the table shows the height of a plant as it grows. what equation in point slope form gives the plants height at any time
time(months)/height(cm)
3/15
5/25
7/35
9/45
Answer:
[tex]y - 15 = 5(x-3)[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line, in point slope form, is given by:
[tex]y - y_0 = m(x - x_0)[/tex]
In which the point is [tex](x_0,y_0)[/tex] and m is the slope.
3/15
This means that [tex]x_0 = 3, y_0 = 15[/tex]
So
[tex]y - 15 = m(x - 3)[/tex]
Finding the slope:
Suppose we have two points. The slope is given by the change in the output divided by the change in the input.
3/15
5/25
Change in the output: 25 - 15 = 10
Change in the input: 5 - 3 = 2
So
[tex]m = \frac{10}{2} = 5[/tex]
The equation is:
[tex]y - 15 = 5(x-3)[/tex]

A ladder is leaning against a building so that the distance from the ground to the top of the ladder is one foot less than the length of the ladder. Find the length of the ladder if the distance from the bottom of the ladder to the building is 5 feet.
A right triangle with the hypotenuse measuring x and one leg measuring x minus 1.
(1 point)
11 feet
14 feet
12 feet
13 feet
Answer:
Length of ladder (hypotenuse) = 13 ft
Step-by-step explanation:
Given:
Length of base (base) = 5 ft
Length of ladder (hypotenuse) = a
Distance between ground and ladder top (perpendicular) = a - 1
Find:
Length of ladder
Computation:
a² = 5² + (a-1)²
a² = 25 + a² - 2a + 1
2a = 26
Length of ladder (hypotenuse) = 13 ft
1/3 plus 1/4 so what is the answer to this question
Answer: 7/12
Step-by-step explanation:
1/3 + 1/4
1/3 = 4/4 * 1/3 = 4/12
1/4 = 3/3 * 1/4 = 3/12
4/12 + 3/12 = 7/12

Which is one reason why this expression is equal to 0?
[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62} [/tex]
Answer:
0
Step-by-step explanation:
The given expression is :
[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62}[/tex]
We can solve the expression as follows :
[tex]\frac{ - 5.62 + 5.62}{5.62}=\dfrac{0}{5.62}[/tex] (As -5.62+5.62 equals to 0)
Any number multipled to 0 gives 0.
Hence, the value of the given expression is equal to 0.

In ΔDEF, the measure of ∠F=90°, the measure of ∠E=41°, and FD = 79 feet. Find the length of DE to the nearest tenth of a foot.
Answer:
120.4ft
Step-by-step explanation:
Find the diagram in the attachment.
The triangle shown is a right angled triangle with the side DE as the hypotenuse, EF is adjacent side while DF is the opposite side.
To get DE, we will use the SOH CAH TOA trigonometry identity
Using CAH which is defined as:
Cos(theta) = Adjacent/Hypotenuse
Cos 79°= 23/Hypotenuse
Hypotenuse = 23/cos79°
Hypotenuse = 23/0.191
Hypotenuse = 120.4feet
DE = 120.4feet (to nearest tenth)

What is X equal to if 1X+30=6X+20?
Answer:
x=2
Step-by-step explanation:
1*x+30=6x+20
Multiply 1*x=x
x+30=6x+20
Subtract 30 from both sides:
x+30-30=6x+20-30
Simplify:
x=6x-10
Subtract 6x from both sides
x-6x=6x-10-6x
Simplify:
-5x=-10
Divide both sides by -5
-5x/5=-10/-5
Answer:x=2

Find angle picture below.
Answer:
Angle M = 63
Angle N = 96
Step-by-step explanation:
By exterior angle of triangle:
Angle M + Angle N = 159
(4y+3)+(6y+6)=159
y = 15
Angle M = 4y + 3 = 4(15) + 3 = 63
Angle N = 6y + 6 = 6(15) + 6 = 96
