The 3 angles when added together need to equal 170.

To find the 3rd angle subtract the 2 given angles from 180

180-30-70 = 80

Answer: B. 80

Answer:

B) 80

Step-by-step explanation:

All triangles add up to 180 degrees

So to solve angle 3 the equation would be

Angle 3 = 180 - Angle 1 - Angle 2

Angle 3 = 180 - 30 - 70

Angle 3 = 80

4 1/100

Step-by-step explanation:

Answer:

4 1/100

Step-by-step explanation:

Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are  2   numbers to the right of the decimal point, place the decimal number over  10 ^2  ( 100 ) . Next, add the whole number to the left of the decimal.

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

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.

Step-by-step explanation:

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.

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]

In this problem:

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.

The quadratic equations that have real roots are [tex]-2x^2+3x+4 = 0[/tex] and  [tex]2x^2+x-6 = 0[/tex].

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.

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

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

What is mean by Subtraction?

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.

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 )
