D. 1 unit
Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The two points are C(2,-1) and D(5,3). Using the distance formula, we get
[tex]CD=\sqrt{(5-2)^2+(3-(-1))^2}[/tex]
[tex]CD=\sqrt{(3)^2+(3+1)^2}[/tex]
[tex]CD=\sqrt{(3)^2+4^2}[/tex]
On further simplification, we get
[tex]CD=\sqrt{9+16}[/tex]
[tex]CD=\sqrt{25}[/tex]
[tex]CD=5[/tex]
The distance from point C to D is 5 units. Therefore, the correct option is A.

State the amplitude and period of f(x) = 3cos9/5t
Answer:
The amplitude is 3 and the period is 10π/9.
Step-by-step explanation:
The standard cosine function is in the form:
[tex]y=a\cos(b(x-c))+d[/tex]
Where |a| is the amplitude, 2π/b is the period, c is the phase shift, and d is the vertical shift.
We have the function:
[tex]f(x)=\displaystyle 3\cos\frac{9}{5}t[/tex]
We can rewrite this as:
[tex]\displaystyle f(x)=(3)\cos\left(\frac{9}{5}\left(t-0\right)\right)-(0)[/tex]
Therefore, a = 3, b = 9/5, c = 0, and d = 0.
Hence, our amplitude is |3| = 3.
Our period will be:
[tex]\displaystyle \text{Period}=\frac{2\pi}{9/5}=2\pi \cdot \frac{5}{9}=\frac{10\pi}{9}[/tex]

A-
12
20
Answer:
x = 40
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
8(8 + x) = 12(12 + 20)
8(8 + x) = 12 × 32 = 384 ( divide both sides by 8 )
8 + x = 48 ( subtract 8 from both sides )
x = 40

p. s x= 110
y=120
Step-by-step explanation:
Let's take the blank space between y° and 40° as n°. Then let's solve angle AFC, and remember x is given, 110°.
x°+ n°+ 50° = 180°
110°+50°+n°=180°
160°+n° =180°
n = 180° - 160°
n = 20°
Remember that angle y, angle 40° and angle n are on a straight line, which means they add up to 180°. So
y + n°+ 40°=180°
y +20° +40° = 180°
y+ 60° =180°
y = 180° - 60°
y = 120°

What is the value of A for the exponential function in the graph represented in the form of f(x) = a(bx)?
Answer:
a = 3
Step-by-step explanation:
f(x) = a(bˣ)
At x = 0
f(0) = a(b⁰)
f(0) = a(1)
f(0) = a
From the graph
f(0) = 3
Therefor
a = 3

Describe and correct the error in determining which type of function the table represents.
Answer:
"Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."
Step-by-step explanation:
In reality, the table represents an exponential function instead of a linear function, since values on domain change arithmetically at constant rate, whereas values on range change geometrically at constant rate.
Correct phrase may be: "Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."

Write the other side of this equation so it's true for no values of x: }(6x - 10) - x =
Answer:
(6x - 10) - x = 5(x - 2)
Step-by-step explanation:
6x - 10 - x
5x - 10
5x - 10 = 5(x - 2)
5x - 10 = 5x - 10
5x - 10 ÷ 5 = 5x - 10 ÷ 5
x - 2 = x - 2
No solution.
x - 2 + 2 = x - 2 + 2
x = x

At the beginning of spring, Bilquis planted a small sunflower in her backyard. When it was first planted, the sunflower was 10 inches tall. The sunflower then began to grow at a rate of 0.5 inches per week. How tall would the sunflower be after 8 weeks? How tall would the sunflower be after w weeks?
Height After 8 weeks: ?
Height After w weeks: ?
Answer:
Height After 8 weeks: 14 inches
Height after w weeks: y=0.5w+10
Step-by-step explanation:
The equation of the sunflower is y=0.5x+10.
Height after 8 weeks: y=0.5(8)+10
y=4+10
y=14
Height After 8 weeks: 14 inches
Height after w weeks: y=0.5w+10

A line passes through the points (2,4) and (5,6).
Select Yes or No to tell whether each equation describes this line.
y−6=3/2(x+5) Yes No
y−4=2/3(x−2) Yes No
y−4=3/2(x+2) Yes No
y−6=2/3(x−5) Yes No
Answers:
NoYesNoYes============================================================
Explanation:
Let's use the slope formula to get
m = (y2-y1)/(x2-x1)
m = (6-4)/(5-2)
m = 2/3
The slope of the line is 2/3.
We can see that the responses for choices 1 and 3 are "no" because they involve a slope of 3/2.
-------------
Recall that y-y1 = m(x-x1) represents the point slope form. The m is the slope and (x1,y1) is the point the line goes through.
If we plugged the point (x1,y1) = (2,4) , along with the slope m = 2/3, then we'll get to what choice 2 is saying
If we tried the other point (5,6), and kept m the same, then we'd get to choice 4.
That makes choices 2 and 4 "yes" responses.

what is the value of X
Answer:
X=20
Step-by-step explanation:
Verticals angles have same degree.
3x=x+40
x=20
Answer:
The value of [tex]x[/tex] would be 20°.
Step-by-step explanation:
Since vertical angles are equivalent, and ∠SRT and ∠VRW are vertical angles, you can create the equation [tex]3x = x + 40[/tex] to solve for [tex]x[/tex]. [tex]3x = x+40[/tex] ⇒ [tex]2x = 40[/tex] ⇒ [tex]x=20[/tex]°, so that would be the correct answer.

Carlos is mailing packages. Each small package costs him $2.40 to send. Each large package costs him $2.90. How much will it cost him to send 1 small package and 3 large packages?
Answer:
$11.10
Step-by-step explanation:
1 small package = $2.40
1 large package = $2.90
1 small package + 3 large packages.
2.40 + (3 × 2.90)
=2.40 + 8.70
=11.1
Answer:
$11.10
Step-by-step explanation:
This problem can be modeled by 2.4x+2.9y=c
x=small packages
y=large packages
c=total cost
By plugging in the values you get 2.4(1)+2.9(3)=c
2.4+8.7=c
c=11.1
Therefore the total cost is $11.10
