Answer:
(9.2 , 0)
Step-by-step explanation:
vertex: (4.6 , 12.2)
parabola: y = a (x-4.6)² + 12.2
pass (0,0): 0 = a (0-4.6)² + 12.2
a = - (12.2/21.16)
2nd root (x , 0): y=0
0 = a (x-4.6)² + 12.2 (x-4.6)² = - 12.2 / a = -12.2 / (- (12.2/21.16)) = 21.16
x - 4.6 = ± √21.16 = ± 4.6
x = 0 or x = 9.2

3x + 5 > 16
x is an integer.
Find the smallest value of x.
Answer:
4
Step-by-step explanation:
3x + 5 > 16
3x > 16 - 5
3x > 11
x > 11 / 3
x > 3.6666...
The smallest value would be 4.
Answer:
4
Step-by-step explanation:
Given
3x + 5 > 16 ( subtract 5 from both sides )
3x > 11 ( divide both sides by 3 )
x > [tex]\frac{11}{3}[/tex] , that is
x > 3 [tex]\frac{2}{3}[/tex]
If x is an integer then the smallest value of x is 4
A teacher is planning a class trip to the aquarium. The aquarium requires 2 chaperones for every 15 students. The teacher plans accordingly and orders a total of 85 tickets. How many tickets are for chaperones, and how many are for students?
Answer:
75 student tickets and 10 chaperone tickets
Step-by-step explanation:
First find out how many groups there are total by dividing 85 by 1 group total of 17 (15 students 2 chaperones).
85 / 17 = 5
Since you now know there are five groups of 15 students and 2 chaperones all you have to do is multiply 5 time 15 students and 5 times 2 chaperones.
15 x 5 = 75 for students
5 x 2 = 10 for chaperones

What is the definition of a tangent in math
Answer:
In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve. ... The word "tangent" comes from the Latin tangere, "to touch".
Step-by-step explanation:
A straight line touching a curve at a single point without crossing it there is tangent.

0 72 minutes
O 83 minutes
O 118 minutes
Answer:
72 mins
Step-by-step explanation:
The number of minutes Sam spent on exercising is 72 minutes. Therefore, option B is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given function is y = -0.78x + 95
Let x be the number of minutes of television Sam watched each day and y the number of minutes she spent exercising.
Here, x=30
Substitute x=30 in the given function, we get
y = -0.78(30)+95
= -23.4+95
= 71.6

The side of a hill makes a 12° with the horizontal. A wire is to be run from the top of a 175 foot tower on the top of the hill to a stake 120 ft down the hillside from the base of the tower. What length of wire is needed
Answer:
231.9ft
Step-by-step explanation:
We would be solving this problem by using the cosine rule.
The length = (pq)² + (qr)² -2 * pq * qr * cos102⁰
= 120² + 175² - 2*120*175 (-0.2079)
= 14400 + 30625 + 8731.8
= 53756.8
Length² = 53756.8
We take the square root of both sides
Length = √53756.8
Length = 231.89 feet
This is the length of the wire that is needed.

The line y = mx + c passes through the points (-2, 1) and (4,4).
Write down a pair of simultaneous equations involving m and c.
Solve the simultaneous equations.
Answer:
Step-by-step explanation:
Insert x for -2 & 4 and y for 1 & 4
1=-2m+c, 4=4m+c
solve the equation, m=1/2, c=2
Answer:
y = 1/2m + 2
Step-by-step explanation:
1 = -2m + c (1)
4 = 4m + c (2)
2 = -4m + 2c (1*)
(1*) + (2) = 6 = 3c
c = 2
y = mx + 2
4 = 4m + 2
2 = 4m
m = 1/2
so y = 1/2m + 2

What is the degree measure of ABC given that A=25 & C=135?
Answer:
m∠ABC = 110°
Step-by-step explanation:
By the property of exterior angle of a triangle,
"Exterior angle of a triangle is equal to the sum of two opposite interior angles"
m∠BAC + m∠ABC = 135°
25° + m∠ABC = 135°
m∠ABC = 135° - 25°
= 110°
Therefore, measure of angle ABC is 110°.

Which item in nature does NOT follow the Fibonacci Sequence *
Pinecone
Artichoke
Nautilus Shell
Pineapple
Answer:
all follow the sequence
Step-by-step explanation:
Pinecone and Pineapple - Scales and bracts are modified leaves, and the spiral arrangements in pine cones and pineapples reflect the spiral growth habit of stems. To confirm this, bring in a leafless stem from some tree or shrub and look at its buds, where leaves were attached.
Artichoke - The spiral of an artichokes leaves can be described by the Fibonacci Sequence. This sequence is a simple mathematical pattern where each successive number in the sequence is equal to the sum of the two preceding numbers, beginning with 0 and 1.
Nautilus shell - Each number is the sum of the two previous numbers. An approximation of a logarithmic spiral, created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34.
