A function assigns the values. The range of the function will be between (-∞,10].

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The given function f(x)=10-x² is a parabolic function that is negative, therefore, will open downwards. Now, the range of the function can be found as,

f(x)=10-x²

y=10-x²

y-10 = -x²

-y+10 = x²

-y + 10 = 0

y = 10

Thus, the range of the function will be between (-∞,10].

Len [333]

Answer:

<h2>12 feet 8 inch long cast a shadow</h2>

Step-by-step explanation:

A person 6 feet tall standing 18 feet away a lamppost cast a 9 foot shadow.

than move 4 feet than total distance is 22 feet  

According to trigonometry rule make 30 degree angle

tan\left ( 30\ \right )^{o}=\frac{p}{b}

\left ( \frac{1}{\sqrt{3}} \right )=\left ( \frac{x}{18+4} \right )

or

x\sqrt{3}=22

than

x=\frac{22}{\sqrt{3}}

=12feet 8 inch answer

A canoe traveled Downstream with the current and went a distance of 15 miles in three hours. On the return trip, the canoe trave
coldgirl [10]

Answer:

1 mile/hr

Step-by-step explanation:

Let the Speed of the boat still in water = a

Speed of the current = b

We know from this formula that speed = distance/time

Hence,

A canoe traveled Downstream with the current and went a distance of 15 miles in three hours.

Downstream = a + b = 15/3

a + b = 5 .........Equation 1

On the return trip, the canoe traveled Upstream against the current. It took 5 hours to make the return trip.

Upstream = a - b = 15/5

a - b = 3 ..............Equation 2

Combining both Equation together

a + b = 5 .........Equation 1

a - b = 3 ..............Equation 2

Subtracting Equation 2 from Equation 1

2b = 2

b = 2/2

b = 1miles/hr

Since b = speed of the current which can also be called rate of the current, the rate of the current = 1 miles/hr

What does d equal ?? ​
Vlad1618 [11]

Answer:

<h2>d = 23</h2>

Step-by-step explanation:

∠IHE and ∠GHF are vertical angles.

Vertical angles have the same measures (are congruent).

Therefore, if m∠IHE = d + 44 and m∠GHF = 4d - 25, then we have the equation:

d + 44 = 4d - 25         <em>subtract 44 from both sides</em>

d + 44 - 44 = 4d - 25 - 44

d = 4d - 69            <em>subtract 4d from both sides</em>

d - 4d = 4d - 4d - 69

-3d = -69          <em>divide both sides by (-3)</em>

-3d/(-3) = -69/(-3)

d = 23
