7) What is the equation of a circle with the center (-8, 9) and the radius of 10?
Answer:
(x+8)² + (y - 9)² = 100Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)² + (y - b)² = r² where;
(a, b) is the centre of the circle
r is the radius
Given
Centre (-8, 9) where a = -8, b = 9
radius r = 10
Substitute into the formula to get the required equation;
(x-(-8))² + (y - 9)² = 10²
(x+8))² + (y - 9)² = 10²
(x+8)² + (y - 9)² = 100
Hence the required equation is (x+8)² + (y - 9)² = 100
match each equation with a value of x that satisfies it
options are:
5 , 9 , 18, 2, 1, -3

The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The expressions are given below.
[tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1
Then By simplification, we have
x - 2 = 2⁴
x = 16 + 2
x = 18
√x² + 7 = 4
x + 7 = 4
x = -3
∛(1 - x) = -1
1 - x = -1³
x = 2
The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.

The word particle can be used to describe a speck of dust, molecule, an atom or an electron. How can we avoid confusion in using the word particle?
Answer:
To avoid confusion in using the word "particle," one must state that a particle is an identifiable part of dust, a molecule, an atom, or an electron. This means that particles form these elements.
Step-by-step explanation:
For example, atoms are made up of three particles: protons, neutrons and electrons. These particles are each composed of even smaller particles known as quarks. Since quarks cannot be broken down further, they are the smallest particles known to mankind.

Find the balance of the account.
$1600 at 5% for 1 year
This is simple interest btw. I also need a explanation too
Answer:
$1680
Step-by-step explanation:
I = 5%
P = $1600
period = 1 year
$1600 + 15% = $1680
Answer:
$1680.
Step-by-step explanation:
The interest for 1 year = 1600 * 5%
= 1600 * 0.05
= $80.
So the new balance = old balance + interest
= 1600 + 80
= $1680.
write a quadratic function in standard form whose graph passes through (-5 0) (0,-8) and (4,0).
The required quadratic function in the standard form is f(x) = -1.25 x² + 5x.
What is a quadratic equation ?
A quadratic equation is an equation which contains a single variable of degree 2 and its general form is ax² + bx + c = 0.
The x - intercepts of the quadratic equation are (-5, 0) and (0 , -8). That meant (x + 5) and (x -0) are two factors of quadratic equation.
f(x) = a (x + 5) (x - 0)
f(x) = ax² + 5x
The graph of quadratic equation passes through (4 , 0). So we need to substitute x = 4 , f(x) = 0 in equation 1.
0 = a × 4² + (5 × 4)
0 = a × 16 +20
a = -20/16
We know that quadratic equation is in form ax² + bx + c = 0.
f(x) = [tex]\frac{-20}{16}[/tex] × x² + 5x
f(x) = [tex]\frac{-5}{4}[/tex]x² + 5x
f(x) = -1.25 x² + 5x
Therefore , the required quadratic function in the standard form is f(x) = -1.25 x² + 5x.

To combine two fractions into one fraction if they are being added / subtracted from each other, make it so they share the same denominator. To do this, one way is to make [tex]\frac{1}{3}[/tex] have denominator [tex]3t[/tex], so multiply the top and bottom of the fraction by [tex]t[/tex]:
[tex]\frac{t+2}{3t} - \frac{t}{3t}[/tex]
and now you can just subtract the numerator.
[tex]= \frac{t+2 - t}{3t} = \frac{2}{3t}[/tex]

6/8
Both have table of 2 in common so
3/4 is the simplest form
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
No. of remaining days = [tex]\frac{7}{8}[/tex] - [tex]\frac{1}{8}[/tex]
If the denominators are the same, you can directly do the working for the numerators while leaving the denominator alone.
[tex]\frac{7}{8}[/tex] - [tex]\frac{1}{8}[/tex] = [tex]\frac{6}{8}[/tex]
6 and 8 both have a common factor of 2, so we can further simplify this fraction.
[tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]
Thus, he must drive for [tex]\frac{3}{4}[/tex] more days.
