Answer:
Step-by-step explanation:
Don't use 0 as a substitute for θ. 0 is always 0.
cosθ = -5/(2√15)
secθ = 1/cosθ = -2√15/5
The exact value of sec θ is -8.6/5.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
Point(-5, -7).
Here, x= -5 and y= -7
So, r = √x² + y²
r= √(-5)² + (-7)²
r= √25 + 49
r = √74
r= 8.6
So, sec θ= H/ B
= r/x
= 8.6/ (-5)
= -8.6/ 5

Each TTF site bought a new rope bridge for 4,500. TTF will make monthly payments of $350 until the bill is paid. Write an equation for the unpaid balance B after m monthly payments
Answer: 4500 - 350m
Step-by-step explanation:
From the question, we are informed that each TTF site bought a new rope bridge for 4,500 and that TTF will make monthly payments of $350 until the bill is paid.
The equation for the unpaid balance B after m monthly payments will be:
= 4500 - 350m
where me = number of months
For example, if the number of months used is 4 months, the unique balance will be:
= 4500 - 350m
= 4500 - 350(4)
= 4500 - 1200
= 3300

1) Divide £10 into the ratio 2 : 3
Answer:
£4 and £6
Step-by-step explanation:
Let the common multiplier of the given ratios be x.
So, 2x and 3x are the two parts of £10.
Hence,
2x + 3x = 10
5x = 10
x = 10/5
x = 2
2x = 2*2 = 4
3x = 3*2 = 6
Hence, the two parts of £10 are £4 and £6.

(5x – 10x2) /(14x - 7)
Answer:
- [tex]\frac{5x}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5x-10x^2}{14x-7}[/tex] ← factor out 5x in the numerator and 7 in the denominator
= [tex]\frac{5x(1-2x)}{7(2x-1)}[/tex] ← factor out - 1 on the numerator
= [tex]\frac{-5x(2x-1)}{7(2x-1)}[/tex] ← cancel the common factor (2x - 1)
= - [tex]\frac{5x}{7}[/tex]
