A biologist investigates the growth of a special flower. It is estimated that
the height (in cm) of the flower is given by f(t) = at² + bt + C, where t is
the number of days passed since the start of the investigation. It is given
that the height of the flower first increases and then decreases.
What is the domain of f(t)?
Answer:
The domain of this function is:
Domain f(t): t ≥ 0
or
Domain f(t): {x ∈ R | t ≥ 0}
Step-by-step explanation:
Given the function of the height (in cm) of the flower
f(t) = at² + bt + C
Here,
t is the number of days passed since the start of the investigation.f(t) represents the height (in cm)Given that height of the flower first increases and then decreases.
The current function represents the quadratic function because it is of the form. Hence, the graph would be a curve.
f(x) = ax²+ bx + c
where a, b and c are the real numbers and a≠0
Normally the domain of quadratic is the set of all real numbers, but here in this case x-values consist of the time in terms of the number of days.
As the time in terms of a number of days can not be negative. Therefore, we conclude that:
The domain of this function is:
Domain f(t): t ≥ 0
or
Domain f(t): {x ∈ R | t ≥ 0}
What is the slope-intercept form of the linear equation x+4y=12?
Answer:
y = -x/4 + 3
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Standard Form: x + 4y = 12
Step 2: Rewrite
Find slope-intercept form
Subtract x on both sides: 4y = 12 - xDivide 4 on both sides: y = 3 - x/4Rearrange: y = -x/4 + 3we know that
The equation of the line in the slope-intercept form is equal to
we have
Solve for y
Subtract both sides
Divide by both sides
therefore
the answer is
Y= 1/4x+3

A painting is on sale at 40% off.the sale price is $320 what was the original price
Answer:
$533.33
Step-by-step explanation:
$533.33 multiplied by 0.6 = $319.998 which rounds to $320
533.33 ÷ 100 = 5.33 so this is 1 percent
5.33 x 40 = $213.332 which rounds to $213.33
$320 + $213.33 = $533.33
In triangle Jkl, l = 880 inches, Angle j=63° and Angle k=11°. Find the length of j , to the nearest
inch.
Answer:
j=816 inch
Step-by-step explanation:
J^+K^+L^=180° (sum of int. angles of triangle)
L^+11+63=180
L^=106°
j/sinJ=l/sinL
j/sin63=880/sin106
j*sin106/sin106=880*sin63/sin106
j=815.6
j=816 inch
The image of a point (1, 2) under a translation is (-5, -4) what is the translation vector
Answer:
u = vector (-6 , -6)
Step-by-step explanation:
u = vector(a , b)
Left (-) 6 units and down (-) 6 units
The translation vector for the image is (-6,-6).
What is a translation vector?A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another. Vectors are given in the form ( x y ) where x is the movement horizontally and y is the movement vertically.
For the given situation,
The image of a point (1, 2) under a translation is (-5, -4) .
The translation vector can be found by calculating the movement horizontally and vertically as
⇒ [tex](-5-1,-4-2)[/tex]
⇒ [tex](-6,-6)[/tex]
Hence we can conclude that the translation vector for the image is (-6,-6).

what is the value of x in the figure
Answer:
x is 35
Step-by-step explanation:
the two angles are opposite so they are equal
Answer:
x = 35°
Step-by-step explanation:
Vertical Angles
When two lines cross, two pairs of angles are formed. Those who are opposed by the vertex are called vertical angles and they are always congruent.
Congruent angles have the same measure.
Thus, the angle marked as x is opposed to 35° and they have the same measure, thus:
x = 35°

Answer: They received $14.58
Step-by-step explanation:
Set up a proportional relationship
If 2 cents equal to 3 cans then we will represent how 2,187 will be worth by x.
[tex]\frac{0.02}{3} / \frac{x}{2187}[/tex] Cross multiply

Step-by-step explanation:
I did this in 7th grade and had the answer but I don't know the steps
Answer: remember PEMDAS (parentheses, exponents, multiplication, division, addition, and subtraction. Multiplication and division)
answer is 16
Step-by-step explanation:
16×1+4(18÷2−9)
(Multiply 16 and 1 to get 16.)
16+4(18÷2−9)
(Divide 18 by 2 to get 9.)
16+4(9−9)
Subtract 9 from 9 to get 0.
16+4×0
Multiply 4 and 0 to get 0.
16+0
Add 16 and 0 to get 16.

if the equation of L1 is 4x-2y=6 what is the x intersept?
Write the equation of L in slope intersept form
Write the slope of L.
Answer:
The x intercept: (1.5, 0)
The slope intercept form: y = 2x - 3
The slope: m = 2
Step-by-step explanation:
x intercept means y=0
4x - 2y = 6
4x - 2·0 = 6
4x = 6
x = 1.5
The slope intercept form is: y = mx + b
4x - 2y = 6 {subtract 4x from both sides}
- 2y = - 4x + 6 {dividing both sides by (-2)}
y = 2x - 3 ← slope intercept form
Slope is the number by x, in slope intercept form of line's equation

If f(x) = 5x^2– 3 and f(x + a) = 5x^2+ 30x + 42,
what is the value of a ?
Answer:
The zeros are x=0,3,-2
There is a multiplicity of 1 for all of them.
Step-by-step explanation:
The required value of a is 3 for the given function.
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The function is given as follows:
f(x) = 5x²– 3
Substitute the value of x = x + a in the above function,
f(x + a) = 5(x + a)²– 3
f(x + a) = 5(x² + a² + 2ax) - 3
f(x + a) = 5x² + 5a² + 10ax - 3
f(x + a) = 5x² + 10ax + 5a² - 3 ....(i)
As per the question, we have f(x + a) = 5x²+ 30x + 42 ....(ii)
Equating the equations (i) and (ii),
So, 10a = 30
a = 30/10
a = 3
Therefore, the required value of a is 3.
