Answer:

12 meters

Step-by-step explanation:

We can solve this problem simply by dividing area by the known width value (because length x width = area):

96/8 = 12

Answer:  [tex]X+Y=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex]

Step-by-step explanation:

Given:  [tex]X=\begin{pmatrix}3&-5\\ -4&2\end{pmatrix},\ \ Y=\begin{pmatrix}6&7\\ -4&-3\end{pmatrix}[/tex]

To calculate: [tex]X+Y[/tex]

Consider [tex]X+Y= \begin{pmatrix}3&-5\\ -4&2\end{pmatrix}+\begin{pmatrix}6&7\\ -4&-3\end{pmatrix}[/tex]

[tex]=\begin{pmatrix}3+6&\left(-5\right)+7\\ \left(-4\right)+\left(-4\right)&2+\left(-3\right)\end{pmatrix}\\\\=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex][[tex]\mathrm{Add\:the\:corresponding\: elements\: and\: simplify}[/tex]]

Hence, [tex]X+Y=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex]

Answer:

  3π units

Step-by-step explanation:

The full circumference of a circle with radius 2 is ...

  C = 2πr

  C = 2π(2) = 4π

The arc shown is 3/4 of the full circle circumference so is ...

  3/4C = (3/4)(4π) = 3π . . . units

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

OVERALL Answer: x > -1; It is an OPENED circle shaded to the right starting at -1 (Option A.)

Good luck on your assignment and enjoy your day!

The Answer is B 5 is the height

Answer:  55

Reason: Corresponding Angles Theorem

The 55 degree angle up top, and angle 1 are the same measure, because they are corresponding angles. This only works when we have parallel lines like this.

Answer:

Step-by-step explanation:

using formula

=

=3[tex]\sqrt{3}[/tex]/2*6^2

=108[tex]\sqrt{3}[/tex]/2

=54[tex]\sqrt{3}[/tex]

=93.5

Answer:

The hypotenuse is 10 cm long.

Step-by-step explanation:

We can find the hypotenuse by using the following formula where "c" is the length of the hypotenuse and "a" and "b" are the lengths of the legs.

[tex]c = \sqrt{a^{2} + b^{2} }[/tex]

Now we just substitute the values and get...

[tex]c = \sqrt{a^{2} + b^{2} }\\c = \sqrt{6^{2} + 8^{2} } \\c = \sqrt{36 + 64} \\c = \sqrt{100} \\c = 10[/tex]

Therefore the hypotenuse is 10 cm long.

Answer:

y = 2x - 8

Step-by-step explanation:

y = 2x + b

-2 = 2(3) + b

-2 = 6 + b

-8 = b

Answer:

{ x | -3 <= x < +1 }

Step-by-step explanation:

We note that the graph occupies from x=-3 to x=+1, while -3 is a value included (endpoint is solid), and +1 is excluded (endpoint hollow).

Thus the domain is { x | -3 <= x < +1 }

Answer:

The original price was $16

Step-by-step explanation:

$4= 25% of What price?

4= .25 x W

Divide both sides by .25

This leaves the equation as 16=W

Answer:

{-1, 10}

Step-by-step explanation:

Next time please share the entire set of instrutions.

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:

Just as the square root is a number that, when squared, gives the radicand, the cube root is a number that, when cubed, gives the radicand. Cubing a number is the same as taking it to the third power: 23 is 2 cubed, so the cube root of 23 is 2.

Step-by-step explanation:

there i hope you understood

The graphs of Square root function only continues in one direction forever whereas the cube root function continues in two directions forever.

"The principal square root function [tex]f(x) = \sqrt{x}[/tex] (usually just referred to as the "square root function") is a function that maps the set of non negative real numbers onto itself."

"The cube root function [tex]f(x) = \sqrt[3]{x}[/tex]  is a continuous function, with no start or end point. Its domain is all real numbers."

The similarities  in the graphs of square root function and cube root function are positive function (0,∞), x-intercept: intersects x-axis at (0, 0)

y-intercept: intersects y-axis at (0, 0).

The square root function only utilizes the positive square root. If both positive and negative square root values were used, it would not be a function. The cube root function can process  both positive and negative values.

Hence, the graphs of Square root function only continues in one direction forever whereas the cube root function continues in two directions forever.
