Answer:

Step-by-step explanation:

First, check to see which graph has a line going through the point (2,3). B and D are the only ones that have lines going through (2,3) (A comes close but it is not quite).

Next, you need to see which line would be parallel to the equation 3x-y=2. When two lines are parallel, they have the same slope. You have to turn that equation into point-slope formula (y=mx+b with m being the slope and b being the y-intercept). First, subtract 3x from both sides. You will then get -y=-3x+2. Then y needs to be alone (right now it has a -1 attached). Divide both sides by -1 to get y=3x-2. The number in front of the x is the slope, in this case, 3 or 3/1 (we do not care about the y-intercept, it will not help us in this problem since we are looking for a line parallel to this equation and so our line will not have the same y-intercept as this other equation). Since the line in parallel to that equation, we know that this line also has a slope of 3/1. Find the line between B and D that has a slope of 3/1, you get B (the line goes up 3 over 1).

Evaluate each expression for s=4 and t=8 1) (25)^2t 2) 2st^2-5^2 3) 2s^2-t^3/16

stepladder [879]

Answer:

1. 2.328× $10^{22}$

2. 487

3. 30.52 OR 0 (see explanation↓)

Step-by-step explanation:

1. $(25)^{2t}$

(sub for t=8)

= $25^{2*8}$

= $25^{16}$

=2.328× $10^{22}$

2. $2st^{2} -5^{2}$

(sub for s=4 and t=8)

=2×4× $8^{2}$ - $5^{2}$

=512-25

=487

3. $2s^{2} -t^{3/16}$ (the equation is not clear so I will do $2s^{2} -\frac{t^{3} }{16}$ as well)

FOR $2s^{2} -t^{3/16}$

(sub s=4 and t=8)

=2× $4^{2}$ - $8^{3/16}$

=32-1.476826146

=30.52 (to the nearest 2 decimal place)

FOR $2s^{2} -\frac{t^{3} }{16}$

(sub s=4 and t=8)

=2× $4^{2}$ - $\frac{8^{3} }{16}$

=32-32

Aughhhh i suck at this topic

NARA [144]

Answer:

x = 18

Step-by-step explanation:

The given angle is a right-angled triangle.

Such triangles have an angle that equals 90°.

The square attached at the base represents 90°. [Whenever you such a square between two sides, simply put the angle between those sides equal to 90.]

So, the points we know about this triangle:

One angle is = 90
Another angle given in the question is 72°.

*Property*

The sum of all angles in a triangle = 180

==> 90 + 72 + x = 180

==> 162 + x = 180

==> x = 180 - 162

==> x = 18

Answer:

5280 ft/1 mi, 1848 ft

Step-by-step explanation:

Whatever unit is given on the top (miles), you will write it on the bottom of the second fraction. Since we are solving for length in feet, we know that the numerator will be in feet. The only answer choice that has this option is 5280 ft/ 1 mi. You can check this math by taking 0.35 of 5280 feet, or 1 mile = 1848 ft.

$\frac{0.35 mi}{1} *\frac{?ft}{?mi}$

$\frac{0.35 mi}{1} *\frac{5280 ft}{1mi}$ (miles cancels out, left with feet)

$\frac{1848ft}{1}$

1848 feet

I hope this helps!
