Answer:
D. 32,154
Step-by-step explanation:
54,267 can be written as 54267.0
The 2 in 54 267 should be move 1 place to the left to indicate your multiplying by 10
Moving 1 space to the left = Times 10
Moving 2 places to the left = Times 100
Moving 3 places to the left = Times 1000
Answer:
a) y-int is at (0, 8)
b) zeros are at (0.8, 0) and (-3.2, 0); after having rounded to the nearest tenth.
Step-by-step explanation:
Given that y = -3x² - 7x + 8
we can find our y-intercept by setting x = 0
y = -3 (0)² - 7 (0) + 8
y = 8
so, our y intercept is at (8, 0)
To find our zeros, or x-intercepts, we need to set y = 0
0 = -3x² - 7x + 8
Let's use the quadratic formula
x = (-b ± √(b² - 4 (a * c))) / 2a
where, in this case
a = -3
b = -7
c = 8
x = (7 ± √((-7)² - 4 (-3 * 8))) / (2 * -3)
x = (7 ± √(49 - -96) / -6
x = (7 ± √145) / -6
using the addition pathway
x = (7 + √145) / -6
x = 3.2
using the subtraction pathway
x = (7 - √145) / -6
x = -0.8
So, our x-intercepts, or zeros, will lie on the points
(0.8, 0) and (-3.2, 0)
Create a table of x and y values using the given equation, and plot and graph. Clearly label your y and x intercepts.
(x, y)
(-3, 2)
(-2, 10)
(-1, 12)
(0, 8)
(1, -2)
(2, -18)
(3, -40)
Answer:
Step-by-step explanation:
Thales theorem tells us that B is a 90
and therefore from W to o (center) is 45°
we know the total of the arc VoW is 98
180= 8x +1 + 45 +98
36 = 8x
4.5 = x
x = 4.5
C . bc its the right answer :)
1. All whole numbers (0, 1, 2,...) and their negative equivalent ( -1, -2, -3, ...) are considered integers. Hence, from the choices provided, the answer would be A.
2. Real numbers consist of rational and irrational numbers. So the statement "Every real number is a rational number" is not correct. Thus, the answer is D.
3. 5.85, 63.4, and 27.5 are terminating decimals. This means that they have a fixed decimal conversion and does continue endlessly. Meanwhile, for 8.52624 . . ., its digit goes on forever. So, odd one out would be C.
4. Irrational numbers are those that cannot be expressed as the ratio of two numbers. Examples for this would be the value of the constant e, √2, etc. Rational numbers, on the other hand, are numbers that can be expressed as ratio of two numbers. As can be seen irrational and rational numbers are opposite of ech other, by definition. Hence, irrational numbers cannot be classified as rational numbers. That will give an answer of E.
5. From the previous items, we can see that both rational and irrational numbers are part of the real number system. This means that every irrational number is a real number. Hence, the answer is C.
