answer: 5x + 5y

Considering a quadratic equation, it is found that:

Considering the height in feet, it is given by:

h(t) = -4.9t² + v(0)t + h(0)

In which:

In this problem, we have that h(0) = 6, v(0) = 16, hence the equation is given by:

h(t) = -4.9t² + 16t + 6

Which is a quadratic equation with coefficients a = -4.9, b = 16, c = 6. Hence the maximum height is found as follows:

[tex]\Delta = b^2 - 4ac = 16^2 - 4(-4.9)(6) = 373.6[/tex]

[tex]h_{MAX} = -\frac{\Delta}{4a} = -\frac{373.6}{-4(4.9)} = 19.06[/tex]

The maximum height of the volleyball is of 19.06 feet.

It hits the ground at the roots, hence:

The solutions are:

[tex]x_1 = \frac{-16 + \sqrt{373.6}}{-9.8} = -0.34[/tex]

[tex]x_2 = \frac{-16 - \sqrt{373.6}}{-9.8} = 3.6[/tex]

Time is a positive measure, hence:

The volleyball will hit the ground after 3.6 seconds.

The range of the data is the difference between the largest data value and the smallest data value.

Therefore, the ranges are:

Boys:  10 - 3 = 7

Girls:  9 - 5 = 4

So the boys have a larger range than the girls.

To calculate the mean, add up all the data values then divide by the number of values.

[tex]\textsf{Mean of Boys}=\dfrac{3+6+7+7+8+8+8+8+9+10}{10}=\dfrac{74}{10}=7.4[/tex]

[tex]\textsf{Mean of Girls}=\dfrac{5+6+6+6+7+7+7+8+8+9}{10}=\dfrac{69}{10}=6.9[/tex]

So the boys have a higher mean than the girls.

Answer: 960^3 cm or 960 cubic centimeters

Step-by-step explanation:

Cubic because measuring 3 dimensions.

32x45 = area of given face

32x45= 1440

height of water = 10 cm

so,

area of given face x 10 =

32x45x10 or lxwxh (Volume)

so

1440x10= 14,400

1440x8= 11,520

so 14,400 - 11,520 = 2880

V of three plants = 2880

so, 2880/3 = volume of one plant

2880/3=960

V of singe plant = 960 units ^ 3

The difference in volumes represents the total volume of three plants, so answer should be divided by 3.

Answer:  one plastic water plant volume =  960 cm³

Step-by-step explanation:

Total volume = Water Volume + 3 plants volume

Total Volume = 32 cm x 45 cm x 10 cm = 14 400 cm³

Water volume = 32 cm x 45 cm x 8 cm = 11 520 cm³

3 Plants volume = 14,400 cm³ - 11,520 cm³ = 2880 cm³

1 Plant volume = 2,880 cm³ : 3 = 960 cm³

Point x is located at ( 2,5)

When reflecting across the y axis the x value remains the same.

The reflection is at y -2, from -2 to the location of z (-5) is a difference of 3 units.

Add 3 to the reflection line -2 + 3 = 1 , the new y value would be 1.

the new location would be (2,1)

Step-by-step explanation:

Hey there!

2x + 3x = 20 + x

5x = 20 + x

20 + x = 5x

SUBTRACT x to BOTH SIDES

5x - x = 20x + x - x

5x - 1x = 20x + 1x - 1x

SIMPLIFY IT!
4x = 20

DIVIDE 4 to BOTH SIDES

4x/4 = 20/4

SIMPLIFY IT!
x = 20/4

x = 5

Therefore, your answer is: x = 5

Isolate the absolute-value term:

2 |3x - 5| - 4 = 12

2 |3x - 5| = 8

|3x - 5| = 4

Recall the definition of absolute value:

[tex]|x| = \begin{cases}x & \text{if }x \ge0\\-x&\text{if }x<0\end{cases}[/tex]

We consider two cases:

• If 3x - 5 ≥ 0, then |3x - 5| = 3x - 5, and the equation resolves to

3x - 5 = 4

3x = 9

x = 3

• Otherwise, if 3x - 5 < 0, then |3x - 5| = -(3x - 5) = -3x + 5, hence

-3x + 5 = 4

-3x = -1

x = 1/3

Answer:

x = 4

Step-by-step explanation:

When you have a coefficent in front of a logarithm function, you can take the argument to the power of that coefficient. For example, the 3 in front of the logarithm can be brought into the argument, and you can take 'x' to the third power. You get:

[tex] log_{4}( {x}^{3} ) = log_{4}(32) + log_{4}(2) [/tex]

When you add logarithms, it is equivalent to multiplying their arguments:

[tex]log_{4}( {x}^{3} ) = log_{4}(32 \times 2) = log_{4}(64) [/tex]

Since both sides are log base 4, the arguments must equal each other:

[tex] {x}^{3} = 64[/tex]

[tex]x = \sqrt[3]{64} = 4[/tex]

here it is, this is ur answer x=4

The pattern is +5 then -2 alternatively .

A pattern is a repeated arrangement of numbers, shapes, colors and so on. The Pattern can be related to any type of event or object. If the set of numbers are related to each other in a specific rule, then the rule or manner is called a pattern. Sometimes, patterns are also known as a sequence.

According to question

7 12 10 15 13 .........

The pattern in the series is  

7+5 = 12

12-2 = 10

10+5=15

15-2= 13 .....................

Hence, the pattern is +5 then -2 alternatively .
