Round 87671.5613658 to the nearest thousand

1 answer:

8 0

To round the number 87671.5613658 to the nearest thousand, or the place value that is four to the left of the decimal, which would be the 7 bolded below:
87671.5613658

Consider the number to the right of it, 6. If the number is below 5, then you would round down to 87000 and if the number is 5 and above, then you round up to 88000. Because 6 is 5 and above, you would round up to 88000 which would be your answer. :)

Find the axis of symmetry and what direction the parabola opens. -1/4(y+4)=(x-3)²

MariettaO [177]

First, convert the equation to the standard equation of a parabola.
-1/4(y+4)=(x-3)^2 ---multiply -4 on both sides
y+4=-4(x-3)^2 ---subtract 4 on both sides
y=-4(x-3)^2-4
From the equation, we know that the parabola was moved by 3 to the right, because of (x-3)^2. So the axis of symmetry is x=3. Now look at the number in front of (x-3)^2. It is -4. Since it is negative, the parabola opens downwards.

Answer:

the pattern step number of second step is added to number of balls used of first step to get number of balls used of second step

that is

1 + 2 ( number of balls added to pattern step number) = 3 (number of balls used)

in the same way

6 + 4 = 10 ( first blank )

5 + 10= 15 ( second blank)

15 + 7 = 22 ( third blank )

22 + 8 = 30 ( fourth blank)

Please help me solve this

Answer:

1st pic:

x = 49

top angle = 45

bottom angle = 108

far right angle = 27 degrees

2nd pic:

angle 1 = 88 degrees

angle 2 = 57 degrees

angle 3 = 35 degrees

angle 4 = 145 degrees

Step-by-step explanation:

1st pic:

you can find the far right angle by taking 153 and subtracting it from 180:

⇒ 180 - 153 = 27 degrees

you can find x by the following equation ⇒ x - 4 + 2x + 10 + 27 = 180

combine like terms ⇒ 3x + 33 = 180

subtract 33 from each side ⇒ 3x + 33 - 33 = 180 - 33 ⇒ 3x = 147

divide 3 on each side: ⇒ $\frac{3x}{3} = \frac{147}{3}$

x = 49

to find the top and bottom angles, substitute 49 for x:

top angle : x - 4

49 - 4 = 45 degrees

bottom angle: 2x + 10

2 x 49 + 10 = 108 degrees

2nd pic:

angle 1:

⇒ 180 - 92 = 88 degrees

angle 2:

⇒ 180 - 123 = 57 degrees

angle 3:

⇒ 180 - (88 + 57) = 35 degrees

angle 4:

⇒ 180 - 35 = 145 dgerees
