Need help solving this
Answer:
Part A: h(t) = ⅔t + 64
Part B: The toddler's height increases by 0.67 cm for every increase in age of 1 month.
Step-by-step explanation:
Given the graph of a linear function that models the relationship between the height, h, and age in months, t.
Part A:In order to establish the linear function, we must first identify the slope or the rate of change to further gain an understanding how the height varies with age over time. To solve for the slope, choose two points from the graph:
Let (x₁, y₁) = (18, 76)
(x₂, y₂) = (21, 78)
Substitute these values into the following slope formula:
[tex]\mathsf{\textbf\:m = \frac {(y_2\: -\: y_1)}{(x_2\: -\: x_1)}}[/tex]
[tex]\mathsf{\textbf\:m = \frac {78\: -\:76}{21\: -\: 18}\: =\:\textbf\:\frac{2}{3}}[/tex]
Therefore, the slope of the line is ⅔.
To find the y-intercept, or the initial value for the height, use the slope, m = ⅔, and another point from the graph, (18, 76), to solve for the y-intercept, b.
h(t) = ⅔t + b
76 = ⅔(18) + b
76 = 12 + b
Subtract 12 from both sides:
76 - 12 = 12 - 12 + b
64 = b
Hence, the linear function that expresses the height as a function of age is:
h(t) = ⅔t + 64.Part B:Based on the graph, the toddler's height increases by 0.67 cm for every increase in age of 1 month. Between the ages of 15 and 18 months, a toddler grows by 2 cm. Solving algebraically, we can determine how much the toddler grew by the 16th month by substituting t = 16 into the function:
h(16) = ⅔(16) + 64
h(16) = 10.67 + 64
h(16) = 74.67
It shows on the graph that the toddler's height at 15 months is 74 cm. Our solution here in Part B shows that the toddler grew 0.67 cm by the 16th month.

Arsenic-74 is used to locate brain tumors. It has a half-life of 17.5 days. 90 mg were
used in a procedure. Write an equation that can be used to determine how much of
the isotope is left after x number of half-lives.
The exponential function that can be used to determine how much of the isotope is left after x number of half-lives is given by:
[tex]A(x) = 90(0.5)^x[/tex]
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, the initial amount is of A(0) = 90 mg, and we are working with half-lifes, hence r = 0.5, which means that the equation is:
[tex]A(x) = 90(0.5)^x[/tex]

A car is traveling at a steady speed. It travels 2 1/2 miles in 3 1/3 minutes. How far will in 49 minutes? In 1 hour ?
2 1/2 miles / 3 1/3 minutes = 3/4 mile per minute
A. 3/4 mile per minute x 49 minutes = 35 3/4 miles
B 3/4 miles per minute x 60 minutes (1 hour) = 45 miles
Answer:
2 1/2 miles = 5/2 miles
3 1/3 minutes = 10/3 minutes
Here,
in 10/3 minutes travels = 5/2 miles
in 1 minutes travels = (5/2)/(10/3) miles
in 49 minutes travels = (49*(5/2))/(10/3) miles = 36.75 miles
in 60 minutes (1 hour) travels = (60*(5/2))/(10/3) miles = 45 miles

Answer:
C
Step-by-step explanation:
The red graph is shifted right by 1 from the black graph, so its function would be f(x -1) before it is reflected across the x-axis. Normally, such a reflection will be done by multiplying f(x) by a negative number. Here, that negative number is used to divide y, instead.
The transformation would normally be expected to be ...
y = -1·f(x -1)
By dividing by -1, this becomes ...
y/(-1) = f(x -1) . . . . . . equation of the red graph

Step-by-step explanation:
Answer: 11 is C and 12 is D.
Step-by-step explanation: On number 11, go on the calculator or just do on paper because you could put 175 over 100 then 60 over a 100 and cross multiply then divide. Once you have the answer, you have to take out the 6%. Now on number 12, an easy way to check. Is to go on Desmos. I used Desmos in 8th grade and it helped me cheat easily. :)

factor the trinomial 6x2 + 7x + 2
Answer:
(3x+2)(2x+1)
Step-by-step explanation:
when we factor this equation we apply method such that what are two numbers sum of them gives 7 and product of them is 12( let say coefficent of x^2=a, coefficent of x=b and the constant term=c then; to factor this we say two numbers addition of them gives us <b> and product of them gives us <a×c> , so those numbers become 3 and 4 because when we add they give 7 and when we multiply they give 12 .let as factor the equation the term 7x become 3x+4x6x^2+3x+4x+23x(2x+1)2(2x+1)we take one of the two equations found in bracket and we place the two terms found out side of the bracket togather in bracket as follows3x(2x+1)2(2x+1)(2x+1)(3x+2) this is a factord form of the above equationI think it is helpful for youWrite a function for the area of a triangle

Answer:
For the function f(x) = 3x - 8,
f(0) = -8
f(4) = 4
f(-4) = -20
f(1/3) = 7
Step-by-step explanation:
Given:
f(x) = 3x - 8
f(0) = 3(0) - 8
f(0) = 0 - 8
f(0) = -8
f(4) = 3(4) - 8
f(4) = 12 - 8
f(4) = 4
f(-4) = 3(-4) - 8
f(-4) = -12 - 8
f(-4) = -20
f(1/3) = 3(1/3) - 8
f(1/3) = 1 - 8
f(1/3) = 7

Answer:
[tex]y = \frac{5}{2} x + 16[/tex]
Step-by-step explanation:
Substitute the slope and the point into y = mx + b and solve for "b"
[tex]y = mx + b[/tex]
[tex]1 = \frac{5}{2} (-6) + b[/tex]
[tex]1 = -15 + b[/tex]
[tex]16 = b[/tex]
