Just draw the graphs, and you should find y = 10x² is the only graph narrower than the given one.
Answer:
30 - 12x or 6(5 - 2x)
Step-by-step explanation:
Given expression:
First, let us simplify the expression inside the parentheses;
- ⇒ 4[5 + (-3x)] + 10
- ⇒ 4[5 - 3x] + 10
Then, let us open the parentheses by simplifying the distributive property;
- ⇒ 4[5 - 3x] + 10
- ⇒ 20 - 12x + 10
Finally, let us simplify the expression by adding 10 to 20.
- ⇒ 20 - 12x + 10
- ⇒ 30 - 12x
[Optional] Factor the expression by putting the expression in parentheses.
Since 6 is divisible to all the terms in the expression, we can divide 6 to all the terms in the expression and take "6" outside the parentheses.
- ⇒ 6(30/6 - 12x/6)
- ⇒ 6(5 - 2x)
Therefore, the simplified expression is 30 - 12x or 6(5 - 2x).
Answer:
C. right triangle only
Step-by-step explanation:
Other triangles use other laws such as law of cosines or sines to solve them. Right triangles exclusively use SOH-CAH-TOA because side opposite to 90 degree is always hypotenuse.
<u>Answer: </u>
The equation of the circle with center (0, 1) and a radius of 10 is
<u>Solution:
</u>
Equation of circle whose center (h, k) and radius r is given as,
---- eqn 1
From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.
Hence we get, h = 0 ; k = 1; r = 10
By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as
On Simplifying we get
Expand using the formula
Hence equation of the circle with center (0, 1) and a radius of 10 is
