11th grade geometry:

Aliun [14]

Answer:

The perimeter is 72 units and the area is 149 square units.

Step-by-step explanation:

$\triangle SBA$ has coordinates $S(15,-8),B(-2,21)$ and $A(0,0)$

Using the distance formula.........

Length of side $SB = \sqrt{(15+2)^2+(-8-21)^2}= \sqrt{17^2+(-29)^2}= \sqrt{1130}$

Length of side $BA= \sqrt{(-2)^2+(21)^2}= \sqrt{445}$

Length of side $AS =\sqrt{(15)^2+(-8)^2}=\sqrt{289}=17$

So, the perimeter of the triangle will be: $(SB+BA+AS)= \sqrt{1130}+ \sqrt{445}+17 =71.71... \approx 72$ units. (Rounded to the nearest unit)

The height of the triangle for the corresponding base $SB$ is 8.89 units.

Formula for the Area of triangle, $A= \frac{1}{2}(base\times height)$

So, the area of the $\triangle SBA$ will be: $\frac{1}{2}(\sqrt{1130}\times 8.89)= 149.42... \approx 149$ square units. (Rounded to the nearest unit)

Answer:

75 ft

Step-by-step explanation:

Let 20/50 = 30/x

So,

20X = 30x50

20x = 1500

X = 1500/20

X = 75

Find dy/dx for (y^2/x) = 18 by implicit differentiation

Natasha2012 [34]

9514 1404 393

Answer:

dy/dx = y/(2x)

Step-by-step explanation:

The product formula can be used, along with the power rule.

d(uv) = du·v +u·dv

d(y^2/x) = d(18)

2y·dy/x -y^2/x^2·dx = 0

2x·dy -y·dx = 0 . . . . . . . . multiply by x^2/y

dy/dx = y/(2x) . . . . . . . . add y·dx, divide by 2x·dx

Can anyone help me with this question please I really need help please I’ll mark as brainliest

tia_tia [17]

Answer:

$f(x)=-11\times(7^x^-^1)$

Step-by-step explanation:

Stare at the numbers. Especially the first two. First one is -11. Second is $-11\times 7$ . Let's guess you keep multiplying. $-77\times 7=-539$ . Smells correct, let's confirm with the last one: $-539\times7 = -3773$ . I think we found a pattern. Each element is 7 times the previous one. With some practice you can just write the function, else let's divide by -11 away and let's see what we get:

$f(1) = 1=7^0; f(2)=7; f(3)=7^2; f(4)=7^3$ . Basically, the exponent is 1 less than the value we're evaluating the function. That leads tho the following

$f(x)=-11\times(7^x^-^1)$
