A cheetah can run up to 75 miles per hour how many yards per minute is this

Nataly [62]

75 miles per hour means,
75 miles per 60 minutes.
And this makes 1.25 miles per 1 minute.
1 mile is 1760 yards.
So 1.25 miles is ;
1.25 * 1760 = 2200 yards.
Answer is 2200 yards per minute.

Genrish500 [490]

Answer:

Step-by-step explanation:

in quadrant 1 cos and sec are positive.

cos(θ)=√(1-sin²θ)=√(1-(12/13)²)=√((169-144)/13²)=5/13

secθ=13/5

Solve one of the following two non-homogeneous differential equations using whatever technique your prefer. Put an "X" through t

noname [10]

Answer:

a. $y(x)=c_1e^{2x}+c-2xe^{2x}+x^3e^{2x}$

b $y(x)=c_1cos 3x+c_2 sin 3x-5 cos x+ 7sin x$

Step-by-step explanation:

1. $y''-4y'+4y=6x e^{2x}$

Auxillary equation

$D^2-4D+ 4=0$

$(D-2)(D-2)=0$

D=2,2

Then complementary solution = $C_1e^{2x}+C_2xe^{2x}$

Particular solution $=\frac{6 xe^{2x}}{(D-2)^2}$

D is replace by D+2 then we get

P.I= $\frac{6xe^{2x}}{0}$

P.I= $\frac{e^{ax}}{D+a} \cdot .V$

where V is a function of x

P.I= $\frac}x^3e^{2x}$

By integrating two times

Hence, the general solution

$y(x)=c_1e^{2x}+c-2xe^{2x}+x^3e^{2x}$

b.y''+9y=5 cos x-7 sin x

Auxillary equation

$D^2+9=0$

D= $\pm 3i$

$C.F=c_1 cos 3x+ c_2sin 3x$

P.I= $\frac{5 cos x-7 sin x}{D^2+9}$

P.I= $\frac{sin ax}{D^2+bD +C}$

Then D square is replace by -a square

$D^2$ is replace by - then we get

P.I=-5 cos x+7 sin x

The general solution

$y(x)=c_1cos 3x+c_2 sin 3x-5 cos x+ 7sin x$
