Answer:

(a) 3

(b) 4

Step-by-step explanation:

To find the number of significant figure, ignore all zeros on the left and count the remaing digits.

(a) ignore 0.0, so 590 is 3 s. f.

(b) no zeros to the left, so 4 s. f.

In variogram modeling with multiple variables and anisotropy, if all the variograms cannot be modeled well, it is critical to mo

siniylev [52]

Answer:

The statement is false.

Step-by-step explanation:

If the modeling is with multiple variables it is necessary for all the variables to be modeled well such that the criticality of the model is dependent on all the variograms. It is not dependent on the cross variograms only.

The equation y−5=−2(x−3) is in point-slope form. Which shows this equation in slope-intercept form?

MAXImum [283]

y - 5 = -2(x - 3)

Distribute -2.

y - 5 = -2x + 6

Add 5 to both sides.

y = -2x + 11

B) y = -2x + 11

Find the missing side lengths. leave your answers as radicals in simplest form.

Murrr4er [49]

Answer:

x = 4 , y = 2

Step-by-step explanation:

Using the sine / tangent ratios in the right triangle and the exact values

sin60° = $\frac{\sqrt{3} }{2}$ and tan60° = $\sqrt{3}$ , then

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{2\sqrt{3} }{x}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

x $\sqrt{3}$ = 4 $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

x = 4

and

tan60° = $\frac{opposite}{adjacent}$ = $\frac{2\sqrt{3} }{y}$ = $\sqrt{3}$ ( multiply both sides by y )

y $\sqrt{3}$ = 2 $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

y = 2
