tester [92]

Answer:

3×10x^{-8}

Step-by-step explanation:

0.00000003

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

How tall is the flag pole (please give explanation too)
Tpy6a [65]

Answer:

  22 3/4 ft

Step-by-step explanation:

The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.

<h3>Proportion</h3>

Shadow lengths are presumed proportional to the height of the object making them. This means ...

  h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet

Multiplying by 31 1/2, we get ...

  h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4

  h = 22 3/4 . . . . ft

The flagpole is 22 3/4 feet tall.

Three functions are given below: f(x), g(x), and h(x).
Rzqust [24]

Answer: The axis of symmetry is x=1.

Explanation:

The given function is,

g(x)=5x^2-10x+7

The degree of the equation is 2.  SInce it is a quadratic function therefore the graph of the function is a parabola.

The axis of symmetry of a parabolic function f(x)=ax^2+bx+c is a vertical line,

x=-\frac{b}{2a}

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,

x=-\frac{(-10)}{2(5)}

x=\frac{10}{10}

x=1

Therefore, the axis of symmetry is x=1.

Arrange from least to greatest, 4.3, 5.5, 6 1/6, 15/4, 4 3/8?
Sophie [7]
Here are the numbers
4.3 , 5.5 , 6\frac{1}{6} , \frac{15}{4} , 4\frac{3}{8}
I'm going to change them into fractions
In the fractions, divide the numerator by the denominator
6\frac{1}{6}<em />⇔6.1666---
\frac{15}{4}⇔3.75
4 \frac{3}{8}⇔4.375
Now to arrange them from least to the greatest
\frac{15}{4} , 4.3 , 4 \frac{3}{8} , 5.5 , 6\frac{1}{6}
