Answer:
cos(O) = 39 / 89
Step-by-step explanation:
Given:
ΔOPQ, where
∠Q=90°
PO = 89
OQ = 39
QP = 80
cosine of ∠O?
cos(O) = Adjacent / Hypotenuse
cos(O) = 39 / 89
Answer:
Solution given:
we have
<Q=90°
OP=hypotenuse [h]=89
base[b]=QP=39
perpendicular [p]=OQ=80
we have
cosecant <P=h/p=OP/OQ=89/80

Answer: Just use a calculator.
Step-by-step explanation:
There are 40 more pennies than nickels.
Find a combination that meets all 3 criteria:
*
There are 240 coins in the jar (only pennies, nickels, and
dimes)
* There are twice as many dimes as nickels.
* There are 40 more pennies than nickels.
*
Answer:
50 Nickels, 90 pennys, 100 dimes
Step-by-step explanation:
x = Nickels
x+40+x+x2=240
Add similar elements x+2x+x=4x
4x+40=240
Subtract 40 both sides
4x+40-40=240-40
4x =200
Divide Both sides by 4
4x/4 = 200/4
x=50

If (x,83) is a solution to the equation 2y=1/2(98x+38), find x.
Answer:
X= 2y/49 - 19/49
Answer:
because (x; 83) is a solution to the equation
2y=1/2(98x+38)
=> 2.83 = 1/2(98x + 38)
<=> 4.83 = 98x + 38
<=> 332 = 98x + 38
<=> 98x = 294
<=> x = 3

Use the graph of the function f(x) to answer each question. Use ∞ , -∞ or DNE where appropriate. Explain if DNE.
(I will give 60 additional points and a brainliest if answered properly, thank you so much) WILL BAN IF AN ABSURD ANSWER!!!
Answer:
(a) f(0) = 1
(b) f(3) = 5 (I'm not sure about this one, it's either this or undefined)
(c) f(-2) = 3
(d) [tex]\lim_{x\to -3^+} f(x)=1[/tex]
(e) [tex]\lim_{x \to -2} f(x)=1[/tex]
(f) [tex]\lim_{x \to 1^-} f(x)=2[/tex]
(g) [tex]\lim_{x \to 1} f(x)=[/tex] DNE, because the limit of x--> 1 from the left is 2, and the limit from the right is 1. Because they don't approach the same value from both sides, the limit doesn't exist.

(1 point) Question 7 options: 1) It is symmetric and has no gaps. 2) It is not symmetric and has a peak at $5.00. 3) It is a cluster from $1.00 to $5.00 and has gaps. 4) It is a cluster from $1.00 to $5.00 and has a peak at $5.00.
Answer:
A. It is symmetric and has no gaps.
Step-by-step explanation:
Given
See attachment for dot plot
Required
Select the true statement
From the attached plot, we can see that
The plot is bell shaped (by tracing the number of dots on each dataset) There is no gap between each dataset (from 4 to 7)Since (1) all bell shaped distribution are symmetric and (2) there is no gap between the dataset, then (a) is correct.

height of the coin?
A 6.25 meters
B. 12 meters
C. 14 meters
D. 14.45 meters
HELPPPPPPP
Answer:
D
Step-by-step explanation:
Differentiate the function and set it to zero:
f'(x) = -10x + 13
0 = -10x + 13
x = 1.3 seconds
Plug the x value into f(x):
f(1.3) = -5(1.3)^2 + 13(1.3) + 6 = 14.45 meters
16 girls and 14 boys put their names in a bag. One name is drawn from the bag. What is the probability that a boy's name will be pulled
Answer: [tex]\dfrac{7}{15}[/tex]
Step-by-step explanation:
Given
There are 16 girls and 14 boys
The favorable chances that a boy name comes up are 14
Probability is given by the ratio of favorable chances to the total chances
So, the probability that a boy's name will be pulled is
[tex]\Rightarrow P=\dfrac{14}{14+16}\\\\\Rightarrow P=\dfrac{14}{30}\\\\\Rightarrow P=\dfrac{7}{15}[/tex]

Step-by-step explanation:
Angle Introduction - The figure formed by the two line segments QR and QP from the common point Q is an angle. Angle Components - Segments QR and QP are called the sides or arms of the angle. The common point Q is called the vertex of the angle.
Find the IQR (interquartile range).
19, 21, 18, 17, 18, 22,46
Answer:
4.
Step-by-step explanation:
Step 1: Formula.
[tex]IQR=Q3-Q1[/tex]
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 2: Explain/define.
The interquartile range is the difference between quartile 3 and quartile 1.Quartile 1 is the median of the upper half of a data set.Quartile 3 is the median of the lower half of a data set.The median is the 'middle value.'--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 3: Order/arrange.
In order to find the median, you must first put the numbers in numerical order.
19, 21, 18, 17, 18, 22, 46
↓
17, 18, 18, 19, 21, 22, 46
The lower half of the data set, not including the median of the whole data set, is 17, 18, and 18.
The upper half of the data set is 21, 22, and 46.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 4: Solve.
17, 18, 1821, 22, 36Next, we find the medians of both sets.
The median of the lower half is 18 (Q1).
The median of the upper half is 22 (Q3).
Lastly, we subtract Q3 from Q1.
[tex]22-18=4.[/tex]
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Step 5: Conclude.
I, therefore, believe the interquartile range of this data set is 4.

Answer: b=11
Step-by-step explanation: If you try out all of the possible values, right away you get the first answer. Substitute 11 for be and you get 3(11)+1 which is 33+1 which is 34. Then do 114+32+34 which is equal to 180 degrees and all of the angles of a triangle have to be equal to 180 degrees. Hope this helps.
