Order the lengths of the sides of triangle ABC from greatest to least Angle A = 78° angle B = 56° and angle C = 46°

Answer:

AB = 3π units

Step-by-step explanation:

The arc length is calculated as

AB = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{45}{360}[/tex]

     = 2π × 12 × [tex]\frac{1}{8}[/tex]

     = 24π × [tex]\frac{1}{8}[/tex]

     = 3π units

x^2 - 9x - 15 = -5 should be rewritten in standard quadratic form:

x^2 - 9x - 10 = 0 = (x - 10)(x + 1) = 0.

Setting each factor equal to zero and then solving for x yields {-1, 10}

Answer:

{-1,10}

Step-by-step explanation:

[tex]x^2-9x-15=-5[/tex]   given

[tex]x^2-9x-10=0[/tex]   addition property of equality

[tex]x^2+(x-10x)-10=x^2+x-10x-10=0[/tex]   x-10x = -9x

[tex]x(x+1)-10(x+1)=0[/tex]   distributive property ( x( y + z ) = xy + xz

[tex](x-10)(x+1)=0[/tex]   distributive property (backwards)

[tex]x-10=0;x=10;x+1=0;x=-1[/tex]   at least one factor of 0 has to be 0

{-1,10}

Answer:

[tex]d(P,Q) = \sqrt{34}[/tex]

The midpoint of the segment is M(27.5, -13.5).

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between P(25,-15) and Q​(30,-12)

[tex]d(P,Q) = \sqrt{(30-25)^2+(-12-(-15))^2} = \sqrt{34}[/tex]

So

[tex]d(P,Q) = \sqrt{34}[/tex]

Coordinates of the midpoint M of the segment PQ.

Mean of the coordinates of P and Q. So

[tex]x_M = \frac{25+30}{2} = \frac{55}{2} = 27.5[/tex]

[tex]y_M = \frac{-15-12}{2} = -\frac{27}{2} = -13.5[/tex]

The midpoint of the segment is M(27.5, -13.5).

Hey there!

-2<3x+1

= 3x + 1 < -2

SUBTRACT 1 to BOTH SIDES

3x + 1 - 1 < -2 + 1

CANCEL out: 1 - 1 because that gives you 0

KEEP: -2 + 1 because that helps you solve for x

-2 + 1 = -3

New EQUATION: 3x > -3

DIVIDE 3 to BOTH SIDES

3x/3 > -3/3

CANCEL out: 3/3 because that gives you 1

KEE3 -3/3 because that helps us compare for x

-3/3 = -1

Answer to the equation: x > -1

Step-by-step explanation:

V = Bh   where B is the area of the base (triangle) and h is the height of prism

B = bh/2 = 8(8)/2 = 64/2 = 32

height of prism = 10

V = 32(10) = 320 cu. yd.

Answer:

The correct option is - D.

Step-by-step explanation:

To find - Select the correct answer. The parent tangent function is transformed such that its period is halved. Which graph could represent the transformed function?

Solution -

We know that,

The parent tangent function is -

f(x) = tan(x)

Period of Parent function = [tex]\pi[/tex]

Now,

If Period is half,

Then

The function is transformed to

f(x) = tan(2x)

So,

The graph becomes

Step-by-step explanation:

The interquartile range of the given list is 11 oz.

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

To find the interquartile range (IQR), we first need to find the first quartile (Q1) and the third quartile (Q3) of the data.

To do this, we first need to order the data set from smallest to largest:

8 oz, 8 oz, 12 oz, 16 oz, 16 oz, 18 oz, 20 oz, 20 oz

Next, we find the median of the data set. Since there are 8 data points, the median is the average of the two middle values:

Median = (16 oz + 16 oz)/2 = 16 oz

Now we can find Q1 and Q3. Q1 is the median of the lower half of the data set, and Q3 is the median of the upper half of the data set.

Lower half: 8 oz, 8 oz, 12 oz, 16 oz

Upper half: 16 oz, 18 oz, 20 oz, 20 oz

Q1 = (8 oz + 8 oz)/2 = 8 oz

Q3 = (18 oz + 20 oz)/2 = 19 oz

Finally, we can calculate the IQR as the difference between Q3 and Q1:

IQR = Q3 - Q1 = 19 oz - 8 oz = 11 oz

Therefore,

The interquartile range of the given list is 11 oz.
