Which problem can be solved with the equation 1.75+(-1.75)=0?

Answer:

A.) 24.08 seconds

B.) 825.42 metres

Step-by-step explanation:

function of time is given as

h ( t ) = − 4.9 t 2 + 118 t + 115 .

Where a = -4.9, b = 118, c = 115

Let's assume that the trajectory of the rocket is a perfect parabola.

The time t the rocket will reach its maximum height will be at the symmetry of the parabola.

t = -b/2a

Substitute b and a into the formula

t = -118/-2(4.9)

t = 118/9.8

t = 12.041 seconds

Since NASA launches the rocket at t = 0 seconds, the time it will splash down into the ocean will be 2t.

2t = 2 × 12.041 = 24.08 seconds

Therefore, the rocket splashes down after 24.08 seconds.

B.) At maximum height, time t = 12.041s

Substitute t for 12.041 in the function

h ( t ) = − 4.9 t 2 + 118 t + 115

h(t) = -4.9(12.041)^2 + 118(12.041) + 115

h(t) = -4.9(144.98) + 118(12.041) + 115

h(t) = -710.402 + 1420.82 + 115

h(t) = 825.42 metres

Therefore, the rocket get to the peak at 825.42 metres

Answer:

The equation is (i guess):

300*y = 23*t  -41,180

This is a linear equation, where y represents the population, and t represents time (in years)

Now, to find the gradient, we must derive the function y with respect to the time.

then we can write:

y = (23/300)*t - (41,180)/300.

now, remember that when we have:

y = a*x^n

we also have:

dy/dx = n*a*x^(n-1)

then in this case, we have:

dy/dt = (23/300) + 0

now we pass aain the 300 to the right:

300*dy/dt = 23.

d(300*y)/dt = 23

what does this mean?

Thie mean that for each unit of that t increases, we have an increase of 23 units in 300*y.

Answer: I dont have the full answer, but this is what i could figure out.

Step-by-step explanation:

3.01 gallon per minute

60 minutes in an hour

3.01 times 60= 180.6

180.6 times 1.85= 334.11

I do not know what to do after this, I wish I could help more, but I hope someone or yourself can figure out the rest. Good luck!

Answer:

Step-by-step

i) a² - 2ab + b² = (a + b)²

a² = p² ;     a  = p

b² = 16 = 4²  ;        b = 4

2ab = 2*p*4 = 8p

p² - 8p + 16 = (p - 4)²

ii) a² + 2ab + b² = (a +b)²

a² = 121x² = (11x)²                 ;  b² = 4y² = (2y)²

2ab = 2 * 11x * 2y = 44xy

121x² + 44xy + 4y² = (11x + 2y)²

Answer:

dy/dx = (x + 1)(x-4)/(x-1)(x+4)[1/(x+1) + 1/(x-4) -1/(x-1) -1/(x+4)

Step-by-step explanation:

Here, we want to find the derivative using logarithmic differentiation.

What we will do here is to first take the natural logarithm of both sides, then we proceed to differentiate afterwards.

Answer:

85

Step-by-step explanation:

There are three angles in a triangle

Since it is a right triangle one angle is 90 degrees

We are given one angle is 5 degrees

Let the third angle be x

The sum of the angles of a triangle is 180

x+5+90 =180

Combine like terms

x+95 = 180

Subtract 95 from each side

X+95-95 = 180-95

x = 85

Step-by-step explanation:

The required tools are a compass and straightedge. A pencil or other drawing tool will also be useful (or you can use the marker in the compass).

Generally, follow the applicable directions. The specific directions vary, depending on the construction you want to do. Numerous web sites and videos can show you step-by-step. (Search for "construction of ...") for whatever you're trying to construct.

To construct a circle (or part of a circle), set the compass to the appropriate width, place the pointed end on the center of the circle, and rotate the marker in a circle around that point, taking care to ...

To construct a line through two points, align the edge of the straightedge with the two points, and make a mark along that edge using your marking tool. (You may find that you need to make a slight adjustment in your alignment to account for the width of the marker).

All other constructions use combinations of these skills.

Answer:

P = 10W + 28

Step-by-step explanation:

Let L be the original length of the garden

W  be the original width of the garden

If Mr. Kim's rectangular garden is four times as long as it is wide, then L = 4W

If he is going to enlarge it  by extending each side 7 feet, then;

The new length l = (4W + 7) feet

The new width will be w =(W+7) feet

Perimeter of the rectangular gerden P = 2(l+w)

l and w are the new length and width

Substituting l = 4W+7 and w = W+7 into the formula;

P = 2(4W+7+W+7)

P = 2(5W+14)

open the parenthesis

P = 10W + 28

Hence the perimeter of Mr. Kim's garden after it is  enlarged is given by the expression P = 10W + 28

Answer:

1) ∫₀¹ 2π x (x − x²) dx

4) ∫₀¹ π ((√y)² − y²) dy

Step-by-step explanation:

The solid formed is a hollow, upside down cone.  We can either use washer method or shell method to find the volume.

If we use washer method, the thickness of the washers is dy.  The outside radius is R = x₂ = √y, and the inside radius is r = x₁ = y.

Therefore, the volume of each washer is:

dV = π (R² − r²) t

dV = π ((√y)² − y²) dy

The total volume is the sum of all washers from y=0 to y=1.

V = ∫ dV

V = ∫₀¹ π ((√y)² − y²) dy

If we use shell method, the thickness of each shell is dx.  The radius of each shell is r = x.  The height of each shell is h = y₂ − y₁ = x − x².

Therefore, the volume of each shell is:

dV = 2π r h t

dV = 2π x (x − x²) dx

The total volume is the sum of all shells from x=0 to x=1.

V = ∫ dV

V = ∫₀¹ 2π x (x − x²) dx
