Answer:
It is equal to 1 when raised to the zero power.
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Any number raised to the zero power equals 1. This is by definition to make the rules of exponents work.
Look at this example:
Any number (except zero) divided by itself equals 1.
For example, 25/25 = 1,
but 25 = 5²,
so 25/25 = 5²/5²
The rule of dividing two powers with the same base is to use the same base and subtract the powers.
5²/5² = 5^(2 - 2) = 5^0
By the rule of exponents, 5²/5² = 5^0,
but we saw above that 5²/5² = 25/25 = 1, so
5^0 must equal 1.
This led to the following definition of zero exponent.
Definition:
For any number a, a^0 = 1.
need help urgently vvvvvvv
Step-by-step explanation:
you understand coordinates and how to find them in the chart, yes ?
because I can't draw here, I can only give you the points through which the line has to go.
one point is, of course, (2, -3).
to find another good point we use the slope 3/4.
the slope is the ratio of y change/x change when going from one point to another.
so, we find another point with integer coordinates by e.g subtracting the slope units from the point (addition would also work) :
the other point on the line would be
(2 - 4, -3 - 3) = (-2, -6)
and then you draw a line that goes through both points.
I need the answer please and thank you
Answer: First do 145 - 25, which is 120. Then do 120 ÷ 15 = 8. Therefore the slope intercept is y ÷ 15 = x. Their voyage will last 8 days.

Find the measures of angles x and y in the figure.
Answer:
y = 35
x = 75
Step-by-step explanation:
Angles on a straight line = 180, so 180 - 45= 135.
Angles in a triangle = 180, so 180-105 = 75.

2x + 6 = 6x - 22 how many solutions does this have
Answer:
This equation has one solution.
Step-by-step explanation:
2x + 6 = 6x - 22
=> 28 = 4x
=> x = 7
This equation has one solution.

Find the perimeter. Simplify your answer.
add all the sides!
[side one] + [side two] + [side three]
[7y + 10] + [7y + 10] + [y - 4]
= 14y + 20 + y - 4
= 15y + 16
hope this helps :) !!
Answer:
15y + 16
Step-by-step explanation:
2(7y + 10) + y - 4
14y + 16 + y

Answer:
Multiply both sides by 6: 4x - 42 = 5
Step-by-step explanation:
(2/3)x - 7 = (5/6)
Multiply both sides by 6:
6*(2/3)x - 6*7 = 6*(5/6)
(12/3)x - 42 = 5
4x - 42 = 5
Write an equation in slope-intercept form for the line passing through the two points (0,-2) and (3,0)
Answer:
y = (2/3)x - 2
Step-by-step explanation:
This problem is interesting in that both the x- and the y-intercepts are given. The y-intercept is (0, -2), and so 'b' in 'y = mx + b' must be -2:
y = mx - 2. The x-intercept is (3, 0), so we know that y = 0 when x = 3:
0 = m(3) - 2
This latter result must be solved for m: 3m = 2, or m = 2/3.
Then the desired equation is y = (2/3)x - 2.

[tex]\sqrt\frac{7}{8}[/tex] In simplest radical form
Answer:
Step-by-step explanation:
[tex]\sqrt{\frac{7}{8} } = \sqrt{\frac{7}{8}*\frac{8}{8}[/tex]
= sqrt(56)/8
Answer:
(√14)/4
Step-by-step explanation:
You can "rationalize the denominator" after you take the root, or you can make the denominator a perfect square before you take the root.
[tex]\sqrt{\dfrac{7}{8}}=\dfrac{\sqrt{7}}{2\sqrt{2}}=\dfrac{\sqrt{7}}{2\sqrt{2}}\cdot\dfrac{\sqrt{2}}{\sqrt{2}}=\dfrac{\sqrt{14}}{4}\\\\\sqrt{\dfrac{7}{8}}=\sqrt{\dfrac{7}{8}\cdot\dfrac{2}{2}}=\sqrt{\dfrac{14}{16}}=\dfrac{\sqrt{14}}{4}[/tex]

Answer:
at an x intercept
Step-by-step explanation:
You need to calculate sin 0 = 0. Which means it's crossing (or at least touching) the x axis.

16. To get to school, Enzo can travel 1.2 km
east on Rutherford Street and then south
on Orchard Avenue to his school. Or, he
can take a shortcut through the park, as
shown. His shortcut takes him 20 min.
a
Rutherford Street
home
Orchard Avenue
shortcut
school
Enzo's walking speed is 6 km/h.
a) What angle does Enzo's shortcut make
with Rutherford Street? Describe any
assumptions you must make.
b) How much time does Enzo save by
taking his shortcut? Explain your answer.
Answer:
a)it is a 45 degree angle
b) Enzo saves 8 minutes if he takes the shortcut
Step-by-step explanation:
a) In the picture it looked like a square and if Rutherford street is 1.2 km so is Orchard avenue, and if its a true square it must be 90 degrees so you cut that is half and you get your answer of 45 degrees .
b) It takes Enzo 20 min to walk the shortcut and his walking speed is 6 km/h
you divide 20 by 1.3 or one third and you get 2 so the short cut is 2 km long, and we know Rutherford st. and Orchard ave. is 1.2 km each
2.4 km=length of Rutherford and Orchard together
shortcut is 2 km
divide 2.4 by 0.4 or .4 and you get 6
so if it takes him 20 min on the shortcut it should save him 8 minutes.

Use cross multiplication to figure this out. (What does xy = )
.78x/7 = 19/4y
Answer:
xy = 42.6282051282...
Step-by-step explanation:
0.78x/7 = 19/4y
0.78x * 4y = 3.12xy
19 * 7 = 133
3.12xy = 133
3.12xy/3.12 = 133/3.12
xy = 42.6282051282...

How do I know which region to shade for this inequality
y ≤ 2x + -4?
Answer:
You look at the sign between y and 2x
Step-by-step explanation:
To find which way to shade, look at your symbol. The symbol you have is a less than or equal to, you shade to the left. Because it has the line underneath, you have a closed circle. (This is for line plots so I don't know if this completely helps)
Hopefully it does help though!!
