Answer:
A, A and A
Step-by-step explanation:
Given
y = ax² + bx + c ( a ≠ 0 )
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
The graph here is a maximum, thus a < 0 → A
--------------------------------------------------------------------
The value of c is the y- intercept of the graph ( when x = 0 )
Since the y- intercept is below the x- axis then c < 0 → A
--------------------------------------------------------------------
The solutions to the equation are where the graph crosses the x- axis ( y = 0 )
Since the graph crosses the x- axis to the left of the y- axis, then
both solutions are negative → A

Given f(x) = 3x- 1 and g(x) = 2x-3, for which value of x does g(x) = f(2)?
Options:
A)x=3/2
B)x=2
C)x=5/2
D)x=4
Answers
Answer: x = 4
Step-by-step explanation: f(2) = 3(2)-1 = 5. Meaning x needs to be a value that makes g(x) = 5. You can set them up equal to each other 5 = 2x-3 and solve. You end up getting x = 4.

Answer:
Volume of the prism: 120cm^3
Step-by-step explanation:
volume of a prism = area of cross-section x length
so
volume of triangular prism = 4 (h) x 6 (b) divided by 2 x 10 (length)
6 x 4 = 24
24 / 2 = 12
12 x 10 = 120

“Identify the CORRECT formula based on the sequence” do not answer on some bs .
Answers
Answer:
see explanation
Step-by-step explanation:
there is a common ratio between consecutive terms , that is
21 ÷ 7 = 63 ÷ 21 = 3
this indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ration
here a₁ = 7 and r = 3 , then
[tex]a_{n}[/tex] = 7 . [tex]3^{n-1}[/tex] ← explicit formula
the recursive formula allows a term to be found by multiplying the previous term by r , then
[tex]a_{n}[/tex] = 7 . [tex]a_{n-1}[/tex] ← recursive formula
The diameters of cherry tomatoes produced by a large farm have an approximately Normal distribution, with a mean diameter of 22 mm and a standard deviation of 2.5 mm. What proportion of such tomatoes have a diameter between 20 and 26 mm?
Answers
Answer:
0.7333
Step-by-step explanation:
2021 Math
Proportion of such tomatoes have a diameter between 20 and 26 mm is 0.7333.
What is standard deviation?It's a way to measure how far each data point is spread from the average value.
let x represents the diameters of cherry tomatoes produced by large farm which is formally distributed with mean = 22m
and, standard deviation= 2.5 mm
Now, proportion of tomatoes have diameter between 20 and 26 mm
=P (20 < x< 26)
=P(20-22 / 2.5 < [tex]x- \mu/ \sigma[/tex] < 26- 22/2.5)
=P(-0.8 < z < 1.6)
=P(z = 1.6) - P(z=-0.8)
=0.9452 - 0.2119
==0.7333
Hence, proportion of such tomatoes have a diameter between 20 and 26 mm is 0.7333.

12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.
