Ella measured the height of a in inches every week for four weeks after planting it what is the best prediction for the height of the plant after 12 weeks
Complete question is;
Elle Measured the height of a plant, in inches,Every week for four weeks after planting it.
The height of the plant, h, in inches, Can be modeled by the function h(t) = 1.5t + 3, where t represents the time in weeks.
Based on this model, what is the best prediction for the height of the plant after 12 weeks?
A 16.5 inches
B 21 inches
C 22.5 inches
D 27.3 inches
Answer:
Option B: 21 inches
Step-by-step explanation:
We are given the function h(t) = 1.5t + 3, where t represents the time in weeks.
At t = 0;
h(0): 1.5(0) + 3 = 3inches
At t = 1;
h(1): 1.5(1) + 3 = 4.5 inches
Thus, after 12 weeks, height will be;
h(12): 1.5(12) + 3 = 21 inches
Option B is correct

The co-ordinates of D is if the midpoint E is at (-1,0 )which is calculated using the section formula.
In coordinate geometry, the Section formula is used to determine the internal or external ratio at which a line segment is divided by a point. It is used to determine a triangle's centroid, incenter, and excentre.
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
The section formula is given by:
[tex]{\displaystyle P=\left({\frac {mx_{2}+nx_{1}}{m+n}},{\frac {my_{2}+ny_{1}}{m+n}}\right)}[/tex]
where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.
The midpoint is calculated by:
[tex]{\displaystyle Q=\left({\dfrac {x_{1}+x_{2}}{2}},{\dfrac {y_{1}+y_{2}}{2}}\right)}[/tex]
where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.
Now the given co-ordinates of the points are C(5, 2) and the midpoint is E(-1 , 0). Now to find the co-ordinates of D we have to use the midpoint formula.
Let the co-ordinate's of D be (a , b) then by using the above midpoint formula we get:
-1 = (5+a) ÷ 2
or, a = -2 -5
or, a = -7
again
0 = (2+b) ÷ 2
or, b = -2
Hence the co-ordinates of D is (-7 , -2)

D. ∠BDE ≅ ∠ADE
E. ∠CAB ≅ ∠DAC
Answer:
The Answer is A) ABC is congruent to DBE
Step-by-step explanation:
Correct on PLATO
The missing step in the proof is ∠ABC ≅ ∠DBE by the reflexive property of congruence option (A) is correct.
What is congruence in the triangles?The measurements of the sides and angles of two or more triangles determine their congruence. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of corresponding sides and angles of two triangles are equal, they are said to be congruent.
From the two triangles:
ΔABC and ΔDBE
As we can see in the two triangles, the angle ∠ABC and ∠DBE are the same.
So, by the reflexive property of congruence:
∠ABC ≅ ∠DBE
Thus, the missing step in the proof is ∠ABC ≅ ∠DBE by the reflexive property of congruence option (A) is correct.

18. Nine cartons of juice cost the same as 5 fruit cups. Also, one fruit cup costs 50¢ more than one bowl of soup, while one bowl of soup costs 50¢ more than one carton of juice. What would be the cost of each item: a carton of juice, a fruit cup, and a bowl of soup?
Answer: bowl of soup=$1.75
carton of juice=$1.25
fruit cup=$2.25
Step-by-step explanation:
j=carton of juice. f=fruit cup. s=bowl of soup.
9j=5f
f=s+0.5 ==> 0.5 dollars is 50 cents
s=j+0.5
j=s-0.5
9(s-0.5)=5(s+0.5)
9s-4.5=5s+2.5
4s-4.5=2.5
4s=7
s=7/4
s=$1.75
s=j+0.5
1.75=j+0.5
j=$1.25
f=1.75+0.5
f=$2.25

Huey is reading a book that is 697 pages long. He tells a friend that he is about 3/4 of the way done. About how many more pages must Huey read before he finishes the book?
is it
A.160
B.175
C.250
D.150
Answer:
B. 175
Step-by-step explanation:
There are 2 ways that we can find the answer to this question:
1. Take 1/4 of 697
2. Take 3/4 of 697 and minus the product from 697.
Let's do it both ways:
If we are doing it the first way it would look like this:
(1/4)(697) = 175
Note that we get 1/4 because Huey already read 3/4 of the book so he has 1/4 left.
The second way would look like this:
(3/4)(697) = 523
679 - 523 = 174 (roughly 175)
Therefore, the answer to your question would be B. 175.

True or False? A circle could be circumscribed about the quadrilateral below.
Answer: b. false
Step-by-step explanation:
Yes, A circle could be circumscribed about the quadrilateral below.
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
A circle can be circumscribed around the four vertices of a quadrilateral
if and only if,
both pair of opposite angles inscribed in the quadrilateral are supplementary to each other.
By supplementary to each other we mean that their sum is equal to 180°.
we have,
In this case we have opposite interior angles supplementary to each other hence we can circumscribe a circle around it.
Such Quadrilateral are called cyclic quadrilateral.
Hence, Yes, A circle could be circumscribed about the quadrilateral below.

The value of x for which 3 (x-2) = 2 (x+1)
Answer:
x = 8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
3(x - 2) = 2(x + 1)
Step 2: Solve for x
Distribute: 3x - 6 = 2x + 2Subtract 2x on both sides: x - 6 = 2Add 6 to both sides: x = 8Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(8 - 2) = 2(8 + 1)Subtract/Add: 3(6) = 2(9)Multiply: 18 = 18Here we see that 18 does indeed equal 18.
∴ x = 8 is a solution to the equation.

The store is selling lemons at $0.66 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make three 9-inch lemon pies,each requiring half a cup of lemon juice
Answer:
It will cost $7.92
Step-by-step explanation:
We will need to find out how many table spoons of lemon we will need first.
We need to make 3 pies requiring half a cup of lemon juice.
3 * 1/2 = 1.5 cups
We convert the cups to tablespoons
1.5 * 16 = 24 tablespoons
Then, since each lemon yields two tablespoons, we divide the tablespoons required by two. This is to find the number of lemons we need.
24/2 = 12
We multiply lemons by the price the store is selling them.
12 * $0.66 = $7.92
This is the price to buy enough lemons to make the 9-inch lemon pies.
cauculate the mass of the sun
The mass of the sun using Newton's form of Kepler's 3rd law is;
M = 1.99 * 10³⁰ kg
How to calculate the mass of the sun?
Newton's form of Kepler's 3rd law shows us the orbit of a planet around the Sun. This relates the semi major axis distance of the orbit to the period of the orbit using the equation:
p² = (4π²/GM) * a³
Where:
p is the orbital period;
G is the gravitation constant;
M is the mass of the Sun;
a is the orbit semi major axis distance.
Making M the subject gives;
M = (4π²a³/Gp²
Plugging in;
Now for planet Earth:
a = 1.496 * 10¹¹m
p = 3.154 * 10⁷ s
Putting in those values to find M is;
M = 1.99 * 10³⁰ kg

Domain of r(x) = |x| is ( −∞, ∞ ) , { x | x ∈ R }
Range of r(x) = |x| is [ 0 , ∞ ) , { y | y ≥ 0 }
The domain of a function is defined as the set of values that we are allowed to enter into the function. This set is a bunch of x values in a function such as r(x).
The domain of the given function r(x) is all real numbers except where this expression, r(x) = |x| is undefined. In this question, there is no real number that makes this expression undefined.
The interval is denoted as ( −∞ , ∞ ).
The set builder is denoted as { x | x ∈ R }.
The range of a function is defined as the set of values that the function can assume. This set is a bunch of the values that the function shoots out after we enter a x value in. The range is a set of all valid y values. We have to use the graph to find the range.
The interval is denoted as [ 0 , ∞ )
The set builder is denoted as { y | y ≥ 0 }
