Hello,
Please, see the attached file.
Thanks.
Answer:
Q5: S.A = 216 cm²
Q6: S.A = 254 cm²
Step-by-step explanation:
Q5:
Surface area of a cube = 6a²
a = 6 cm
Plug in the value of a
Surface area of the cube = 6(6²)
= 6(36)
S.A = 216 cm²
Q6:
Given:
Length (L) = 9 cm
Width (W) = 4 cm
Height (H) = 7 cm
Required:
Surface area
Solution:
Surface area of the rectangular prism = 2(LW + LH + HW)
Plug in the values
S.A = 2(9*4 + 9*7 + 7*4)
= 2(36 + 63 + 28)
= 2(127)
S.A = 254 cm²
5/12 hour = 1 piano solo's
15/12 hour = 3 piano solo's
Simplifying 15/12 hours we get:
<u>1.25 hours also known as 1 hour 15 minutes</u>
a) Local maximum values of g are: 0 and 3
b) The values at which g has local maximum are : -2 and 2
<h3>What is a maximum point?</h3>
A maximum point is the point at which the gradient of the curve changes from positive to negative.
Analysis:
The inverted v-curves all have maximum values and they are two.
The one at x = -2 and the one at x = 2 for in both cases their maximum values are y = 0 and y = 3 respectively.
