Step-by-step explanation:

y-y1=m(x-x1)

y-2=-3(x+1)

y-2=-3x-3

+2    +2

y=-3x-1

A ≈ 473.63

Step-by-step explanation: To find the surface area for a pyramid, we can use this formula: [tex]A=lw+l\sqrt{(\frac{w}{2})^2 } +h^2+w\sqrt{(\frac{l}{y} } )^2+h^2[/tex]

Solution: [tex]10\times10+10\times\sqrt{(\frac{10}{2} } )^2+18^2+10\times\sqrt{(\frac{10}{2} } )^2+18^2=423.63[/tex]

Answer:

you need to know what domain and range mean... so remember domain is the input.... range is the output..    :)

Step-by-step explanation:

the input .. "x"  in this case.. can be any number .. so the domain is all real numbers.

the output.. or range.. is limited.. b/c the square on the  'x" will always make that number positive.. and then it's multiplied by the negative 2.... so that term will always be negative.  : |  hmmmm so when is that squred term the smallest it can be?  hmmm  when it's zero... soooo this function will .. at it's greatest point be 3 and go down from there...

the range is from -∞  to 3  

see? :)

Answer:

27

Step-by-step explanation:

4 1/2  = 9/5

9/2 : 1/6  =

9/2 x 6/1 =

(9x6) / (2x1) =

54/2  = 27

Answer:

Divide through by  2  .

x2 - 2x - 3  =  0           What two numbers add to  -2  and multiply to  -3  ? →   +1   and   -3

                                  So...we can factor it like this...

(x + 1)(x - 3)  =  0        Set each factor equal to zero and solve for x.

x + 1  =  0          and          x - 3  =  0

x  =  -1               and          x  =  3

Answer:

Step-by-step explanation:

300×1.035⁵ ≅ $356.31

:::::

UPS charge = 7 + (p-1)0.20 = 0.20p +6.80

FedEx charge = 5 + (p-1)0.30 = 0.30p + 4.70

0.30p + 4.70 = 0.20p +6.80

0.10p = 2.1

p = 21

They charge the same for 21 pounds.

Answer:

1) Growth

2) y = 3

Explanation:

1) y = a*b^x

   y = 3 + 2^x

2 > 1, so it's growth

Answer:

(v/8)×8 = v    and  2×8=16 so:

v/8 = 2

v = 16

Answer:

v = 16

Step-by-step explanation:

8 x 2 = 16

16/8 = 2

so v =16

Answer: The interest rate was 9%.

Step-by-step explanation:

If principal amount P is invested at the rate of r percent with simple interest(I) for t years, the formula to find rate :

[tex]R=\dfrac{I\times100}{P\times t}[/tex]

As per given,

P = $ 500, I = $45, t = 1 year

Substitute values in formula , we get

[tex]R=\dfrac{45\times100}{500\times1}\\\\\Rightarrow R=9\%[/tex]

Hence,  The interest rate was 9%.

19.625cm squared because you have to divide the diameter by 2 to get the radius.

Area of circle = pi times radius times radius

= 3.14 times 2.5 times 2.5

= 19.625cm squared

Answer:

46.6°

Step-by-step explanation:

A slide at a children's park is 74 inches tall in the horizontal distance The slide covers is 70 inches what is the angle measures created by the slide and the ground

We solve the above question using Trigonometric function of Cosine.

tan x = Opposite/Adjacent

x = The angle

Hypotenuse = Slide covers = 70 inches

Adjacent = 74 inches

tan x = 74/70

x = arc tan (74/70)

x = 46.591140271°

Approximately = 46.6°

Answer:

9801

Step-by-step explanation:

The computation is shown below

Given that

81×121

Based on the above equation we simply solve this equation by multiplying them i.e.

= 81×121

= 9801

Hence, the answer is 9801

Answer:

The axis of symmetry is x=1

The vertex is (1,-9)

The x-intercepts are (4,0) and (-2,0)

The y-intercept is (0,-8)

Step-by-step explanation:

axis of symmetry is the line where the vertex is, so in the quadratic of x^2, the axis of symmetry would be zero because half of the equation is on one side and the other half on the other side

The vertex is the lowest point on the quadratic, on the y values

the x-intercepts are the places the graph intercepts the x-axis.

The y-intercepts are the places the graph intercepts the y-axis
