98 isnt a prime, which means that it is a composite number
Answer:
99.33ft^2
Step-by-step explanation:
The surface area of a square pyramid is expressed as;
TSA = a²+2a√a²/4 + h²
Given that
a = 5ft
h = 7ft
Substitute
TSA = 5²+2(5)√5²/4 + 7²
TSA = 25+10√25/4 + 49
TSA = 25 + 10√(221/4)
TSA = 25 + 10(√55.25)
TSA = 25 + 10(7.433)
TSA = 25 + 74.33
TSA = 99.33ft^2
Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2

<h3><u>Answer :- </u></h3>
• 1 / 3
<h3><u>Explanation :- </u></h3>
<u>As </u><u>we </u><u>know</u><u> </u><u>that </u><u>,</u><u> </u>
If a dilation produces a smaller figure then ,
0 < Scale factor < 1 .
So then ,
Case 1 ) -2 => The scale factor must be a positive number .
Case 2 ) 1 / 3 => 0 < 1/3 < 1 => Is a possible scale factor .
Case 3 ) 1 => This scale factor does not produce a smaller figure , It produces the same figure .
Case 4 ) 4 => This scale factor produces a larger figure .
<h3>• Hence, the answer is 1/3 .</h3>

Answer:
3. y = 3·4^x
4. y = 24·0.5^x
5. y = 45·0.9^x
Step-by-step explanation:
Each table appears to represent an exponential function. Such a function can be written in the form ...
y = a·b^x
where 'a' is the value of y when x=0, and 'b' is the ratio of the values of y when x=1 and x=0.
__
3. a = 3. b = 12/3 = 4
y = 3·4^x
__
4. a = 24. b = 12/24 = 0.5
y = 24·0.5^x
__
5. a = 45. b = 40.5/45 = 0.9
y = 45·0.9^x
