A rectangular deck is 12 ft by 14 ft. When the length and width are increased by the same amount, the area becomes 288 sq . By h

julia-pushkina [17]

Well to get the area of 288 the dimensions would be a couple of things but 16 ft by 18 ft seems to work, so the dimensions increase by 4 ft on each side.

12+4=16
14+4=18

18*16=288

Alja [10]

Answer:

$x=134.05m$

Step-by-step explanation:

From the question we are told that:

Slant Height of Kite $h_s=175$

Angle $\theta=40 \textdegree$

Since Emma,The Kite and Andrew forms a right angle triangle

Generally the equation for distance between Andrew from Emma is mathematically given by

$x=h_scos\theta$

$x=175cos40$

$x=134.05m$

Maria invests $6,154 in a savings account with a fixed interest rate of 8% compounded continuously. What will the account balanc

Vitek1552 [10]

Answer:

$13,695.98

Step-by-step explanation:

We can use the continuous compound interest formula to solve:

$A = Pe^{rt}$

<em>P = principal amount</em>

<em>r = interest rate (decimal)</em>

<em>t = time (years)</em>

<em />

First, lets change 8% into a decimal:

8% -> $\frac{8}{100}$ -> 0.08

Now, lets plug in the values:

$A=6,154e^{0.08(10)}$

$A=13,695.98$

The account balance after 10 years will be $13,695.98

What is the point-slope form of a line with slope 3 that contains the point (2,1)

ryzh [129]

Answer:

Point slope form:

The equation of line is given by: $y-y_1=m(x-x_1)$ .....[1]

where m is the slope and a line contains a point $(x_1, y_1)$ .

As per the given statement:

Slope(m) = 3

$(x_1, y_1)$ . = (2, 1)

Substitute these in [1] we have;

$y-1=3(x-2)$

therefore, the point slope form of a line with slope 3 that contains the point (2, 1) is; $y-1=3(x-2)$

Y=f(x) = (1/2)<br> Find f(x) when x = 1

sammy [17]

The value of function on x=1 is 0.5

Step-by-step explanation:

In order to find the value of a function on given input, the input is put at the place of variable in the function.

Given function is:

$f(x) = (\frac{1}{2})^x$

We have to find the value of function on x = 1

Putting x = 1 in function

$f(1) = (\frac{1}{2})^1\\= \frac{1}{2}\\= 0.5$

Hence,

The value of function on x=1 is 0.5
