Answer:

t = 4 seconds

Step-by-step explanation:

The height of a soccer ball as a function of time is given by :

[tex]h(t)=-16t^2+48t+64[/tex]

We need to find the time when the ball hit the ground i.e. h = 0

Put h = 0 in above equation. So,

[tex]-16t^2+48t+64=0\\\\16(-t^2+3t+4)=0\\\\-t^2+3t+4=0[/tex]

It is a quadratic equation such that,

t = -1 s and t = 4 s

Neglecting -1 s, the ball will hit the ground after 4 seconds.

Answer:

-9x^2+x-10

Step-by-step explanation:

A= 5*6 - 3*2

 = 30 - 6

 = 24 in^2

first solve for the entire shaped. Even with the non shaded area.

5×6=30in

now solve for the non shaded area.

3×2=6

since you dont want the non shaded subtract it from the entire shape so

30-6=24in

the area of the shaded region is 24in

Answer:

13.74

Step-by-step explanation:

Answer:

13.74

Step-by-step explanation:

Add 0.4+0.3 = 0.7, so the equation now looks like this: 12.95+0.7+0.09

Add 0.7 + 0.09 = 0.79, so the equation now looks like this: 12.95 + 0.79

Add 12.95 + 0.79, so now you are left with: 13.74

Answer:

- 13

Step-by-step explanation:

[tex]log \frac{ {a}^{6} {b}^{6} }{ {c}^{7} } \\ \\ = log( {a}^{6} {b}^{6} ) - log {c}^{7} \\ \\ = 6log \: a + 6log \: b - 7log \: c \\ \\ = 6(2) + 6( - 3) - 7(1) \\ \\ = 12 - 18 - 7 \\ \\ \therefore \: log \frac{ {a}^{6} {b}^{6} }{ {c}^{7} } = - 13[/tex]

Answer:

C. 9cm, 9cm, 19cm

Step-by-step explanation:

Answer: 13 is a rational number

Step-by-step explanation: By definition, a rational number is a number q that can be written as a fraction in the form q=a/b where a and b are integers and b≠0. So, 1/3 is rational because it is exactly what you get when you divide one integer by another.

Answer: 97

Step-by-step explanation:

394 / 4 = 98.5, so the 4 numbers must be around 98.5.

97 + 98 + 99 + 100 = 394

Answer:

the Pythagorean theorem states:  

a^2 + b^2 = c^2  in your case a=24 and c=40

Step-by-step explanation:

24^2 + b^2 = 40^2

24x24 + b^2 = 40x40

(576 + b^2 = 1600)  

b^2 = 1600 - 576

b^2 = 1024

b= √1024

b = 32

Final answer: 32

The length of b is 32 units in triangle ΔABC.

Pythagoras theorem states that, a right-angled triangle, the square of the one side is equal to the sum of the squares of the other two sides.

a² + b² = c²

Given data as :  a=24 and c=40

Substitute the values of a and c in the equation,

24² + b² = 40²

24x24 + b² = 40x40

(576 + b² = 1600)  

b² = 1600 - 576

b² = 1024

b= √1024

b = 32

Hence, the length of b is 32 units.

Answer: 3/10 probability

Step-by-step explanation:

We are telling the probability with tenths, so we can say that the probability of the meteoroid landing on Earth is 3/10.

If the surface area of the world is approximately 7/10, or 70 percent, water, there is approximately 3/10, or 30 percent, chance of the meteoroid hitting land.

I'm pretty sure, at least ^_^

270º clockwise transformation:

The 270° clockwise transformation of a point (x,y) is:

(x,y) -> (-y,x)

Thus, as we just apply the rule in this conceptual question, the correct answer is given by:

F. (x, y) = (-y, x)

Answer:

Infinitely many solutions.

Step-by-step explanation:

4(x-8)+9=4x-23

4x-32+9=4x-23

4x-23=4x-23

infinitely many solutions.

The 3 inside angles of a triangle need to equal 180 degrees.

Add the 3 together to equal 180:

X + 2x + x+ 14 = 180

Combine like terms:

4x + 14 = 180

Subtract 14 from both sides:

4x = 166

Divide both sides by 4

X = 41.5

Answer:

Fraction form: x = 83/2

Decimal form: x = 41.5

Step-by-step explanation:

The 3 angles inside the triangle will always add up to 180 degrees.

So that gives us the equation:

x + 14 + x + 2x = 180

Combine like terms:

4x + 14 = 180

Subtract on both sides:

4x = 166

Divide:

41.5

Answer:

the answer would be c

Step-by-step explanation:

≤ less than or equal to sign

2by some number take away 4 is less than or equal to 26

Answer:

the answer is c

Step-by-step explanation:

twice a number

we don't know the number so it's x

so 2x

then we decrease it by 4

so 2x-4

then Less than or equal to is ≤

then you put 26

so 2x-4≤26

Answer:

A. Translate 1 to the right, reflect over the x-axis, then scale vertically by a factor of 1

Step-by-step explanation:

Initially:

We have the function [tex]y = k(x)[/tex]

k(x + 1)

To translate a function k(x) a units to the left, we find k(x + a).

Thus, k(x+1) is the translation of k(x) 1 unit to the left.

-k(x+1)

Multiplying a function by a negative constant is the same as reflecting it over the x-axis, and then scaling it vertically by a factor of the constant.

Thus:

The answer is given by option A:

A. Translate 1 to the right, reflect over the x-axis, then scale vertically by a factor of 1

Answer:

We will split the trapezoid into right angle triangle and rectangle

Traingle with base 3cm and height 10 - 6 = 4cm

Area of traingle

       = [tex]\frac{1}{2}*base *height = \frac{1}{2} * 3 * 4 = 6cm^{2}[/tex]

Area of rectangle with sides 6cm and 3cm

       =[tex]6 * 3 = 18cm^{2}[/tex]

Therefore, area of the trapezoid

       = [tex]6+18 = 24cm^{2}[/tex]

Area of the semi circle with radius 3/2 = 1.5cm

        = [tex]\frac{1}{2}\pi r^{2} = \frac{1*\pi *1.5*1.5}{2} = 1.125\pi cm^{2}[/tex]

[tex]Total area = 24 + 1.125\pi =27.53cm^{2}[/tex]
