It looks like this is a square pyramid net, and to find the surface area you need to know the base and height. By looking at the image 5 ft is the height and the base is 3 ft.
The surface area of the square pyramid is <u>40.32</u>
hope this helps!
A ) h = -16 t² + 135 t + 76
Let : h = 0
0 = - 16 t² + 135 t + 76
B ) t 1/2 = (-b+/- √ ( b² - 4 ac ) / ( 2 a )
t 1/2 = (-135 - √(18,225 + 4,864))/ (-32) = ( - 135 - 151.95) / (- 32)=
= (-286.95) / (- 32) = 9.967 ≈ 9.0 s ( other solution is negative )
Answer:
2) 0 = -16 t² + 135 t + 76; 9 s
By definition of <em>linear</em> functions and the comparison with the attached figure, the function that represents the graph is y = (7/15) · x + 4, - 6 ≤ x ≤ 9.
<h3>What kind of function represents the graph?</h3>
Graphically speaking, <em>linear</em> functions represent lines and we see that the line seen in the figure presents two bounds, the points (- 6, 0) and (9, 7). <em>Linear</em> functions are characterized by slope and intercept:
y = m · x + b (1)
Slope
m = (7 - 0)/[9 - (- 6)]
m = 7/15
Intercept
b = 4

Answer:
$3.06
Step-by-step explanation:
First we need to calculate the mark up
The mark-up rate is 150% = 1.5 as a decimal
New price = original price + original price * markup rate
= 61.20 + 61.20* 1.50
= 61.20 + 91.80
= 153
The new price is 153.00
Commission is the price times his commission rate
commission = price* .02
= 153*.02
= 3.06
Neil will make 3.06 on the sale of the table
The answer would be $15
All you need to do is multiply each one by .4 and see which one equals 6.
15 x .4 =6
Hope this helps!
