The value of sin2 Θ is in the 4th quadrant is -24/25
Explanation:
Given the expression of cosΘ= 3/5 with Θ in quadrant 4;
According to SOH, CAH TOA;
cosΘ= adjacent/hypotenuse
Get the opposite
5² = opp² + 3²
opp² = 25 - 9
opp² = 16
opp = 4
SinΘ = opp/hyp
SinΘ = 4/5
Sin2Θ = 2sinΘ cosΘ
Sin2Θ = 2(-4/5)(3/5)
Sin2Θ = -24/25
Hence the value of sin2Θ is in the 4th quadrant is -24/25

A jar contains n nickels and d dimes. There are 26 coins in the jar, and the total value of the coins is $1.90. How many nickels and how many dimes are in the jar?
Answers
Answer:
14 Dimes and 12 Nickels
Step-by-step explanation:
So you want to make 2 equations like this:
n+d=26
0.05n+0.10d=2
Now, use substitution and get d=26-n
plug that into the next equation and get
0.05n+0.10(26-n)=2
Distribute and combine like terms
0.05n+2.6-0.10n=2
2.6-0.05n=2
subtract 2.6 from both sides and you get
-0.05n=-0.6
Solve for n by dividing and you get
12 nickels.
Now, plug that into the first equation and you get
12+d=26
d=14

Chris is opening candy store. He is charging $4 for a small box of candy and then $1.25 for each additional box. What is the slope and y-intercept for this situation?
Answers
Answers:
Slope = 1.25
y intercept = 4
Explanation:
The slope is the rate of change. In this case, it's the price of getting an extra box.
The y intercept is the starting cost assuming that everyone has to get at least one small box of candy.

the first four terms are 2, 4, 6, and 8
Step-by-step explanation:
the y intercept becomes the first term. the for each value y increases by 2, this is the common difference.there are two ways you can get it. the by using equation of linear graphs y=mx+c and another by using the formula of AP Tn=a+(n-1)d.
both m(slope) and common difference(d) means the same thing.

If f(x) is an exponential function where f(1.5) = 7 and f(8.5) = 46, then find the value of f(14), to the nearest hundredth.
Answers
Answer:
[tex]f(14)=201.932[/tex]
Step-by-step explanation:
Set up a system of equations and solve for "b"
[tex]\left \{ {{46=ab^{8.5}} \atop {7=ab^{1.5}}} \right\\ \\\left \{ {{\frac{46}{b^{8.5}}=a } \atop {\frac{7}{b^{1.5}}=a} \right\\\\\frac{46}{b^{8.5}}=\frac{7}{b^{1.5}}\\ \\46b^{1.5}=7b^{8.5}\\\\46=7b^7\\\\\frac{46}{7}=b^7\\ \\b=1.308604899[/tex]
Determine the value of "a" using "b"
[tex]y=ab^x\\\\46=a(1.308604899)^{8.5}\\\\46=9.837224985a\\\\a=4.676115477[/tex]
Find f(14) using the new function
[tex]f(x)=4.676115477(1.308604899)^x\\\\f(14)=4.676115477(1.308604899)^{14}\\\\f(14)\approx201.932[/tex]

x = 6
y = 5.5
Step-by-step explanation:
Since the shapes are similar:
A = E and
C = G
60+8x = 108 subtract 60 from both sides
8x = 48 divide both sides by 8
x = 6
8y - 3x = 62 we know x is 6
8y - 3*6 = 62
8y - 18 = 62 subtract 18 from both sides
8y = 44 divide both sides by 8
y = 5.5

Step-by-step explanation:

So, both have been multiplied by 2.

~AH1807Answer: x 2
The answer is "x 2". This is because, as we see, 1 is then turned into 2. This is because 1 is multiplied by 2, which equals 2. 1 x 2 = 2. And 3 is turned into 6 through multiplication. 3 x 2 = 6. So we can see that the relationship between the quantities is "x 2".

There's a positive correlation between the amount of fertilizer a homeowner uses

Which statement is true?
The correlation is most likely a causation.
The correlation is most likely a coincidence.
The correlation is most likely due to a lurking variable.
Answers
Answer:
The correlation is most likely a causation
Step-by-step explanation:
Causation
A change in one variable causes a change in another variable
Coincidence
The two variables are not related at all, but correlate by chance.
Lurking variable
A variable that is not measured in the study (i.e. it's a third variable that is neither the explanatory nor the response variable)
As fertilizer directly affects plant growth, then the correlation is most likely a causation
8j + 5 = 61
Steps to solve
Answers
Answer:
j =7
Step-by-step explanation:
8j + 5 = 61
Subtract 5 from each side
8j + 5-5 = 61-5
8j = 56
Divide each side by 8
8j/8 = 56/8
j = 7
Answer:
J = 7
Step-by-step explanation:
8j + 5 = 61
8j = 61 - 5
8j = 56
8j ÷ 8 = 56 ÷ 8
j = 7

well, there are 3 feet per 1 yard, so we can say that the field is either
90 feet (30yd) by 48 feet
or
30 yards by 16 yards(48 feet)
90ft * 48ft = 4320 ft²
30yd * 16yd = 480 yd².
