Answer:
The initial value is;
y = 16
Step-by-step explanation:
Here, we want to get the initial value of y
Generally, for an exponential function,
we have the form as;
y = a•b^x
where the initial value is the value we have when x = 0
Looking at the given function, substituting x = 0
We have the function as;
y = 16(0.75)^0
y = 16 * 1
y = 16
So the initial value is 16

Find a quadratic equation whose roots are -3 and 5
Answer:
x² - 2x - 15 = 0Step-by-step explanation:
Roots:
x₁ = -3, x₂ = 5The equation:
(x - x₁)(x - x₂) = 0(x - (-3))(x - 5) = 0(x + 3)(x - 5) = 0x² + 3x - 5x - 15 = 0x² - 2x - 15 = 0Step-by-step explanation:
Let the roots be a and b
a=-3b=5To form a equation the formula is
[tex]\sf x^2-(a+b)x+ab[/tex]
[tex] \sf➡ {x}^{2} - ( - 3 + 5)x + ( - 3)5 \\ \sf \: ➡ {x}^{2} - 2x - 15 = 0[/tex]

Answer:
about 21.9 ft²
Step-by-step explanation:
area of a half circle = [tex]\frac{\pi r ^{2} }{2}[/tex]
so [tex]\frac{\pi 3^{2} }{2} = 14.13716694[/tex] ft²
are of a square is [tex]bh\\[/tex]
so 6 x 6 = 36 ft²
so the area of the figure would equal the area of the square minus the area of the half-circle
36 ft² - 14.13716694 ft² = 21.86283306 ft² ≈ 21.9 ft²

p=10
Find the area of the shaped region
Answer:
Assuming π is represented by 3.14, the correct answer is [tex]50.24m^2[/tex].
Step-by-step explanation:
Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is [tex]\pi r^2[/tex], where r is the radius of the circle. Since the radius of the shaded circle is [tex]4m[/tex], you can infer that the area of the shaded region would be [tex]4^2 * 3.14[/tex] = [tex]16*3.14[/tex] = [tex]50.24m^2[/tex].

1. Circle each relation that is a function.
{(1, 3), (1, 5), (2, 7), (3, 9), (4, 11)}
{(0, 0), ( 21, 21), ( 22, 22), ( 23, 23)}
{(5, 5), (5, 4), (5, 3), (5, 2)}
{(2, 5), (3, 5), (4, 5), (5, 5)}
Answer:
2 and 4
Step-by-step explanation:
A relation describe a function when for every x is associated one and only one y
1) is not a function because when x = 1 there are two y associated (3 and 5)
2) yes, for the definition of function
3) is not a function because when x = 5 there are four y associated ( 5, 4, 3, 2)
4) yes, because for every x there is only one y associated (is not important if is the same)

(PLEASE HELP) Find the product of
(x+4)(x2+7x).
Answer:
x³ + 11x² + 28x
Step-by-step explanation:
(x + 4)(x² + 7x)
Each term in the second factor is multiplied by each term in the forst factor, that is
x(x² + 7x) + 4(x² + 7x) ← distribute parenthesis
= x³ + 7x² + 4x² + 28x ← collect like terms
= x³ + 11x² + 28x

Answer:
The equation to find [tex]x[/tex] is [tex](5\cdot x - 2)^{\circ} + (2\cdot x -2)^{\circ} + x^{\circ} = 180^{\circ}[/tex].
The degree measure of each angle is: [tex]m\angle J = 113^{\circ}[/tex], [tex]m\angle K = 44^{\circ}[/tex] and [tex]m\angle L = 23^{\circ}[/tex].
Step-by-step explanation:
From Euclidean Geometry we remember that the sum of internal angles in triangles equals 180°. If we know that [tex]m\angle J = (5\cdot x -2)^{\circ}[/tex], [tex]m \angle K = (2\cdot x - 2)^{\circ}[/tex] and [tex]m\angle L = x^{\circ}[/tex], then we construct the following equation of the triangle JKL in function of [tex]x[/tex]:
[tex]m\angle J + m\angle K + m\angle L = 180^{\circ}[/tex] (1)
[tex](5\cdot x - 2)^{\circ} + (2\cdot x -2)^{\circ} + x^{\circ} = 180^{\circ}[/tex]
[tex]8\cdot x -4 = 180^{\circ}[/tex]
[tex]8\cdot x = 184[/tex]
[tex]x = 23[/tex]
Finally, the measure of each angle is, respectively:
[tex]m\angle J = (5\cdot x -2)^{\circ}[/tex]
[tex]m\angle J = 113^{\circ}[/tex]
[tex]m \angle K = (2\cdot x - 2)^{\circ}[/tex]
[tex]m\angle K = 44^{\circ}[/tex]
[tex]m\angle L = x^{\circ}[/tex]
[tex]m\angle L = 23^{\circ}[/tex]

Answer:
5. ∠1.
6. ∠3.
7. ∠1.
8. 180°.
note: wherever there is a ∠ symbol, it means "angle".
Step-by-step explanation:
5. An exterior angle of the triangle is ∠1.
6. The remote interior angles of the triangle to the exterior angle 1 are ∠2 and ∠3.
7. The sum of the measure of angles 2 and 3 is equal to the measure of ∠1.
8. The sum of the measure of angles 1 and 4 is 180°.
note: wherever there is a ∠ symbol, it means "angle".

Answer:
17). x² - 16x + 63 18). 6x² + 16x + 8
Step-by-step explanation:
17). (x - 9)(x - 7)
= x² - 7x -9x + 63
= x² - 16x + 63
18). (3x + 2)(2x + 4)
= 6x² + 12x + 4x + 8
= 6x² + 16x + 8
As an estimation we are told 5 miles is 8 km.
Convert 55 miles to km
Answer:
88 km.
Step-by-step explanation:
If 5 miles is 8 km,
55 miles is 88 km.
What you need to do is 55/5 = 11.
Then multiply that 11 to 8.
11 * 8 = 88.
Basically, if you are multiplying 5 by 11 to get 55, you need to multiply 8 by 11 to get 88.
