work out the value of angle x

Answers

Answer:

x = 45°

Step-by-step explanation:

the triangle has 2 congruent sides and is therefore isosceles with the base angles being congruent, both x

the sum of the 3 angles = 180° , then

x + x + 90° = 180° ( subtract 90° from both sides )

2x = 90° ( divide both sides by 2 )

Answers

Answer:

Number  = 15.

Step-by-step explanation:

Given : If you multiply a number by 3 and then subtract 5, you will get 40.

To find : what is the number.

Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.

According to question :

Let the number =  x

Multiply is with 3 = 3x

Subtract 5 from it we get 40 .

3x -5 = 40

On adding both sides by 5

3x = 45 .

On dividing both sides by 3

x =  15.

Therefore, Number  = 15.

Find the area of the figure above.
[?] square inches

Answers

Answer:

280 inches

Step-by-step explanation:

The area can be found by looking at each shape individually.

The area of the square can be found my multiplying the length by the width...
14*14 = 196 square inches

The area of the triangle can be found by multiplying the base by the height and dividing by 2...
A = b*h/2 (or some text books say half of the base times the height)

We knot the height of the triangle is 12 inches, and the base is implied as it shares a side with a square which has 4 equal sides of 14 inches.  Therefore
A = (14*12)/2 = 84 square inches

We get the total area by combining the two segments...
Area (triangle) + Area (square) = Area (total)
84 + 196 = 280 square inches

Lydia got her learners permit and helped her parents drive to her grandparent's house and back. It took one hour less time to get there than it did to get back. The average speed on the trip there was 60 km/hour. The average speed on the way back was 40 km/hour. How many hours did the trip there take?

Select the correct response:
2 hours
3 hours
5 hours
4 hours

Answers

Using the relation between velocity, distance and time, it is found that the trip took 2 hours.

What is the relation between velocity, distance and time?

Velocity is distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex]

On the first part of the trip, a time of t was taken, with an average speed of 60 km/hour, hence:

[tex]60 = \frac{d}{t}[/tex]

d = 60t

On the second part, a time of t + 1 was taken, with an average speed of 40 km/hour, hence:

[tex]40 = \frac{d}{t+1}[/tex]

d = 40(t + 1).

Since the distance is equal for both parts, we can equal the equations and find the time.

60t = 40t + 40

20t = 40

t = 2.

The trip took 2 hours.

The population of NBA players is Normally distributed

with a mean of 6'7" and a standard deviation of 3. 9

inches. (Wikipedia) Greg is considered unusually tall for

his high school at 6' 3".

1. About what percent of NBA players are taller than Greg?

2. About what percent are shorter?

3. What minimum height would Greg have to be (IN INCHES) in order to be in the top 2. 5% of

NBA player heights?

Answers

Using the normal distribution, it is found that:

1. 85% of NBA players are taller than Greg.

2. 15% are shorter.

3. A height of 6'11'' would be needed.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

In inches, considering that a feet has 12 inches, the mean is of [tex]\mu = 6 \times 12 + 7 = 79[/tex].The standard deviation is of [tex]\sigma = 3.9[/tex].Greg is 6'3'', that is, X = 6 x 12 + 3 = 75.

Item 1:

The proportion is one subtracted by the p-value of Z, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{75 - 79}{3.9}[/tex]

[tex]Z = -1.03[/tex]

[tex]Z = -1.03[/tex] has a p-value of 0.15

1 - 0.15 = 0.85.

85% of NBA players are taller than Greg.

Item 2:

100 - 85 = 15% are shorter.

Item 3:

This is X when Z has a p-value of 1 - 0.025 = 0.975, so X when Z = 1.96.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.96 = \frac{X - 75}{3.9}[/tex]

[tex]X - 75 = 1.96(3.9)[/tex]

[tex]X = 83[/tex]

83 = 6 x 12 + 11.

A height of 6'11'' would be needed.

What is the discriminant of a quadratic equation?

The value of a discriminant of a quadratic equation shows how many roots f(x) have. If the value of the discriminant is greater than 0 then the quadratic equation has real and distinct roots and if the value of the discriminant is equal to 0, then the quadratic equation has real and same roots. In case the value of the discriminant is less than zero then the quadratic equation will have no real roots.

In order to know if the quadratic equation has real roots or not, we need to find the discriminant of the given quadratic equations,

A.) [tex]-x^2+2x -6 = 0[/tex]

Here, a= -1, b=2 and c=-6

[tex]D = b^2 -4ac[/tex]

[tex]D = 4 -24\\D = -20[/tex]

As the value of the discriminant is negative it will not have real roots.

B.) [tex]-2x^2+3x+4 = 0[/tex]

Here, a= -2, b=3 and c=4

[tex]D = b^2 -4ac[/tex]

[tex]D = 9 +32\\D = 41[/tex]

As the value of the discriminant is positive it will have real roots.

C.) [tex]2x^2+x-6 = 0[/tex]

Here, a=2, b=1 and c=-6

[tex]D = b^2 -4ac[/tex]

[tex]D = 1 +48\\D =49[/tex]

As the value of the discriminant is positive it will have real roots.

A.) [tex]2x^2 -x+3 = 0[/tex]

Here, a=2, b=-1 and c=3

[tex]D = b^2 -4ac[/tex]

[tex]D = 1-24\\D = -23[/tex]

As the value of the discriminant is negative it will not have real roots.

Solution:

The least possible number of steps will be the lowest common multiples of these sets of steps.

We want fractions that will give whole numbers because realistically, one cannot take half a step of a step.

 So, the number of steps must be a multiple of denominators of the fractions given.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

A function is a fifth-degree polynomial.

Now,

Since, We know that;

The turning point of n degree polynomial = n - 1

Here, The highest power of the polynomial = 5

Thus, The turning point of 5 degree polynomial = 5 - 1

                                                                           = 4

Therefore, A function with a fifth-degree polynomial have 4 turning points.
