Answer:
-1
Step-by-step explanation:
We need to find the value of tan² 70° -sec² 70°.
We know that,
[tex]\sec^2\theta-\tan^2\theta=1[/tex] ...(1)
We can write the given expression as :
tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)
=-(sec² 70°-tan² 70°)
Using identity (1)
=-(1)
= -1
Hence, the value of the given expression is -1.

Then you put them back into fraction form.
help me plzzzzzzz i will give u 50 points
Balanced means both sides are equal.
Add the left side: there are 7 1's which equal 7
Adding the right side you have 2 + r
They have to equal each other so the equation is 7 = 2 + r

Step-by-step explanation:
Y is inversely proportional to the square of x. If Y = 3 when x = 3, then Y =
ş, when x is
?
Answer:
It will be same the value of second Y
Answer:
y = [tex]\frac{27}{x^2}[/tex]
Step-by-step explanation:
Assuming you require the equation of proportion.
Given y is inversely proportional to x² , then the equation relating them is
y = [tex]\frac{k}{x^2}[/tex]
To find k use the condition if y = 3, then x = 3, that is
3 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )
27 = k
y = [tex]\frac{27}{x^2}[/tex] ← equation of proportion

2. (4a - 8b + 12c) (-5/2) Simply using distributive property and combining like terms
Answer:
-10a + 20b - 30c
Step-by-step explanation:
(4a - 8b + 12c)(-5/2)
=(4a + - 8b + 12c)(-5/2)
=(4a)(-5/2) + (-8b)(-5/2) + (12c)(-5/2)
=-10a + 20b -30c

1. During the month of March, it rained 1.8 inches. In April, it rained 1.75 inches.
How much did it rain over these 2 months?
It rained 3.55 over the 2 months. First you would have to add 1.8 and 1.75 because that how much they rained each month. Then you’ll have to add them together to find the answer which is 3.55. So the total inches of rain it rained both months together was 3.55 inches.

A website lists homes for sale in a suburban town. The site provides information including neighborhood, selling
price, age of the home in years), number of bedrooms, and whether the home has a garage. Which of the variables
is a categorical variable?
neighborhood
selling price
age of the home
number of bedrooms
Answer:
neighborhood
Step-by-step explanation:
Variables can be classified as categorical(qualitative) and quantitative.
Categorical variables:
Its variables are labels(for example, good/bad, yes/no,...)
Quantitative variables:
It's variables are numbers.
In this question:
The only variable which the answer is a label is the neighborhood. So this is the answer.

If x = 15 cm and y = 2/5 cm, what is the length of z?
Answer:
option b. 5 cm
Step-by-step explanation:
y² + x² = z²
(2/5)²+(/15)²=z²
2×5+15=z²
10+15=z²

What is the equation of the line that passes through the points (0,2) and (2,4)?
Step-by-step explanation:
[tex] \underline{ \underline{ \text{Given \: points}}} : [/tex]
( 0 , 2 ) ( 2 , 4 )Let the points ( 0 , 2 ) and ( 2 , 4 ) be A and B respectively. Let A ( 0 , 2 ) ⤑ ( x₁ , y₁ ) & B ( 2 , 4 ) ⤑ ( x₂ , y₂ ). Now , Using two point form of the equation of striaght line , we have :
[tex] \boxed{ \sf{ y - y_{1} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} (x - x_{1})}}[/tex]Plug the values :

Answer:
b
Step-by-step explanation:
Identify the true statement about the given patterns.
Pattern C: 4, 5, 6, 7, 8, ...
Pattern D: 2, 3, 4, 5, 6, ...
The terms in Pattern D are 2 more than the terms in Pattern C.
The terms in Pattern D are 1 more than the terms in Pattern C.
The terms in Pattern C are 2 times the terms in Pattern D.
The terms in Pattern C are 2 more than the terms in Pattern D.
Answer:
The 4th option i.e. 'The terms in Pattern C are 2 more than the terms in Pattern D' is correct.
Step-by-step explanation:
Given the patterns
Pattern C: 4, 5, 6, 7, 8, ...
Pattern D: 2, 3, 4, 5, 6, ...
If we carefully analyze, it is clear that terms in the pattern C are 2 more than the terms in Pattern D.
In other words, if we add 2 in each term of the Pattern D, we will get the pattern C.
For example,
Pattern D: 2, 3, 4, 5, 6, ...
Now, add 2 in each term of Pattern D
i.e.
2+2 = 4
3+2 = 5
4+2 = 6
5+2 = 7
6+2 = 8
It is clear that we get the results 4, 5, 6, 7, 8 when we add 2 in each term of Pattern D.
As 4, 5, 6, 7, 8 represent Pattern C. Therefore, we conclude that the terms in Pattern C are 2 more than the terms in Pattern D.
Hence, the 4th option i.e. 'The terms in Pattern C are 2 more than the terms in Pattern D' is correct.
Answer:
4, 5, 6, 7, 8 when we add 2 in each term of Pattern D

12 and k is 94 please help
Answer:
12k = 84 (Product means multiply)
k = 7
Step-by-step explanation:
12k = 84
12k ÷ 12 = 84 ÷ 12
k = 7
Answer:
K = 82
94-12=84
therefore k= 82 because, 12+82=94
Earl attaches a wire from the top of a 16-foot flagpole and stakes it to the ground 12 feet from the base
of the pole. How many feet long is the wire?
16 Ft
Answer:
16 feet
Step-by-step explanation:
We are told that:
Earl attaches a wire from the top of a 16-foot flagpole and stakes it to the ground
Therefore, we can conclude that the Length of the wire = Length of the flagpole
The length of the wire = 16 ft
Therefore, the wire is 16 feet long.

Ice cubes trays each contain 12 cubes of ice. If t represents the number of trays, and c
represents the number of cubes, find an equation that relates t and c.
Answer:
c = 12 * t
Step-by-step explanation:
The only equation that relates t and c would be the following...
c = 12 * t
This is because the total number of cubes that exist depends on how many available trays exist. Therefore, creating a positive correlation relationship between these two variables. Since each tray contains 12 cubes, 12 is therefore multiplied by the number of trays to get the total number of cubes. This means that the more trays available the more cubes that are created.
Evaluate the function for x = 3.5 f(x)=[2.5x]
a 8.75
b 8
c 9
Answer:
The correct option is a. 8.75.
Step-by-step explanation:
Given:
f(x)=[2.5x] .............................. (1)
Where;
x = 3.5
The function can be evaluated by substituting x = 3.5 into equation (1), we have:
f(3.5) = 2.5 * 3.5
f(3.5) = 8.75
This implies the value of the function is 8.75. Therefore, the correct option is a. 8.75.
