Answer:

3.3 seconds

Step-by-step explanation:

v(t) =140t/5t - 6 where v is velocity

The time, t when, v = 44 ft/s

Put v = 44 ft/s in the equation :

44 = 140t / 5t - 6

44(5t - 6) = 140t

220t - 264 = 140t

-264 = 140t - 220t

-264 = - 80t

Divide both sides by 80

264 / 80 = 80t/80

3.3 = t

Hence, automobile will reach a velocity of 44 ft /s after 3.3 seconds

The elapsed time would the automobile reach a velocity of 44 Feet per second is 3.3 seconds

Since

An automobile's velocity, starting from a complete stop, is v(t) =140t/5t - 6 where v is measured in feet per second.

So, the time should be

[tex]44 = 140t \div 5t - 6[/tex]

44(5t - 6) = 140t

220t - 264 = 140t

-264 = 140t - 220t

-264 = - 80t

3.3 = t

Hence, The elapsed time would the automobile reach a velocity of 44 Feet per second is 3.3 seconds

Answer:

22 feets

Step-by-step explanation:

From the diagram attached :

We have two similar triangles which can be related proportionally :

Hence ;

Mitchell's height / distance from mirror = cliff height / cliff distance

Michelle's height = 5.5

Michell's distance from mirror = 4

Cliff height = h

Cliff distance from mirror = 16

We have ;

5.5 / 4 = h / 16

Cross multiply :

4 * h = 5.5 * 16

h = 88 / 4

h = 22 feets

Answer:

Amount of paper need = 140 cm²

Step-by-step explanation:

Given:

Length of rectangular prism = 5 cm

Width of rectangular prism = 5 cm

Height of rectangular prism = 4 cm

Base of triangular side = 5cm

Height of triangular side = 6 cm

Find:

Amount of paper need

Computation:

Amount of paper need = Curved surface area of rectangular prism +  Curved surface area of square pyramid

Amount of paper need = 2h(l + b) + 4[Area of triangle]

Amount of paper need = 2h(l + b) + 4[(1/2)(b)(h)]

Amount of paper need = (2)(4)(5 + 5) + 2[(5)(6)]

Amount of paper need = (8)(10) + 2[30]

Amount of paper need = 80 + 60

Amount of paper need = 140 cm²

No, it does not.

Step-by-step explanation:

A linear function of x will form a straight (non-vertical) line on a graph.

This is caused directly by the equation

y = ax + b

For some constant a and b, which means that the rate of change is constant.

24+8-(7x6)

Answer:

C

Step-by-step explanation:

Given

x² - 36 = 0 ( add 36 to both sides )

x² = 36 ( take the square root of both sides )

x = ± [tex]\sqrt{36}[/tex] = ± 6

That is x = - 6, x = 6 → C

Answer:

33.7 ft

Step-by-step explanation:

We solve the above question using Trigonometric function of Tangent

tan θ = opposite/adjacent

θ = 56°

Opposite = 50 ft

Adjacent = x

Cross Multiply

tan 56 = 50 ft/x

Cross Mulitiply

tan 56 × x = 50ft

x = 50ft/tan 56

x = 33.725425842 ft

Approximately = 33.7 ft

The bird must travel 33.7 ft to meet the worm

Answer:

x > 17.5

Step-by-step explanation:

So we are given that; [tex]\frac{4x}{7} > 10[/tex]

=> First multiply 7 on each side of "="

4x = 70

=> Now divide 4 on each side

=> x > 17.5

I think the title is missing from the graph

Answer:

Y-intercept maybe? since the given function doesn't have a point where x = 0

Or it could also be the x and y-axis are not labeled
