5750 divided by 3.78

Tems11 [23]

Answer:

1521.16402

Step-by-step explanation:

use fraction- division format $\frac{x}{y}$

$\frac{5750}{3.78}$

Multiply the numerator and denominator by 100

$\frac{575000}{378}$

Reduce by 2

$\frac{287500}{189}$

Now do long division

If z varies directly as x and z=30 when x=8 find z when x=4

dangina [55]

Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.

If you vertically compress the square root parent function f(x) = ^x, by 1/2 of a unit what is the equation of the new function

Naddik [55]

Answer:

The equation of the new function is $g(x) = \frac{\sqrt{x}}{2}$

Step-by-step explanation:

Suppose we have a function f(x).

a*f(x), a > 1, is vertically stretching f(x) a units. Otherwise, if a < 1, we are vertically compressing f(x) by a units.

f(x - a) is shifting f(x) a units to the right.

f(x + a) is shifting f(x) a units to the left

In this question:

$f(x) = \sqrt{x}$

Vertically compressing by 1/2:

This is the same as multiplying the function by 1/2. So

$\frac{1}{2} \times \sqrt{x} = \frac{\sqrt{x}}{2}$

The equation of the new function is $g(x) = \frac{\sqrt{x}}{2}$

Evaluate tan(Sin-1(-5/13)). Answer as a fraction please.

dangina [55]

Using pythagorean identities,tan(sin^-1(-5/13))= tan(arcsin(-5/13))

Let A = arcsin(-5/13) = -arcsin(5/13)

Thus, sin A = -5/13 and cos A = sqrt(1 - (5/13)^2) = 12/13.= tan(A)= sin(A) / cos(A)= -5/13 / (12/13)= -5/12
