Answers

Answer 1

Answer:

16.75 cm

Step-by-step explanation:

Substitute into the formula.

x/2 π = 120/360

Solve.

x/2 π*8 = 120/360

x/16 π = 1/3

3x = 16 π

X = 16 π/3

X = 16*3.14/3

X = 16.746666666666666666666666666667

X = 16.75

Got it right on the test

how do i sketch a graph of y=2x that passes through the origin

Answers

Step-by-step explanation:

Given

Equation of line is [tex]y=2x[/tex]

Equation of line with slope m and intercept c on Y-axis is

[tex]y=mx+c[/tex]

Comparing the given line with slope-intercept form

[tex]\Rightarrow m=2\ \text{and}\ c=0[/tex]

The slope is also equal to [tex]\tan \theta[/tex]

[tex]\Rightarrow \tan \theta =2\\\Rightarrow \theta =63.43^{\circ}[/tex]

To sketch the equation of [tex]y=2x[/tex]

Make a line that passes through the origin at an angle of [tex]63.43^{\circ}[/tex] with the x-axis.

For which values of x will the rational expression below be undefined? Check
all that apply.
(x - 1)(x + 1)
X + 2
A. -1
B. 1
C. -2
D. 2
E. -5
F 5

Answers

Answer:

-2

Step-by-step explanation:

For the given expression to be undefined, this means that the denominator must be zero.

From the given expression, the denominator is x + 2

Equating this to zero;

x+2 = 0

Subtract 2 from both sides

x+2-2 = 0 -2

x = -2

Hence the value of x that makes it undefined is -2

A tree is broken at a height of 7m from the ground and its top touches the ground at distance of 24m from the base of the tree. Find the original height of the tree. pls help with steps

Answers

let the broken part of tree be x
then total height of tree=7+x
since it form a right angled triangle with base 24m and height 7m and hypotenuse be x
then by using Pythagoras theorem
(hypotenuse)^2=(base)^2+(height)^2
x^2=24^2+7^2
x^2=576+49
x^2=625
x=25
therefore height of tree =x+7=25+7=31

Answer:

x = 3

Step-by-step explanation:

The equation can be rewritten to make use of the graphing calculator's ability to identify function zeros:

x(x -2)(x +3) -18 = 0

The attached shows x = 3 is the only real solution.

_____

We're not sure what "system of equations" is intended. Perhaps it is ...

y = 18

y = x(x -2)(x +3)

To create the expression we graphed, we effectively subtracted the first equation from the second.

Answer:

Step-by-step explanation:

X° + 116° = 180°(sum of opposite angle of a quadrilateral in circle is equal 180 °)

x°=180-116

x°=64°

therefore

Answers

Answer:

Hope that helps!

Step-by-step explanation:

The expression that represents all clothing is being marked down 15%.

is A) 0.85x.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

We know fractions and percentages are related.

Assuming the cost of clothing to be 'x'.

∴ After the markdown of 15% it is,

= {(100 - 15)/100}×x.

= {85/100}×x.

= 0.85x
