Answer:
21.8 cm
Step-by-step explanation:
[tex] \\ 180 - 75 - 31.8 = 37.2 \\ \frac{ \sin(75) }{22} = \frac{ \sin(31.8) }{12} = \frac{ \sin(73.2) }{a} \\ a = \frac{22 \times \sin(73.2) }{ \sin(75) } = \\ a = \frac{21.06}{0.9659} = 21.8[/tex]

Find the mode 24,22,46,23,20,25,24
Answers
Answer:
24
Step-by-step explanation:
We are given a strand of numbers and are asked to find the mode.
To find mode, we have to see which number appears the most within the number strand, let's start with ordering the numbers from least to greatest.
20, 22, 23, 24, 24, 25, 46
Looking at the strand we see that 24 appears the most, therefore 24 is the mode.
Answer:
24
Step-by-step explanation:
Put the numbers in order.
20, 22, 23, 24, 24, 25, 46
Count how many of each number.
20
22
23
24, 24
25
46
The number that appeared the most is the mode.
24 appeared twice and the other numbers appeared only once.

8.7(what she put on during the six months)+ 15.9 (her weight now)= 24.6

Write an exponential function in the form y=ab^x that goes through points (0,6) and (5, 6144)
Answers
Given:
An exponential function goes through points (0,6) and (5, 6144).
To find:
The exponential function.
Solution:
The general form of an exponential function is
[tex]y=ab^x[/tex] ...(i)
It goes through points (0,6) and (5, 6144). It means the equation must be satisfied by these two points.
Putting x=0 and y=6, we get
[tex]6=ab^0[/tex]
[tex]6=a[/tex]
Putting a=6, x=5 and y=6144, we get
[tex]6144=6b^5[/tex]
[tex]\dfrac{6144}{6}=b^5[/tex]
[tex]1024=b^5[/tex]
Taking 5th root on both sides, we get
[tex]\sqrt[5]{1024}=b[/tex]
[tex]4=b[/tex]
Putting a=6 and b=4, we get
[tex]y=6(4)^x[/tex]
Therefore, the required exponential function is [tex]y=6(4)^x[/tex].
what is m CDJ?
please help me I'm super confused.
Answers
Answer:
34 degrees.
Step-by-step explanation:
Assuming AK is a straight line and being shown angle JDK is right and 90 degrees it can be stated that 4x + (3x-8) = 90 degrees.
Drop the parentheses and get 7x - 8 = 90.
Add 8 to both sides 7x = 98.
Divide both sides by 7, x = 14.
Plug that x value into (3x-8), [3(14)-8] = 34 degrees.
Answer:
34 degrees
Step-by-step explanation:
So, because mJDK and mJDA lie on a line, they must be supplementary, and since mJDK is 90 degrees, mJDA must be too. So, you know that the combination of mADC and mCDJ must be 90 degrees. 4x+3x-8=90 simplified is 7x=98, which says that x is equal to 14. So you plug in the values for 3x-8, and voila! mCDJ is 34!
