I need help ! I need to find the axis of symmetry, the vertex, the x-intercept(s), the y-intercept(s) and the concavity!!!!!
Answers
Answer:
Step-by-step explanation:
From the figure attached,
A parabola has been graphed.
Vertex of this parabola → (-1, -4) (lowest point)
Axis of symmetry → x = -1 (Parabola is symmetric about the vertical line x = -1 parallel to the y-axis)
x- intercepts (points of intersection of the parabola and x-axis) → (-1, 0) and (1, 0)
y- intercepts (point of intersection of the parabola and y-axis) → (0, -3)
Concavity of the parabola → Concave UP

Answers
Answer:
125
Step-by-step explanation:
For the first digit of our number, we have 5 options (1, 2, 3, 4, 5). For the second and third digits, we still have 5 options because the digits can be repeated. This means that the total different numbers we can make is 5 * 5 * 5 = 125 numbers. Hope this helps!

How many solutions for x does the following equation have? 4/5 (20x+5) = 16x-2 A. infinite B. 1 C. -2 D. 0
Answers
Answer :
A. infinite
Step by step4/5 (20x + 5) = 16x - 2
16x + 4 = 16x - 2
16x - 16x = -2 - 4
0x = -6
x = -6/0
x = infinite
The equation has zero solution.
What is the solution to a linear equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
Given here, the expression as 4/5 (20x+5)=16x-2
80x+20 = 80x-10
20 =- 10 which is not possible
Hence, the equation has no solution and thus D is the correct option.

A locker combination has three nonzero digits, and the digits cannot be repeated. The first two digits are 1 and 2. What is the probability that the third digit is 3?
Answers
Answer:
Approximately 14% or 1/7
Step-by-step explanation:
To solve this problem, first find the ratio of 3 to the possible numbers.
There are 9 possible digits in one space on a non-zero combination lock. However, digits cannot be repeated, and 1 and 2 are already taken. Therefore, there are 7 possible digits (9 - 2 = 7). Therefore, the ratio of getting a 3 to possible digits is 1:7, as there is 1 '3' and 7 others.
As a fraction, 1:7 is 1/7. As a percentage, 1/7 is about 14%. Therefore, there is approximately a 14% chance that the third digit will be 3.

Use a calculator to find angle theta for which tan theta = 2. Round to the nearest hundredth.
Answers
Answer:
in degrees: theta = 63.43°
in radians: theta = 1.11 rad
Step-by-step explanation:
To find the value of the angle theta that gives us tan(theta) = 2, we should use the inverse function of the tangent in the calculator, that is, the arc tangent function.
Then, if we use the arc tangent function (in some calculators, it may be shown as 'atan' or 'tan^-1') in the value 2, we would find:
atan(2) = 63.435°
So the angle theta that gives us tan(theta) = 2 is theta = 63.43°.
Be sure to check in the calculator if the answer is given in degrees or radians.
In radians, we would find theta = 1.1071 rad (rounded to nearest hundredth: theta = 1.11 rad)

Answers
Answer:
Total number of ways are 336.
Step-by-step explanation:
It is required to find the number of ways in which we can award a 1st, 2nd and 3rd place prize among eight contestants. It means we need to find the number of permutations. We need to find [tex]^8P_3[/tex].
Here, r = 3
So,
[tex]^nP_r=\dfrac{n!}{(n-r)!}\\\\^8P_3=\dfrac{8!}{(8-3)!}\\\\^8P_3=\dfrac{8!}{5!}\\\\^8P_3=\dfrac{8\times 7\times 6\times 5!}{5!}\\\\^8P_3=336[/tex]
So, there are 336 ways.
