The points (1, 10) and (0, 2) fall on a particular line. What is its equation in slope-
intercept form?
0) Write your answer using integers, proper fractions, and improper fractions in simplest
form.
y = x +
Answer:
y = 8x + 2
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By this formula, slope of a line passing through (1, 10) and (0, 2) will be,
m = [tex]\frac{10-2}{1-0}[/tex]
m = 8
Equation of the line will be,
y = 8x + b
Since, this line passes through (0, 2),
2 = 8(0) + b
b = 2
Therefore, equation of the line will be,
y = 8x + 2
Answer:
y=3x+2

Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?
Answer: Greater than 10 N
Step-by-step explanation:
Given
Gravity force on metal is 10 N
But the metal piece is rising i.e. there must be an upward force greater than 10 N
Suppose the force is F
So, we can write
[tex]\Rightarrow F>10\ N[/tex]
Any force greater than 10 N is sufficient for the metal to move upwards
The greater the amount of force faster will be the movement
Hunter is going to invest in an account paying an interest rate of 1.7% compounded continuously. How much would Hunter need to invest, to the nearest cent, for the value of the account to reach $4,500 in 18 years?
Answer:
$3333.33 approx
Step-by-step explanation:
Given data
Rate r= 1.7%
Final Amount A=$4500
Time = 18years
Principal P= ????
The expression for the compound interest is given bellow as
A=P(1+r)^t
4500= P(1+0.017)^18
4500= P(1.017)^18
4500= P*1.35
P= 4500/1.35
P= $3333.33
Hence the principal is $3333.33 approx

B. (-3,0)
C. (2,3)
D. (-2,-3)
Answer:
x=107/2, y=-40. (107/2, -40).

To Find :
complete the table
calculate and estimate for the mean
The estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.
a) To complete the table, we need to find the values of "fx" (frequency multiplied by the midpoint) for each class interval. Here's the updated table:
Number of Nuts Number of Packets Midpoint (x) fx
4-6 5 5 5 * 3 = 15
7-9 8 8 8 * 9 = 72
10 - 12 11 11 11 * 12 = 132
13 - 15 14 14 14 * 17 = 238
16 - 18 17 17 17 * 9 = 153
Total 50 610
b) To calculate an estimate for the mean, we use the formula:
Mean = Sum of (fx) / Total Number of Packets
Mean = 610 / 50
Mean ≈ 12.2
Therefore, the estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

Yesterday 56 people came to the Center, How many people came to the Center to hike if: 30 people took classes,22 went bird-watching, and l2 people did both?
Answer:
40 people came to the Center to hike
Step-by-step explanation:
30 people took classes
22 did bird watching
12 did both
to solve, take 12 and subtract it from each one:
⇒ 30 - 12 = 18
⇒ 22 - 12 = 10
18 people only took classes
10 people only did bird watching
12 people did both
18 + 10 + 12 = 40

9514 1404 393
Answer:
(c) (6x^4 – 4)(36x^8 + 24x^4 + 16)
Step-by-step explanation:
The correct factoring can be found by looking at the first exponent in the second set of parentheses.
The factorization of ...
(a^3 -b^3)
is ...
(a -b)(a^2 +ab +b^2)
__
Here, you have a=6x^4 and b=4, so the first term in the second parentheses is ...
a^2 = (6x^4)^2 = 6^2·x^(4·2) = 36x^8 . . . . matches the 3rd choice

Answer:
5 bowls
Step-by-step explanation:

17/8 ÷ 3/8
Convert 1 7/8 to improper fraction = 15/8
15/8 x 8/3 = 5 bowls
The shorter leg of a right triangle is two less than the hypotenuse. The longer leg is one less than the hypotenuse. Find all three sides of the triangle. HELP TEST!
Answer:
x = 5
Step-by-step explanation:
using the Pythagorean theorem:
(x-1)² + (x-2)² = x²
x²-2x+1 + x²-4x+4 = x²
reduce:
2x²-6x+5 = x²
subtract x² from each side:
x²-6x+5 = 0
(x-1)(x-5) = 0
x=1 but because shorter leg would be 0, a triangle would be impossible.

Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A (-5, 12) B (11, 0) 1 :3
Answer:
(7, 3)
Step-by-step explanation:
Using the midpoint formula
M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}
X = ax1+bx2/a+b
X = -5(1)+3(11)/1+3
X = -5+33/4
X = 28/4
X = 7
Y = ay1+by2/a+b
Y = 1(12)+3(0)/1+3
Y = 12/4
Y = 3
Hence the coordinate of P is at (7, 3)
