Answer:
m = 5
a = -3
b = -15
Step-by-step explanation:
(m - 2) = 3 for x^2
(2a + 3) = - (m - 2) = (2 - m) for x^1
(b + 6) = (2a - 3) for x^0

Which situations can be represented by an exponential function?
Select each correct answer.
Every year, the number of online video subscriptions increases by 3 times what is was the previous year.
In a structure made of bricks, each row has 10 more bricks than the previous row.
The value of a vehicle decreases by 11% each year.
A dentist's office accepts 15 new patients each month.
9514 1404 393
Answer:
(a) subscriptions
(c) vehicle value
Step-by-step explanation:
Exponential functions are used to describe situations where the amount of change is proportional to the amount.
If the amount of change is a constant, then the function is linear.
A. video subscribers change by an amount proportional to their number, so is an exponential function.
B. the change in number of bricks in a row is a constant, so the function is a linear function.
C. The amount of change is proportional to the value, so the function is an exponential function.
D. The change in patient count is a constant, so the function is a linear function.
Solve for n:
1-5|n-9|=-74
I need answer by 12:10, please help!!!
Answer:
[tex]n=-6, 24[/tex]
Step-by-step explanation:
We are given:
[tex]1-5|n-9|=-74[/tex]
Subtract 1 from both sides:
[tex]-5|n-9|=-75[/tex]
Divide both sides by -5:
[tex]|n-9|=15[/tex]
By definition of absolute value:
[tex](n-9)=15\text{ or } -(n-9)=15[/tex]
Solve for each case:
[tex]n=24\text{ or } n=-15+9=-6[/tex]
Therefore, our two solutions are:
[tex]n=-6, 24[/tex]

Convert the following quadratic equation to vertex form. 2) 3x2 - 12x - 5
Answer:
2*12x-5
Step-by-step explanation:
In geometry, a vertex form is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices. For example, a square has four corners, each is called a vertex.
The mid point of a given line segment must lie on the given line segment

Answer:
28 litres of mango juice will be required
Step-by-step explanation:
11). b. Internal dimensions of the rectangular prism are,
Length = 40 cm
Width = 20 cm
Height = 35 cm
Volume of the rectangular prism = Length × Width × Height
= 40 × 20 × 35
= 28000 cm³
Since, 1 cm³ = 1 mL
Therefore, 28000 cm³ = 28000 mL
Since, 1000 mL = 1 L
28000 mL = 28 L
Therefore, to fill this jar 28 L of orange juice will be required.
Find the number of terms and the degree of this polynomial. -9
[tex]9 {r}^{9} [/tex]
Number of terms: Degree:
Answers:
Number of terms: 1Degree: 9===============================================
Explanation:
This is consider a monomial since we only have one term. Terms are separated by a plus sign, so something like 5x^2+10x has two terms.
The degree of a polynomial is the largest exponent when dealing with single variables. In the case of 9r^9, the largest exponent is 9, so the degree is 9. Going back to an example like 5x^2+10x, the largest exponent is 2 so this is the degree of this example.

Answer:
x = 16
Step-by-step explanation:
For the triangle to be isosceles then AB = CB , that is
5x - 9 = 4x + 7 ( subtract 4x from both sides )
x - 9 = 7 ( add 9 to both sides )
x = 16

Exponents work the same way on bases that are _[blank A]_ as they do on bases that are numbers.
When a variable has an exponent, the exponent tells you how many times the variable is _[blank B]_ by itself.
In order to make a negative exponent positive, you must take the _[blank C]_ of the base.
A variable raised to the power of _[blank D]_ is always equal to 1.
Match each blank with the correct item that fills in that blank.

Explain how you can use ratios of the side lengths to find the angle measures of the acute angles in a right triangle.
Answer:
The answer is below
Step-by-step explanation:
Triangles are polygons with three sides and three angles. Types of triangles are isosceles, equilateral, scalene and right angled triangles.
Trigonometric identities are equations that uses trigonometric functions to show the relationship between the angles in a right angle triangle and the sides of the right angled triangle.
If θ be an acute angle in a right angled triangle, hyp. is the hypotenuse side of the angle, opp. is the opposite side to the angle and adj. is the adjacent side to the angle, then:
sinθ = opp. / hyp.v; cosθ = adj. / hyp. ; tanθ = opp. / adj.

Select the correct answer. What is the value of a in the function’s equation?
Answer:
[tex]a = -2[/tex]
Step-by-step explanation:
Given
The attached function (graph)
Required
Find a
The given function is quadratic and will be solved using:
[tex]y = ax^2 + bx + c[/tex]
From the attachment:
[tex](x,y) = (-3,4)[/tex]
[tex](x,y) = (-2,2)[/tex]
[tex](x,y) = (-4,2)[/tex]
Substitute these values in [tex]y = ax^2 + bx + c[/tex]
For: [tex](x,y) = (-3,4)[/tex]
[tex]4 = a(-3)^2 + b(-3) + c[/tex]
[tex]4 = 9a -3b + c[/tex]
For: [tex](x,y) = (-2,2)[/tex]
[tex]2 = a(-2)^2 + b(-2) + c[/tex]
[tex]2 = 4a -2b + c[/tex]
For: [tex](x,y) = (-4,2)[/tex]
[tex]2 = a(-4)^2 + b(-4) + c[/tex]
[tex]2 = 16a -4b + c[/tex]
So, we have:
[tex]4 = 9a -3b + c[/tex] --- (1)
[tex]2 = 4a -2b + c[/tex] ---- (2)
[tex]2 = 16a -4b + c[/tex] --- (3)
Make c the subject in (1)
[tex]c = 4 - 9a + 3b[/tex]
Substitute [tex]c = 4 - 9a + 3b[/tex] in (2) and (3)
[tex]2 = 4a -2b + c[/tex]
[tex]2 = 4a -2b + 4 - 9a + 3b[/tex]
Collect Like Terms
[tex]-4 + 2 = 4a - 9a-2b + 3b[/tex]
[tex]-2 = - 5a+b[/tex] --- (4)
[tex]2 = 16a -4b + c[/tex]
[tex]2 = 16a - 4b + 4 - 9a + 3b[/tex]
Collect Like Terms
[tex]2 -4 = 16a - 9a + 3b- 4b[/tex]
[tex]-2 = 7a -b[/tex] --- (5)
Add 4 and 5
[tex]-2 = - 5a+b[/tex]
[tex]-2 = 7a -b[/tex]
--------------------------
[tex]-2 - 2 = -5a + 7a +b - b[/tex]
[tex]-4 = 2a[/tex]
Divide through by 2
[tex]-2 = a[/tex]
[tex]a = -2[/tex]
