Find the distance between the two points in simplest radical form (3, 8) and (5, - 1)
Answer:
[tex]d = \sqrt{85}[/tex]
Step-by-step explanation:
Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(5-3)^2+(-1-8)^2}[/tex]
[tex]d = \sqrt{(2)^2+(-9)^2}[/tex]
[tex]d = \sqrt{4+81}[/tex]

what is the measure of angle dgv?
enter your answer in the box
The measure of angle MBT as shown in the diagram is 28 degrees.
What is an angle?An angle is formed from the intersection of two or more lines. Types of angles are obtuse, acute and right angled.
From the diagram:
∠MBN = ∠MBT
17x - 6 = 5x + 18
x = 2
∠MBT = 5(2) + 18 = 28 degrees
The measure of angle MBT as shown in the diagram is 28 degrees.

MQ = 2x+2
QO= 3x-10
find x
(it’s a rhombus)
Answer:
2x+2=3x-10
2+10=3x-2x
x= 12
Answer:
x = 12
Step-by-step explanation:
The diagonals PN and MO are perpendicular bisectors of each other, thus
QO = MQ , substitute values
3x - 10 = 2x + 2 ( subtract 2x from both sides )
x - 10 = 2 ( add 10 to both sides )
x = 12

Write an equation with a slope of -5 and a y-intercept of O
Answer:
[tex]y=-5x+0[/tex]
Step-by-step explanation:
We know that slope intercept form is:
[tex]y=mx+b[/tex]
And our slope is -5, and the variable we use for slope is m:
[tex]m=-5[/tex]
Our new equation becomes:
[tex]y=-5x+???[/tex]
And our y-intercept is 0, and the letter we use to express our y-intercept is b:
[tex]b=0[/tex]
Our new equation is:
[tex]y=-5x+0[/tex]
Hence, the correct answer is [tex]y=-5x+0[/tex]
Given that x= 7.4 m and θ = 23°, work out AC rounded to 3 SF.
Answer:
18.939
Step-by-step explanation:
Use SOH CAH TOA to find sin(23) = 7.4/x. Convert it to x(sin23) = 7.4. Divide both sides by sin23 to get x=18.939
Hey there!
[tex]\overline{AB} = 7.4m[/tex]
[tex]\overline{ACB} = 23°[/tex]
[tex] Sin(ACB) = \frac{\overline{AB}}{\overline{AC}}[/tex]
[tex] Sin(23°) = \frac{7.4}{\overline{AC}}[/tex]
[tex]\overline{AC}=18.939m[/tex]

Bob is doing a quality test on machine bots , he tested 24 bolts that he randomly found that 5 were defective. Based on bob’s results what is the expected number of bolts that will be defective if he tests 840 bolts? A.139 B. 145 C. 175 D. 211
The expected number of defective bolts are obtained as 175. The correct option is (C).
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lie in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
The total number of bolts tested are 24.
And, the number of defective bolts are 5.
Then, the probability of defective bolts is given as,
P(defective bolts) = 5/24
Now, the expected number of bolts can be found as,
Expected number = P(defective bolts) × Total number of bolts tested
⇒ 5/24 × 850 = 175
Hence, the expected number of bolts that will be defective is given as 175.

Two angles are supplementary. The measure of the larger angle is 12 less than 3 times the measure of the smaller angle.Find the measure of each angle
Answer:
48 , 132
Step-by-step explanation:
Let smaller angle = x
Larger angle = 3x - 12
x & (3x - 12) are supplementary
So, x + 3x - 12 = 180°
4x - 12 = 180
4x = 180 +12
4x = 192
x = 192/4
x = 48°
Larger angle = 3*48 - 12 = 144 - 12 = 132
Answer: The measure of the smaller angle is 48,and the larger angle is 132.

Which statement is true?
A.
The function is an even function because its graph is symmetric about the origin.
B.
The function is an odd function because .
C.
The function is an even function because .
D.
The function is an odd function because its graph is symmetric about the y-axis.
Answer:
B. The function f(x) = tan(x) is an odd function because f(-x) = -f(x)
Step-by-step explanation:
The function f(x) = tan(x) is odd as [tex]f(-x) = -f(x)[/tex] so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.
What are functions?The function is a relation used to determine a value f(x) for a given x using an expression in x.
What are even functions?An even function is when f(x) = f(-x). It is symmetric along the y-axis.
What are odd functions?An odd function is when f(-x) = -f(x). It is symmetric along the x-axis.
How do we solve the given question?We are dealing with the function f(x) = tan(x).
We calculate f(-x) = tan(-x) = -tan(x) = -f(x).
∴ The function f(x) = tan(x) is an odd function, and odd functions are symmetric about the origin.
∴ The function f(x) = tan(x) is odd as [tex]f(-x) = -f(x)[/tex] so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.
