Step-by-step explanation:

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]

Answer:

  C:  2x+2y=-2

Step-by-step explanation:

The equation that makes the system have infinitely many solutions is one that is dependent on the given equation. The easiest way to make a dependent equation is to multiply the given equation by some constant.

Here, choice C has the original equation multiplied by 2, so it is dependent on the given equation.

  x + y = -1   ⇒   2(x + y) = 2(-1)   ⇒   2x + 2y = -2 . . . . matches choice C

Answer:

Y = -1/2x+4

Step-by-step explanation:

The Y intercept is 4, so that's where the +4 comes in.

The slope is rise over run, so you count how many up you go from a whole number, in this case one, and that goes on top. Then you count how many it goes over, in this case two, and that goes on the bottom. The negative comes from which way the slope is going; down or up.

Answer:

Y = -1/2x+4

Step-by-step explanation:

The Y intercept is 4, so that's where the +4 comes in.

The slope is rise over run, so you count how many up you go from a whole number, in this case one, and that goes on top. Then you count how many it goes over, in this case two, and that goes on the bottom. The negative comes from which way the slope is going; down or up.

Answer:

yey

Step-by-step explanation:

Answer:

A)

1) 0.03072 = 3.072% probability you get the third head on the 5th toss.

2) The expected number of heads you will get when you toss the coin six times is 1.2.

B)

1) 0.2304 = 23.04% probability that you will get 2 heads and 3 tails.

2) The expected number of heads you will get when you toss the coin six times is 3.6.

Step-by-step explanation:

For each coin, there are only two possible outcomes. Either it is tails, or it is heads. The probability of a toss being heads or tails is independent of any other toss. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The expected value of the binomial distribution is E(X) = np.

Item A:

1) you get the third head on the 5th toss?

1/5 probability of heads, so [tex]p = \frac{1}{5} = 0.2[/tex]

This is two heads on 4 tosses(P(X = 2) when n = 4) and then head on the 5th toss, with 0.2 probability. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{4,2}.(0.2)^{2}.(0.8)^{2} = 0.1536[/tex]

0.1536*0.2 = 0.03072

0.03072 = 3.072% probability you get the third head on the 5th toss.

2) that you get the expected number of heads you will get when you toss the coin six times?

Six tosses means that [tex]n = 6[/tex]. So

[tex]E(X) = np = 6*0.2 = 1.2[/tex]

The expected number of heads you will get when you toss the coin six times is 1.2.

Question B:

3/5 probability of heads, which means that [tex]p = \frac{3}{5} = 0.6[/tex]

1) If you toss the coin 5 times, what is the probability that you will get 2heads and 3 tails?

This is P(X = 2) when n = 5. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{5,2}.(0.6)^{2}.(0.4)^{3} = 0.2304[/tex]

0.2304 = 23.04% probability that you will get 2 heads and 3 tails.

2) What is the expected number of heads you will get when you toss the coin six times?

Six times means that [tex]n = 6[/tex]. So

[tex]E(X) = np = 6(0.6) = 3.6[/tex]

The expected number of heads you will get when you toss the coin six times is 3.6.

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

(-∞,0)

Step-by-step explanation:

The graph of ƒ(x) = |x| is below.

The function is decreasing  on (-∞,0) .

A is wrong. The function both decreases and increases on (-∞,∞).

C is wrong. The function is decreasing on (-6,0), but that is only a portion of the interval.

D is wrong. the function is increasing on (o,∞)

Answer:

X value de correct answer

Based on the graph of the given limit of a function, the value for which [tex]\lim_{x \to a} g(x)[/tex] doesn't exist is equal to -3.

A limit can be defined as a numerical value which a function approaches (output) as the input value approaches other values. In Mathematics, limits are typically used to determine the following:

For the right-hand limit, we have:

[tex]\lim_{x \to -3^{+}}[ -3 + 1] = -2[/tex]

For the right-hand limit, we have:

[tex]\lim_{x \to -3^{-}} [-3 - 1] = -4[/tex]

By critically observing the graph of the given limit of a function, we can logically deduce that -3 is the value for which [tex]\lim_{x \to a} g(x)[/tex] doesn't exist because the right-hand limit and left-hand limit are not the same (different).

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:

108.75km

Step-by-step explanation:

please find attached the diagram

total displacement can be determined by using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

length of x =

20² + 40²

= 400 + 1600

2000

square root of 2000

= 44.72km

length of y

40² + 50²

1600 + 2500 = 4100

square root of 4100

64.03km

total displacement = 44.72 + 64.03 = 108.75

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:
