Answer:
Step-by-step explanation:
Let
D(t) = the distance to the safe zone (measured in meters)
t = time (measured in seconds)
<u>Given:</u>
Rachel's rate = 24 meters per second
At 
seconds 
meters
<u>Find:</u> D(t)
Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.
Hence, the function expression is
To find b, substitute and 
So,
Answer:
A = 104 ft²
Step-by-step explanation:
We're given that the width of the rectangle is 8 so that's the value of w. All we have to do is just plug in 8 into the equation:
A=w²+5w
A=(8)²+5(8)
A=64+40
A = 104 ft²
Answer:
<h3>(a) 3^9</h3>
Step-by-step explanation:
<h3> IN EXPONNETIAL FORM :</h3>
<h3>– (a^m× a^n) = (a^m+n)</h3>
<h3>3^4 × 3^5 = 3^4+5 = </h3>
<h2>3^9 </h2>

The product if a number if it is multiplied by 1 is the same number itself.
Given:
Product:
The product meaning in math is a number that you get to by multiplying two or more other numbers together.
Rules:
1) 1 is the multiplicative identity, if we multiply any of the number with 1 we get the same number as the answer to that.
2) So as per the rule if we multiply any of the whole numbers with 1 we get the same number.
Example:
= 1 * 155
= 155
= 1 * 688
= 688
= 1 * 97
= 97
