On a partly cloudy day, Derek decides to walk back from work. When it is sunny, he walks at a speed of s miles/hr (s is an integ

Setler [38]

Answer: $\frac{1}{7}$

Step-by-step explanation:

Given

sunny day speed= s mph

Rainy day speed=s+1 mph

Derek average speed =2.8 miles/hr

s<2.8<s+1

so on sunny day speed must be 2 mph

and on rainy day speed must be 3 mph

$v_{avg}=\frac{distance}{time\ taken}$

Let x be the distance traveled in sunny and y be the distance traveled in rainy weather

$2.8=\frac{x+y}{\frac}{x}{2}+\frac{y}{3}}$

Let $\frac{x}{y}=z$

$2.8=\frac{z+1}{\frac{z}{2}+\frac{1}{3}}$

$z=\frac{1}{6}$

Fraction of distance traveled on sunny weather

$\frac{x}{x+y}=\frac{z}{z+1}=\frac{1}{7}$

HELP ME PLS!!!!!!!!!!!!!!!!!!!

Advocard [28]

the number inside the parenthesis includes the interest rate ( annual percentage

looking at the possible functions, if you raise the interest rate to the power of 12, you would need to divide the number of years (t) by 12 as well

so the function could be rewritten as A=1000(1.023^12)^t/12

since the annual percentage rate is 2.3% ( 0.023)

divide 0.023/12*100 = 0.19% per month interest

The slope of the line is -2.

Solution:

Given points are (-3, -7) and (2, -17).

Here $x_1=-3, y_1=-7, x_2=2, y_2=-17$

Slope of the line:

$$m=\frac{y_2-y_1}{x_2-x_1}$

$$m=\frac{-17-(-7)}{2-(-3)}$

$$m=\frac{-17+7}{2+3}$

$$m=\frac{-10}{5}$

m = -2

The slope of the line that passes through the pair of points is -2.

Prove the following identities.<br> cos(3pi/s+x)=sinx

kari74 [83]

$\cos \left(\frac{3\pi}{2}-x \right)=\sin x \\ \\ =\cos \left(\frac{3\pi}{2} \right)\cos x -\sin \left(\frac{3\pi}{2} \right) \sin x \\ \\ =0\cos x -(-1)(\sin x) \\ \\ =\sin x$
