Answer:
a)The sunglasses hit the ground at t=0 seconds
b)The maximum height h(t) = 1600feet
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the polynomial function
h(t) = -16 t² + 1600 ...(i)
Differentiating equation (i) with respective to 't' , we get
Equating zero
⇒ -32t =0
⇒ t =0
The sunglasses hit the ground at t=0 seconds
<u><em>Step(ii):-</em></u>
Again differentiating with respective to 't', we get
The maximum height at t=0
h(t) = -16 t² + 1600
h(t) = 1600feet

The wide of the model should be approximately 5.194 inches
Step-by-step explanation:
You are building a scale model of a fishing boat
- The boat is 62 ft long
- The boat is 23 ft wide
- The model will be 14 in long
We need to find how wide should it be
∵ The boat is 62 feet long
∵ The model of the boat is 14 inches long
- That means 14 inches represents 62 feet
By using the ratio method
→ Actual (ft) : Model (in)
→ 62 : 14
→ 23 : x
By using cross multiplication
∵ 62 × x = 23 × 14
∴ 62 x = 322
- Divide both sides by 62 to find x
∴ x ≅ 5.194
∵ x represents the wide of the model
∴ The wide of the model is approximately 5.194 inches
The wide of the model should be approximately 5.194 inches

The rewritten form of the given expression using the fewest terms is; 3x + 6.
<h3>What is the rewritten form of.the expression using the least possible terms?</h3>
It follows from the task content that the given expression is to be rewritten using the fewest terms.
Since the given expression is;
( −2x − 13 ) + ( 19 + 5x )
By getting rid of the parentheses; we have;
-2x - 13 + 19 + 5x
By collecting like terms; we have;
-2x + 5x - 13 + 19
3x + 6
Therefore, the required rewritten form of the given expression is; 3x + 6.
