kvv77 [185]

Answer: 2.05 pints

Step-by-step explanation:

Shiva used 8.2 pints in total to paint the bedroom.

3/4 of this was blue paint which means that the remaining 1/4 is white paint.

Pints of white paint used:

= Proportion of white paint * Total pints used

= 1/4 * 8.2

= 2.05 pints

1. Draw the graph of f(x) = cos x for 0 I know how to construct the graph but I don’t know how to get the figures. Please help

KengaRu [80]

Answer:

Please refer to the attached figure.

Step-by-step explanation:

Given the function:

$f(x) =cosx \ where\ \{0^\circ\leq x\leq 360^\circ\}$

OR, the given function can also be written as:

$y = f(x) = cosx$

We know that graph of cosine is a wave.

and the range of cosine function is [-1, 1]

First of all, let us have a table of values at major values of x.

$x = 0, f(x) = 1\\x = 90, f(x) = 0\\x = 180, f(x) = -1\\x = 270, f(x) = 0\\x = 360, f(x) = 1$

So, the table of values for f(x) is:

$\begin{center}\begin{tabular}{ c c }x & cosx \\0 & 1 \\90 & 0\\180 & -1\\270 & 0\\360 & 1\\\end{tabular}\end{center}$

Let us mark these points on the xy coordinate axis where x axis represents value of x and y axis represents value of $f(x) = cosx$ and then join the points using a wave.

Please refer to the attached graph for the answer image.

.If x2 + kx+ 6 = (x + 2) (x + 3) for all x, then the value of k is

Verdich [7]

Answer:

k = 5

Step-by-step explanation:

$(x + 2)(x + 3) = {x}^{2} + 5x + 6$

Now comparing left hand side & right hand side ,

${x}^{2} + kx + 6 = {x}^{2} + 5x + 6$

Cancelling x^2 & 6 from both left hand side & right hand side ,

kx = 5x

=> k = 5
