Answers
Answer:
1
Step-by-step explanation:
sec⁴x-tan⁴x÷sec²x + tan²X
= sec⁴x-tan⁴x/sec²x + tan²X
= (sec²x)²-(tan²x)²/sec²x + tan²X
Using the difference of two square
a² - b² = (a+b)(a-b)
(sec²x)²-(tan²x)² = (sec²x + tan²X)(sec²x - tan²X)
= (sec²x)²-(tan²x)²/sec²x + tan²X
= (sec²x + tan²X)(sec²x - tan²X)/sec²x + tan²X
= sec²x - tan²X
Also sec²X = 1 + tan²X
Substitute
= 1 + tan²X- tan²X
= 1
Hence the value of the expression is 1

Line DCE is parallel to line AB
a) Find the size of angle ABC
b) Find the size of angle DCA
c) Calculate the size of angle ACB
Answers
Answer:
Angle DCA = Angle CAB. (Alternate Interior Angle)
Angle DCA = 68°
Angles(DCA + ACB + BCE) = 180°. (Linear Pair)
Angle ACB + 68° + 33° = 180°
Angle ACB = 79°
Therefore,
Angle ABC = 33°. (Alternate Interior Angle)
Determine if the following is discrete or continuous data: The function c =
12p gives the cost c based on the number of pizzas p.
Answers
Answer:
Step-by-step explanation:
Remember, discrete data is separate, by itself, but continuous data goes on and can have numbers in between. So this problem is c = 12p is the cost of pizzas, you can have 1 pizza, 2 pizzas, 10 pizzas, 30 pizzas, etc., but you can't have 2.1314552 pizzas or 4.5, etc., so the data is discrete. Think of the graph, you would not connect the dots if you were graphing this data.

Step 2: Solve for t
[Subtraction Property of Equality] Isolate t terms: 7 = 2 + 2t[Subtraction Property of Equality] Isolate t term: 5 = 2t[Division Property of Equality] Isolate t: 5/2 = tRewrite: t = 5/2Answer:
t = ⁵⁄₂ or 2.5Explanation:
3t + 7 = 2 + 5t
Simplify both sides of the equation3t + 7 = 5t + 2
Subtract 5t from both sides3t + 7 − 5t = 5t + 2 − 5t
−2t + 7 = 2
Subtract 7 from both sides−2t + 7 − 7 = 2 − 7
−2t = −5
Divide both sides by -2
−2t / -2 = −5 / -2

A pizzeria charges $8 for a large cheese pizza plus $2 for each additional topping.
m = ______ b = ______
Answers
Answer:
m = 2
b = 8
Step-by-step explanation:
m, the slope, will be 2. This is because $2 is charged for each topping.
b, the y intercept, will be 8. This is because there is a standard charge of $8 for a cheese pizza without any toppings.
The y intercept can be represented by the point (0, 8), where 0 represents the amount of toppings and 8 represents the price of $8.
So, m = 2 and b = 8

Answers
Answer:
We're told that Marcy collected 160 out of 10 cans. That could be expressed as 160/10, but given that the numerator and denominator are both divisible by 10, we can factor that out and express it as 16/1. You can also express it as ratio of 16:1 cans collected to cans intended.
Answer:
As a ratio, this is expressed as
✔ 160 to 100
As a fraction, this is expressed as
✔ 160/100
As a percent, this is expressed as

Kylie and Matt are driving out of town, leaving from the same house in
different cars. Matt drives at a rate of 40 miles per hour. Matt drives 50
miles before Kylie begins traveling. Kylie drives at a rate of 50 miles per
hour. .
Answers
Answer:
They will meet in 5 hours.
Step-by-step explanation:
This question should ask how long until they meet.
Matt drives at a rate of 40 miles per hour. Matt drives 50 miles before Kylie begins traveling.
So the total distance for Matt is given by:
[tex]M(t) = 40t + 50[/tex]
Kylie drives at a rate of 50 miles per hour.
When he starts(at position 0), Matt will be already at 50. So Kylie's equation is given by:
[tex]K(t) = 50t[/tex]
How many hours until they meet?
This is t for which:
[tex]K(t) = M(t)[/tex]
So
[tex]50t = 40t + 50[/tex]
[tex]10t = 50[/tex]
[tex]t = \frac{50}{10}[/tex]
[tex]t = 5[/tex]
They will meet in 5 hours.
