Answer:

288

Step-by-step explanation:

To solve, we need to find the area of the four triangle sides and add that to the square base's area.

Area of triangle sides: base * height * 0.5

Area of square base: base * height

Substitute the values

8 * 14 * 0.5 = 56

There are four of these sides, so the area of all the triangles is 224.

The square base is 8 * 8, or 64

Add these two values together.

64 + 224 = 288

Thus, the answer is 288

the length of a rectangle is 6in.more than than its width .Its area is 50 sq.in Find the width of the rectangle....

yulyashka [42]

L=6+W
A=LW
sub 6+W for L
A=(6+W)(W)
expand
oh, A=50
50=W²+6W
minus 50 both sides
0=W²+6W-50
we gots to use quadratic formula
for
aW²+bW+c=0
W= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
we got
a=1
b=6
c=-50

W= $\frac{-(6)+/- \sqrt{(6)^2-4(1)(-50)} }{2(1)}$
W= $\frac{-6+/- \sqrt{36+200} }{2}$
W= $\frac{-6+/- \sqrt{236} }{2}$
W= $\frac{-6+/- 2\sqrt{59} }{2}$
W= $-3+/- \sqrt{59}$

W= $-3+ \sqrt{59}$ or W= $-3- \sqrt{59}$
aprox
W=-10.6811 or W=4.68115
can't be negative width

width=4.68115 or -3√59

Agata [3.3K]

Answer:

It's the first option.

Step-by-step explanation:

y = cos x transformed to cos (x - π/2) moves the graph π/2 units to the right.

Multiplying by 3 to give 3 cos(x - π/2) stretches the graph 3 units parallel to the y-axis and adding 3 to this moves the graph up 3 units.

So the required equation is y = 3(cos x - π/2) + 3.
