Answer:

-0.7073ft/sec

Step-by-step explanation:

Given the following

Distance covered by Ben = -29feet

Time taken = 41secs

Required

average change in depth each second(speed)

average change in depth each second = Distance/Time

average change in depth each second = -29/41

average change in depth each second = -0.7073ft/sec

Answer:

The answer is -29 divided by 41

Answer:

b=570

Step-by-step explanation:

5(590-b)=100

multiplying 5 with right hand side

2950-5b=100

2950-100=5b

2850=5b

2850/5=b

570=b

The value of x in the figure is 21.4

To do this, we make use of the following law of sine

[tex]\frac{\sin (A)}{a} = \frac{\sin (B)}{b}[/tex]

Using the values in the question, we have:

[tex]\frac{\sin (x)}{12} = \frac{\sin (42)}{22}[/tex]

Multiply both sides by 12

[tex]\sin (x) = \frac{12\sin (42)}{22}[/tex]

Evaluate the quotient

[tex]\sin (x) = 0.3650[/tex]

Take the arc sine of both sides

x = 21.4

Hence, the value of x is 21.4

Answer:

90 [tex]cm^{2}[/tex] of blue paint

Step-by-step explanation:

From the given diagram, the sides have the same dimensions and the shape of a triangle.

Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height

Given that, the base of each side = 6 cm, and the height = 10 cm.

Then,

Area of each side of the shape = [tex]\frac{1}{2}[/tex] x 6 x 10

                                              = 30 [tex]cm^{2}[/tex]

Since Leonard wish to paint only the 3 sides and not the bottom part of the shape, the amount of paint required can be determined as;

3 x area of each side = 3 x 30

                                   = 90 [tex]cm^{2}[/tex]

Leonard would need 90 [tex]cm^{2}[/tex] of paint to paint the sides of the shape.

Answer:

I. Length, L = 11 cm

II. Width, W = 6 cm

Step-by-step explanation:

Let the length of the rectangle be L.

Let the width of the rectangle be W.

Given the following data;

Area of rectangle = 66 cm²

Translating the word problem into an algebraic expression, we have;

L = 2W - 1 .....equation 1

We know that the area of a rectangle is given by the formula;

A = L * W

Substituting

66 = L * W ....equation 2

Substituting eqn 1 into eqn 2, we have;

66 = (2W - 1) * W

66 = 2W² - W

2W² - W - 66 = 0

Note: the standard form of a quadratic equation is ax² + bx + c = 0

a = 2, b = -1 and c = -66

Solving the quadratic equation using the quadratic formula;

The quadratic equation formula is;

[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]

Substituting into the equation, we have;

[tex] x = \frac {-(-1) \; \pm \sqrt {1^{2} - 4*2*(-66)}}{2*2} [/tex]

[tex] x = \frac {1 \pm \sqrt {1 - (-528)}}{4} [/tex]

[tex] x = \frac {1 \pm \sqrt {1 + 528}}{4} [/tex]

[tex] x = \frac {1 \pm \sqrt {529}}{4} [/tex]

[tex] x = \frac {1 \pm 23}{4} [/tex]

[tex] x_{1} = \frac {1 + 23}{4} [/tex]

[tex] x_{1} = \frac {24}{4} [/tex]

x1 = 6

We do not need the negative value of x, so we proceed.

Therefore, Width, W = x1 = 6 cm

Next, we find the length L;

From eqn 1;

L = 2W - 1

L = 2(6) - 1

L = 12 - 1

L = 11 cm

Using the density concept, it is found that the mass would stay the same, and the correct option is given by B.

B) A dot plot would show 7 points for numbers greater than 2.

D) A histogram would have a maximum of 7 bars.

Step-by-step explanation:

quiz on edg told me ;)

The true statements are:

B. dot plot would show 7 points for numbers greater than 2.

D. histogram would have a maximum of 7 bars.

A dot plot uses dots to show each data point, while for histogram, the frequency for the data values are depicted by bars or bins.

In the data ste given, 7 of the data points are greater than 2. So, the dot plot for the data distribution would display 7 points for values greater than 2.

Also, there are 7 different values, which are from 0 - 6. This will require 7 bars if we want to represent the data on a histogram.

Therefore, the true statements are:

B. dot plot would show 7 points for numbers greater than 2.

D. histogram would have a maximum of 7 bars.

The quadratic function [tex]f(x)[/tex] has one zero at [tex]x=-5[/tex] and a turning point at [tex](3,10)[/tex]. The value of other zero is [tex]11[/tex].

The Quadratic function [tex]f(x)[/tex] is a polynomial function with one or more variables in which the highest power of the variable is two. i.e.  [tex]f(x) = ax^{2} + bx + c[/tex]

The zeros of a polynomial [tex]f(x)[/tex] are all the [tex]x[/tex]-values that make the polynomial equals to zero. i.e. [tex]f(x)=0[/tex]

A turning point is a point at which the derivative changes sign.

We have,

One zero is  [tex](-5)[/tex],

Let other Zero be [tex]"a"[/tex],

Turning point at [tex](3,10)[/tex].

i.e. [tex]x=3[/tex] and [tex]y=10[/tex]

Since the difference between [tex]3[/tex] and [tex](-5)[/tex] is [tex]8[/tex].

So,

The difference between the other zero from [tex]3[/tex] should be the same as the difference between [tex]3[/tex] and [tex](-5)[/tex].

i.e.

[tex]a-3=8[/tex]

[tex]a=11[/tex]

Answer:

30cm

Step-by-step explanation:

Because of the polygon similarity postulate (PSP) 8/12=20/x

8/12=20/x

20/(8/12)=x

20*12/8=x

x=30 cm

The length of side x is 30 cm when the shapes below are mathematically similar.

To calculate the length of side x, we can use the concept of similarity between the shapes. When two shapes are mathematically similar, their corresponding sides are proportional.

8 cm corresponds to 20 cm

12 cm corresponds to x (unknown)

Using the concept of proportionality, we can set up the following equation:

(8 cm) / (20 cm) = (12 cm) / (x)

To find x, we can solve this equation:

Cross-multiplying:

8 cm * x = 20 cm * 12 cm

Simplifying:

8x = 240 cm²

Dividing both sides by 8 to isolate x:

x = 240 cm²/ 8

x = 30 cm

Therefore, the length of side x is 30 cm.

Answer:

x^2 - 6x -18  is the same so you can write

x^2 - 6x -18   = ( x^2 - 8x - 15 = 3)

Step-by-step explanation:

When we subtract 3 each side we get -18  as -15 -3  is -18

x^2 - 6x -15 = 3

x^2 - 6x -15- 3 =  

x^2 - 6x - 18 = 0

When equations equal or set equal to zero we can then use the quadratic formula found in your book.

x1  

= −(−8) − √ (−8)2 − 4×1×(−18)  /  2×1

= 8 − 2 × √ 34
