How many significant digits are in the number 8.1000?

2 answers:

8 0

D.5 The number before the decimal point is not a zero, therefore, it is significant. All numbers after the zero are significant as well because the 1 followed by 3 zeros indicates the place of the numbers (hundreds, thousandth, ten thousandths.)

I hope this helps!

There are 5 significant digits. Significant digits are those that can be measurable - it indicates the accuracy of the measuring or the instrument of measuring. If the number is represented with four decimal numbers it means that the instrument is sensitive up to that detail in the measuring.

1. Write the equation for a line in point slope form that had a slope of 4 and passes through (1,1)

Dahasolnce [82]

Solution:

Note that:

Slope = m = 4
Given point: (x₁,y₁) = (1,1) [x₁ = 1; y₁ = 1]
Formula: y - y₁ = m(x - x₁)

Use the formula to convert the line in point slope form.

y - y₁ = m(x - x₁)
y - 1 = 4(x - 1)

The equation of the line (In point slope form) is y - 1 = 4(x - 1).

In circle O, BC=14 and DC=25. What is the length of diameter BA? -58.6 -12.2 -44.6 -30.6

Savatey [412]

The picture in the attached figure

we know that
If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment
so
DC²=BC*CA-----> CA=DC²/BC
DC=25
BC=14
CA=25²/14-----> CA=44.64
CA=BC+BA----> BA=CA-BC----> BA=44.64-14----> BA=30.64

BA is the diameter
hence
the length of diameter BA is 30.64----> round to the nearest tenth---> 30.6

the answer is
the length of diameter BA is 30.6

What is the general form of the equation of a circle with its center at (-2,1) and passing though (-4,1) ?

julsineya [31]

Equation is :( x + 2 )² + ( y - 1 )² = r²( - 4 + 2 )² + ( 1 - 1 )² = r²4 = r², than we will plug in to a formula:( x + 2 )² + ( y - 1 )² = 4x² + 4 x + 4 + y² - 2 y +1 = 4x² + y² + 4 x - 2 y + 1 = 0
the answer is : x2 + y2 + 4x − 2y + 1 = 0
