Can someone plzz help me
never [62]

For this case we have that by definition of trigonometric relations of a rectangular triangle that, the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle.

That is to say:

Sin (30) = \frac {IR} {14}

We clear the length of the leg:

IR = 14 * sin (30)\\IR = 14 * \frac {1} {2}\\IR = 7 \ in

Answer:

IR = 7 \ in

The perimeter of a rectangular garden is 42 feet. The length of the garden is 5 feet more than twice the width. Find the length
zlopas [31]

Answer:

W=5.3, l= 15.6

Step-by-step explanation:

Perimeter of a rectangle p=2(l+w)

P= 42

W= x

L= 5+2x therefore 42=2(5+2x+x)

42=10+6x , 32=6x

Make x subject of formula

X=32/6 x=5.3 there for w=5.3

Where L= 5+2x ; L=5+2(5.3)

L therefore = 15.6

Given the function g(x)= -x^2 + x + 5, determine the average rate of change of the function over the interval -4 ≤ x ≤ 3.​
OleMash [197]

Answer:

The average rate of change is 2.

Step-by-step explanation:

We are given the function:

g(x)=-x^2+x+5

And we want to find the average rate of change over the interval:

-4\leq x\leq 3

The average rate of change is synonymous with the slope. So, we will evaluate the function at its endpoints and find the slope between them.

Our first endpoint is given by:

g(-4)=-(-4)^2+(-4)+5=-15

And our second endpoint is given by:

g(3)=-(3)^2+(3)+5=-1

This gives us two points (-4, -15) and (3, -1). The average rate of change will be the slope between them. Thus:

\displaystyle ARC=\frac{-1-(-15)}{3-(-4)}=\frac{14}{7}=2

The average rate of change is 2.
