Answer:
f(x) = -x2 + 3x + 13
f(-10) = - (-10)2 + 3(-10) + 13
f(-10) = 20 - 30 + 13
f(-10) = 3

Answer:
60.28.
Step-by-step explanation:
We need the sine function because we are given the opposite side and we need the hypotenuse.
sin 71 = 57 / x
Cross multiply
x * sin 71 = 57
x = 57 / sin 71
= 60.28.

Answer:
x=-6
Step-by-step explanation:
Answer:
[tex]x=-6[/tex]
Step-by-step explanation:
[tex]5x+8+3x+4=-40+4[/tex]
⇒ Subtract 4 from both sides:
[tex]5x+8+3x+4-4=-40+4-4[/tex]
[tex]5x+8+3x=-40[/tex]
⇒ Combine like terms:
[tex]5x+3x=8x[/tex]
[tex]8x+8=-40[/tex]
⇒ Subtract 8 from both sides:
[tex]8x+8-8=-40-8[/tex]
[tex]8x=-48[/tex]
⇒ Divide both sides by 8:
[tex]\frac{8x}{8}=\frac{-48}{8}[/tex]
[tex]x=-6[/tex]

Looking at the two terms, 7a4b2c2 and 14abc6, what is the GCF do the coefficients?
Greatest Common Factor is also shortened as G.C.F . Greatest Common Factor can be used as the greatest or highest number that divides exactly into two or more numbers.
The GCF for the coefficients is 7. Option A is the correct option.
From the question, we are given two terms 7a4b²c² and 14abc⁶
The coefficient for 7a4b²c² = 7
The coefficient for 14abc⁶ = 14
Solving for the GCF,
The factors of 7 are: 1, 7
The factors of 14 are: 1, 2, 7, 14
Then the greatest common factor is 7.
Therefore, the GCF for the coefficients is 7 . Option A is the correct option.

What is the quotient of 4.644 x 10^8 and 6.45 x 10^3 expressed in scientific
notation?
Answer:
7.2 x 10^4
Step-by-step explanation:
The quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation is 7.2 x 10⁴.
What is the quotient of division?The quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation, is calculated as follows;
(4.644 x 10⁸) / (6.45 x 10³) = (4.644 / 6.45) x (10⁸ / 10³)
Calculating the division:
= 72,000
Now, we need to express the result in scientific notation. Move the decimal point to the left until there is only one non-zero digit to the left of the decimal point.
= 72,000
= 7.2 x 10⁴
So, the quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation is approximately 7.2 x 10⁴.

How might the crisis in biodiversity lead to a food crisis for humans?
Answer:
Hi and heres your answer!
Step-by-step explanation:
The crisis of biodiversity will lead to a food crisis for humans because:
1.No varieties in certain foods like plants and animals that are healthy
2.The Less food there is,more animals go extinct which means humans will go extinct too.
and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)
