Answer:

a = 7

b = 7[tex]\sqrt{2}[/tex]

Step-by-step explanation:

in a 45-45-90° triangle, the length of legs to hypotenuse is 1 : [tex]\sqrt{2}[/tex]

Answer:

m<C  = 36.87degrees

Step-by-step explanation:

Solve for the approximate measure of angle C.

From the given diagram;

AC is the hypotenuse

BC is adjacent to <C

Cos m<C = adj/hyp

Cos m<C = BC/AC

Cos m<C = 20/25

Cos m<C = 0.8

m<C = arccos (0.8)

m<C  = 36.87degrees

Answer:

Step-by-step explanation:

r=4 in

h=15 in

The paint can is a cylinder. The volume of the cylinder is: V=S×h (S stands for the area of the base, h is for height).

The area of our cylinder's base is a circle, so:

S=πr²=4²×π=16π≈50.24 (in²)

Thus, the volume is:

V≈50.24×15≈753.6 (in³)

Answer:

the center of the data set is 7 so probably 7

7 is the best representation of the center of given data set.

The correct answer is an option (C).

"It is the average of the given numbers."

"I is the middle value of a sorted list of numbers."

For given question,

We have been given a dot plot of the number of letters in each students first name.

From the given dot plot,

We have data as 3, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6,6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10, 10, 11, 11, 11

From above data,

the total number of students in the class are n = 30

We write 3, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6,6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10, 10, 11, 11, 11 as 3, (4 × 2), (5 × 4), (6 × 7), (7 × 7), (8 × 3), 9, (10 × 2), (11 × 3)

So, the mean of the above data would be,

[tex]\Rightarrow \bar{X}=\frac{3+ (4\times 2)+(5\times 4)+(6\times 7)+(7\times 7)+(8\times 3)+9+(10\times 2)+(11\times 3)}{30}\\\\\Rightarrow \bar{X}=\frac{208}{30}\\\\\Rightarrow \bar{X}=6.93\\\\\Rightarrow \bar{X}\approx 7[/tex]

From above data we can observe that there are two numbers in middle of the data 6 and 7.

So, the median would be,

[tex]\Rightarrow M=\frac{6+7}{2}\\\\\Rightarrow M=6.5\\\\\Rightarrow M\approx 7[/tex]

Therefore, 7 is the best representation of the center of given data set.

The correct answer is an option (C).

Answer:

  A

Step-by-step explanation:

The axis of symmetry of quadratic ax²+bx+c is x=-b/(2a). For the given equation, the axis of symmetry is ...

  x = -4/(2(3/2)) = -4/3

The only graph with its vertex at x=-4/3 is graph A.

_____

Additional comment

You can also make the correct choice by evaluating the equation at a couple of different values of x. Convenient ones are x= -1, or 0, or +1. The value at x=0 is the y-intercept, (0, -2), which seems to be a point on all of the graphs. The value at x=1 is 3/2+4-2 = 3.5, which looks like it is only seen on graph A.

Answer:

Total 17 high rate filters are required

Step-by-step explanation:

Given -

Rate of filtration of slow sand filters = 10 million gallons/acre-day

Total million gallons of water filtered per day = 10 million gallons/acre-day * 15 acres

= 150 Million gallons per day

Rate of filtration of high rate filters = 6 gpm/ft2

Area of one high rate filter = 1,000 ft2

Volume of water filtered by 1 high rate filter is 6 gpm/ft2 *1,000 ft2 = 6000 gallons per minute  = 8640000 gallon per day

Number of filters required = 150 million gallons per day /8640000 gallon per day

150 * 10^6/8640000

17

Total 17 high rate filters are required

Part A: Explain to Professor M how you will solve the pair of equations by using either substitution or elimination. Show all the steps you use and write the solution in (x, y) form.

Part B: If she asked you to graph the two equations, at what point will the lines representing the two equations intersect? Explain how you know this.

Answer:

Length: 7y^2+3

Width: 10y^6

Step-by-step explanation:

Given that the rectangle has an area of 70y^8 + 30y^6.

The width of the rectangle is equal to the greatest common monomial factor of 70y^8 and 30y^6.

First let us get the width;

70y^8 = 7 * 10 * y^2 * y^6

30y^6 = 3 * 10 * y^6

Since 10y^6 is common to both factors, hence the width of the rectangle will be 10y^6

Given;

Area = Length * width

A(x) = W(x)*L(x)

A(x) = 70y^8 + 30y^6

A(x) =  10y^6(7y^2+3)

On comparison

L(x) = 7y^2+3

Hence length is 7y^2+3 and width is 10y^6

Answer:

48.56 cm

Step-by-step explanation:

The rectangle: 10+10+8+8

= 36cm

The half circle: 1/2 πd

=1/2x3.14X8

= 12.56

So, the total perimeter will be- 36+12.56

=48.56

Answer:

40.565cm

Step-by-step explanation:

To find a circumference (perimeter) of a cirlce, you need to use the formula C=2πr.

We know the diameter is 8 but we need the radius, the radius we would divide the diameter in half.

8 ÷ 2 = 4

Now that we know the radius is 4, you plug in 4 for r, and then solve

C= 2π4

C= 25.13

The circumference of the whole circle is 25.13 so we would cut it in half to get the half of the circle we need. So 25.13 ÷ 2 = 12.565.

Now that we have the circumference of the half-circle, it a lot easier. Take the 3 other sides and the half-circle and just add the together

8 + 10 + 10 + 12.565 = 40.565

Answer:

4

Step-by-step explanation:

The easiest way to solve this is just to put it in your calculator.  

But if you want to go deeper, then ln(x)^4 = 4*ln(x)

Since x in this case = e then ln (e)^1 = 1.

ln(e)^4 = 4*ln(e) = 4
