100.8
x (height) = 48 inches or 4 feet.
The Lucas numbers are defined by the recursive formula t1 = 2, t2 = 1, tn = tn - 1 + tn - 2, where n âN and n > 2. What are the first 9 Lucas numbers?
The first two are given to you, [tex]t_1=2[/tex] and [tex]t_2=1[/tex]. Use the recursive formula to get the 3rd term; then use the 2nd and 3rd terms to get the 4th; and so on.
Since the n-th Lucas number is the sum of the previous two Lucas numbers, you have
[tex]t_3 = t_2 + t_1 = 1 + 2 = 3[/tex]
[tex]t_4 = t_3 + t_2 = 1 + 3 = 4[/tex]
[tex]t_5 = t_4 + t_3 = 4 + 3 = 7[/tex]
[tex]t_6 = t_5 + t_4 = 7 + 4 = 11[/tex]
[tex]t_7 = t_6 + t_5 = 11 + 7 = 18[/tex]
[tex]t_8 = t_7 + t_6 = 18 + 11 = 29[/tex]
[tex]t_9 = t_8 + t_7 = 29 + 18 = 47[/tex]
What is the slope of the line whose equation is 2x+3y = -12?
Answer:
slope = - [tex]\frac{2}{3}[/tex]
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 )
Given
2x + 3y = - 12 ( subtract 2x from both sides )
3y = - 2x - 12 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x - 4 ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]

Answer:
x + y =5 .......eqn (1)
x - y =3 .......eqn(2)
using substitution method
x + y = 5
-
x - y = 3
0 + 2y=2
y = 2/2
y = 1
substitute y in egn(1)
x + 1 = 5
x = 5-1
x = 4
then (x, y) = (4,1)
What is a solution to this mathematical equation?
3.76 x 4.64 = x
x= ???
Answer:
x= 17.4464
Step-by-step explanation:
1) Multiply the numbers
3.76 · 4.64 = x
17.4464 = x
2) Move the variable to the left
17.4464 = x
x = 17.4464
Step-by-step explanation:
you don't have a calculator ? even your computer or your smart phone have calculator apps.
just type it in : 3.76 × 4.64
and the result is : 17.4464 = x

Answer:
If you rotate the triangles so that they look the same, one side of both of them are labeled. This gives you the fraction 9/12, or 3/4. The smaller triangle is 3/4th of the larger one. If the larger triangle has 4 on one side, then let's make the equation 3/4 = y/4. The length of y is 3. :)

Write the equation in slope intercept form. what are the slope and y-intercept? -3x - 10y = 7
Answer:
Slope: = 3/10x
y-intercept: = -7/10
Step-by-step explanation:
10y = -3x - 7
y = -3/10x - 7/10
Slope: = 3/10x
y-intercept: = -7/10

Select the equation that is true.
A.0.84 x 6 = 0.504
B. 0.84 x 6 = 5.04
C. 0.84 x 6 = 50.4
D. 0.84 x 6 = 504
Answer:
0.84 x 6 = 5.04
Step-by-step explanation:
5.04 is the answer.
Answer:
Answer B is correct
Step-by-step explanation:
We want to multiply 6 and 0.84
First you have to forget about decimals and multiply those two numbers
084
×6
-----------------
= 504
And then consider about the number of decimal places. According this sum you have 2 decimal places ( 0.84 )
And now you can write the answer as
= 5.04
Hope this helps you.
