Answer:

s(t) = -4.9t² + 39.2t

Step-by-step explanation:

Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²

Given

g = -4.9m/s²

v0 = 39.2m/s

s0 = 0m (the initial height)

On substituting into the formula;

s(t) = gt² + v0t + s0

s(t) = -4.9t² + 39.2t + 0

s(t) = -4.9t² + 39.2t

This gives the equation that models the height

Answer:

x = -6

Step-by-step explanation:

[tex]x+\frac{2}{3}=\frac{8}{9}x\\\\x = \frac{8}{9}x - \frac{2}{3}\\\\x - \frac{8}{9}x= -\frac{2}{3}\\\\\frac{9}{9}x-\frac{8}{9}x=\frac{2}{3}\\\\\frac{1}{9}x=-\frac{2}{3}\\\\x=-\frac{2}{3}*\frac{9}{1}\\\\x=(-2)*3\\\\x = -6[/tex]

Answer:

x = [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

Given

x + [tex]\frac{2}{3}[/tex] = [tex]\frac{8}{9}[/tex] ( multiply through by 9 to clear the fractions )

9x + 6 = 8 ( subtract 6 from both sides )

9x = 2 ( divide both sides by 9 )

x = [tex]\frac{2}{9}[/tex]

Answer:

1.2 times or 20%

Step-by-step explanation:

Given the function ; f(x) = 830(1.2)^x

This is an exponential function ;

Recall the general form of an exponential function ; f(x) = ab^x ;

Where a = Initial value ; b = growth rate

Hence, b = 1.2

Also, b = 1 + r

1.2 = 1 + r

r = 1.2 - 1

r = 0.2

r = 0.2 * 100% = 20%

The slope of the line is 1

Step-by-step explanation:

Given:

Number of males = h

Number of females = (h-2)

Total number of visitors = 80

To find:

The value of h.

Solution:

We have,

Number of males = h

Number of females = (h-2)

So, the total number of visitors is:

[tex]Total=h+(h-2)[/tex]

[tex]Total=2h-2[/tex]

It is given that the total number of visitors is 80. So,

[tex]2h-2=80[/tex]

[tex]2h=80+2[/tex]

[tex]2h=82[/tex]

Divide both sides by 2.

[tex]h=\dfrac{82}{2}[/tex]

[tex]h=41[/tex]

Therefore, the correct option is D.

Answer:

111 m²

Step-by-step explanation:

A rectangle is a quadrilateral (has four sides and four angle) with two pairs of parallel sides. Opposite sides of a rectangle are equal to each other. Also all the angles of a rectangle are 90° each.

The area of a rectangle = length * width

For rectangle 1, length = 12 m, width = 3 m

Therefore area of rectangle 1 = length * width = 12 m * 3 m = 36 m²

For rectangle 2, length =(12 m - 3 m - 3 m) = 6 m, width =(15 m - 10 m) =5 m

Therefore area of rectangle 2 = length * width = 6 m * 5 m = 30 m²

For rectangle 3, length = 15 m, width = 3 m

Therefore area of rectangle 3 = length * width = 15 m * 3 m = 45 m²

Area of composite shape = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Area of composite shape = 36 m² + 30 m² + 45 m² = 111 m²

Answer:

5.218

Step-by-step explanation:

Since 2, ten thousandths place, is less than 5, the thousandths place stays the same.

It would be 5.218

Answer:

1.06 or 1 1/15

Step-by-step explanation:

So, basically what we need to do is reverse the steps.

So now it goes like this:

We start with 1 5/6(1.83)

Then we add 7/18(0.389)

Then we multiply by 1 1/5(1.2)

Then finally, we divide by 2 1/2(2.5)

This will get us our answer. So:

1.83+0.389 = 2.219

2.219*1.2 = 2.6628

2.6628/2.5 = 1.06

This is 1.06 in decimal form, or 1 1/15 in fraction form

Hope this helps!

This can also be double checked, if you plug it into the orginal equation:

1.06, then you multiply by 2.5: 1.06*2.5= 2.6628

2.6628, then you divide by 1.2: 2.6628/1.2= 2.219

Then finally, 2.219 and subtract 7/18: 2.219-0.389= 1.83

So we have double checked, and our answer is still 1.06.

Answer:

g(5) = -19

Step-by-step explanation:

Substitute 5 for x in the equation

Plug in 5 for the x's and get g(x)=-3(5)-4 and then -15-4 which is -19 so g(x)=-19

Answer:

Step-by-step explanation:

This is one of those questions that  has no answer. The first one is not a triangle. 3 and 6 = 9. Two of the legs have to longer than the third. 9 is not greater than 10.

So there is no answer. However leave a note of there is a mistake in what you wrote and I'll come back.

The other two are right (the middle one) and the last one is acute.

Answer:

$2250

Step-by-step explanation:

selling the ring at 100% of $1500 would equal 1500 and yield no profit

therefore, you must sell the ring at 150% (where 100% covers the cost and the additional 50% provides the profit) of 1500

1.5 x 1500 = 2250
