Well,
This is pretty straightforward.
If we start with 6°C, and we want a temperature 10°C less than that, we can just subtract 10 from 6.
6 - 10 = -4
-4°C is 10°C less than 6°C.
40º
7) In this problem, we can see that both tangent lines to that circle come from the same point O.
So, we can write out the following considering that there is one secant line DO and one tangent line to the circle AO
Answer:
Step-by-step explanation:
This question is asking us to find where sin(2x + 30) has a sin of 1. If you look at the unit circle, 90 degrees has a sin of 1. Mathematically, it will be solved like this (begin by taking the inverse sin of both sides):
On the left, the inverse sin "undoes" or cancels the sin, leaving us with
2x + 30 = sin⁻¹(1)
The right side is asking us what angle has a sin of 1, which is 90. Sub that into the right side:
2x + 30 = 90 and
2x = 60 so
x = 30
You're welcome!
Answer:
35
Step-by-step explanation:
14+21=7(2+3)=7(5)=35
Hi there!

I believe your answer is:
14

Here’s why:
- I have graphed the given solution in a program. The parabola intercepts at (4,0) and (14,0).
- The x-intercepts of a parabola are the solutions to the equation. The other solution should be 14.
