Answer:

A=166 in²

Step-by-step explanation:

A=2(wl+hl+hw)

A= 2(5x7+4x7+5x4)

A=2(35+28+20)

A=2(83)

A=166 in²

Q 7 = 6

Q 8= -x + 2

Step-by-step explanation:

150 x 60 = 9,000 every hour

9000 x 24 = 216,000 every day

216000x 365 = 78,840,000 every year

Answer:

Hour: 9,000 people

Day: 216,000 people

Year: 78,840,000 people

Step-by-step explanation:

In order to solve this, you need to identify how many minutes there are in an hour, a day, and a year:

Hour: 60 minutes

Day: 60 minutes × 24 hours = 1,440 minutes

Year: 60 minutes × 24 hours × 365 days = 525,600 minutes

Now, you need to multiply each of these numbers by 150 to find how many people are born every hour, day, and year:

Hour: 60 minutes × 150 people = 9,000 people

Day: 1,440 minutes × 150 people = 216,000 people

Year: 525,600 minutes × 150 people = 78,840,000 people

Answer:

x = 8

Step-by-step explanation:

4(8) + 6(5) = 62

32 + 30 = 62

62 = 62

Answer:

x = 8

Step-by-step explanation:

y = 5 and 4x + 6y = 62

4x + 30 = 62

Subtract 30 from each side:

4x + 30 - 30 = 62 - 30

4x = 32

Divide each side by 4:

4x ÷ 4 = 32 ÷ 4

x = 8

Answer:

1, 2 * 3^3 * 17

2, 8

Answer:

(C)

Step-by-step explanation:

looking from the slope: f'(2) is negative

f(2)=0

the curve concave upward: f''(2) is positive

f'(2)<0

f(2)=0

0<f''(2)

f'(2)<0<f''(2)

The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.

A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.

Given:

The coordinate of the graph is shown in figure  (2, 0),

As we can see from the graph, the slope: f' (2) is negative (Downwards)

Again, from the graph

f(2) = 0

Thus, the curve concave upward: f'' (2) is positive (upward)

f' (2)<0

f (2)=0

0 < f'' (2)

f' (2) < 0 < f'' (2)

Therefore, f' (2) < 0 < f'' (2) is true in the given graph.

Answer: length = 8cm

Width = 4cm

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Since the length of a rectangle is twice as long as the width of the rectangle, then the length will be: = 2 × x = 2x

Note that, Area of a rectangle = Length × Width

Therefore,

2x × x = 32

2x² = 32

Divide both side by 2

2x²/2 = 32/2

x² = 16

x = ✓16

x = 4

Therefore, width = 4cm

Since length = 2x

Length = 2 × 4cm = 8cm

Check: length × width = Area

8cm × 4cm = 32cm²

Step-by-step explanation:

First I set up a formula to solve how many ounces of salt there were out of 30,      

x/30=20/100, I crossed multiplied and got 5/30, next, I set up the same formula for how many ounces of salt there were out of 25, x/25=30/100, I got 7.5, the last thing I did was add them both together leading me to the answer 12.5 or 12 1/2. Hope this helps! Please say if I am wrong.

x = y + 6

y + 6 = x

y = x - 6

f^-1(x) = x - 6

Answer:

Step-by-step explanation:

use  SOH CAH TOA

Sin = Opp / Hyp

Cos = Adj / Hyp

Tan = Opp / Adj

then we know the adjacent side and the angle, and want to find the Hyp, so use  CAH

Cos(60) = ( 8[tex]\sqrt{3}[/tex]  / 3 ) / Hyp       ( cos(60) = 1/2 )

Hyp = (8[tex]\sqrt{3}[/tex] / 3) / (1/2)

Hyp = 2 ((8[tex]\sqrt{3}[/tex] / 3)

Hyp = 16[tex]\sqrt{3}[/tex] / 3

x =  16[tex]\sqrt{3}[/tex] / 3

Now use SOH

Sin (60) = Opp / 16[tex]\sqrt{3}[/tex] / 3      ( sin(60) = [tex]\sqrt{3}[/tex]/2 )

(16[tex]\sqrt{3}[/tex] / 3)([tex]\sqrt{3}[/tex]/2) = Opp

16 * 3 / 6  = Opp

8 = Opp

y = 8
