Answer:

(a) The complete table

\begin{array}{cccccc}Hours & {1} & {2} & {3} & {4}  &{5}\ \\ {Amount} & {\$9.50} & {\$19.00} & {\$28.50} & {\$38.00} & {\$47.50} \ \end{array}

(b) $38.00

(c) 3 hours

Step-by-step explanation:

Given

Earnings = \$9.50 per hour

See attachment for complete question;

Solving (a): Complete the table

To complete the table, we simply multiply the earnings by the number of hours.

So, we have:

Hours = 2 \to Earnings = \$9.50 * 2 = \$19.00

Hours = 3 \to Earnings = \$9.50 * 3 = \$28.50

Hours = 4 \to Earnings = \$9.50 * 4 = \$38.00

Hours = 5 \to Earnings = \$9.50 * 5 = \$47.50

Solving (b): Earnings, if Megan works for 4 hours

In (a) above, we have:

Hours = 4 \to Earnings = \$9.50 * 4 = \$38.00

This implies that Megan will earn $38.00

Solving (c): Hours to earn $28.50

In (a) above, we have:

Hours = 3 \to Earnings = \$9.50 * 3 = \$28.50

This implies that Megan will work for 3 hours to earn $28.50

Find surface area please
MArishka [77]

Answer:

203

Step-by-step explanation:

When calculating surface area, you add the area of each side.

Base: LxW = 7x7 = 49

Triangle Sides: 1/2 b x h = 1/2(7) x 11 = 38.5

4 sides: 38.5x4 = 154

154+49 = 203

Consider the parabola r​(t)equalsleft angle at squared plus 1 comma t right angle​, for minusinfinityless thantless thaninfinity
kodGreya [7K]

Given:-   r(t)=< at^2+1,t>  ; -\infty < t< \infty , where a is any positive real number.

Consider the helix parabolic equation :  

                                              r(t)=< at^2+1,t>

now, take the derivatives we get;

                                            r{}'(t)=

As, we know that two vectors are orthogonal if their dot product is zero.

Here,  r(t) and r{}'(t)  are orthogonal i.e,   r\cdot r{}'=0

Therefore, we have ,

                                  < at^2+1,t>\cdot < 2at,1>=0

< at^2+1,t>\cdot < 2at,1>=

                                              =2a^2t^3+2at+t

2a^2t^3+2at+t=0

take t common in above equation we get,

t\cdot \left (2a^2t^2+2a+1\right )=0

⇒t=0 or 2a^2t^2+2a+1=0

To find the solution for t;

take 2a^2t^2+2a+1=0

The numberD = b^2 -4ac determined from the coefficients of the equation ax^2 + bx + c = 0.

The determinant D=0-4(2a^2)(2a+1)=-8a^2\cdot(2a+1)

Since, for any positive value of a determinant is negative.

Therefore, there is no solution.

The only solution, we have t=0.

Hence, we have only one points on the parabola  r(t)=< at^2+1,t> i.e <1,0>

Can anyone help me understand how to evaluate the limit of this complex fraction?
SSSSS [86.1K]

Answer:

-1/9

Step-by-step explanation:

\lim_{x \to 3} \frac{1/x-1/3}{x-3}

For simplicity, let's multiply top and bottom by 3x:

\lim_{x \to 3} \frac{3-x}{3x(x-3)}

Factor out a -1:

\lim_{x \to 3} \frac{-(x-3)}{3x(x-3)}

Divide top and bottom by x−3:

\lim_{x \to 3} \frac{-1}{3x}

Evaluate the limit:

\frac{-1}{3(3)}\\-\frac{1}{9}

It's important to note that the function doesn't exist at x = 3.  As x <em>approaches</em> 3, the function <em>approaches</em> -1/9.
