Answer:
191
Step-by-step explanation:
First, determine if the sequence is arithmetic or geometric.
If it is arithmetic, the difference between consecutive terms is constant.
If it is geometric, the ratio between consecutive terms is constant.
[tex]\sf 11 \underset{+4}{\longrightarrow} 15 \underset{+4}{\longrightarrow} 19[/tex]
As we add 4 to each term to get the next term, this is an arithmetic sequence with common difference of 4.
Arithmetic sequence
General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsGiven:
a = 11d = 4Substituting the given values into the formula to find an equation for the nth term:
[tex]\implies a_n=11+(n-1)4[/tex]
[tex]\implies a_n=4n+7[/tex]
Therefore, to find the 46th term, substitute n = 46 into the equation:
[tex]\implies a_{46}=4(46)+7=191[/tex]

Given cosθ= -[tex]\frac{7}{9}[/tex] and tanθ<0, find sin2θ
[tex] \sin {}^{2} (x) + {cos}^{2} (x) = 1[/tex]
[tex] {sin}^{2} (x) = 1 - {cos}^{2} (x)[/tex]
[tex] {sin}^{2} (x) = 1 - ({ \frac{ - 7}{9} })^{2} \\ [/tex]
[tex] {sin}^{2} (x) = 1 - \frac{49}{81} \\ [/tex]
[tex] {sin}^{2} (x) = \frac{81}{81} - \frac{49}{81} \\ [/tex]
[tex] {sin}^{2} (x) = \frac{32}{81} \\ [/tex]
[tex] \sin(x) = ± \sqrt{ \frac{32}{81} } \\ [/tex]
_____________________________________________
[tex] \tan(x) < 0 \: \: \: and \: \cos(x) < 0[/tex]
Thus :
[tex] \sin(x) > 0[/tex]
So we have :
[tex] \sin(x) = + \sqrt{ \frac{32}{81} } \\ [/tex]
[tex] \sin(x) = \frac{ \sqrt{16 \times 2} }{ \sqrt{9 \times 9} } \\ [/tex]
[tex] \sin(x) = \frac{4 \sqrt{2} }{9} \\ [/tex]
_____________________________________________
[tex] \sin(2x) = 2 \times \sin(x) \times \cos(x) [/tex]
[tex] \sin(2x) = 2 \times \frac{4 \sqrt{2} }{9} \times ( - \frac{7}{9} ) \\ [/tex]
[tex] \sin(2x) = - \frac{56 \sqrt{2} }{81} \\ [/tex]
Find the area of the shaded region. Express your answer in terms of \piπ and do not round any numbers.
Answer:
The strategy is to find out the total area and find the area of the 3 circles then subtract the sum of the circles' are from the total area
Total area = (length * width) = ( 3+6+9+12) * 18 = 540 sq. inch
3 Circles area = πr₁² + πr₂² + πr₃²
r₁= 12/2 = 6 in r₂ = 9/2 = 4.5 in r₃ = 6/2 = 3 inπr₁² + πr₂² + πr₃²
π(6²) + π(4.5)² + π(3)²
= 36π + 20.25π + 9π
= 65.25π
Shaded area = 540 - 64.25π = 335.011 sq. in

Answer:
A. This is a vertical angle set. As you can see, they are cut by the transversal and have the exact same interior angle, so it is a vertical angle.
B. Since these too are vertical angles, all you have to do is just put each expression on the sides of an equation like so:
5y-29=3y+19
Once you do this, you just need to simplify the equation by putting like terms together, and then you will find the solution for y, which is 24.
C. We know that the solution for y is 24, so we need to plug it into the equation to find, the angle, so if we do 3*24-19, we get 53, so we need to subtract that from 180 degrees, which is the total angle of the straight line, then we can get 127 degrees, which is what angles <7 and <8 are.

equation of the new function?
A. g(x) = x
O B. g(x) = 7x
x
O c. g(x) = x - 7
D. g(x) = x+7
awnser
The correct answer is C. f(x) = x - 7
Step-by-step explanation:
In order to find this, you simply need to know that vertical shifts can be added on to the end of parent equations as constants. Since this is a downward shift, we use a negative number.

The equation of the line which passes through the point (3, 7) and has a gradient of 3 is:
Answer:
y = mx + b, where m is gradient and b is y-intercept
y = 3
y = 3x + b
To find b use the coordinate (3, 7) to find b
7 = 3(3) + b
b = 7 - 9
b = -2
Therefore, the equation will be:
Therefore, the equation will be:y = 3x - 2

What is the exact value of the other root?
The exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]
How to express the solution?One of the root is given as:
[tex]x = -2 - \sqrt 6[/tex]
As a general rule, the solution to a quadratic equation is represented by:
[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
This means that the actual root of the given root is:
[tex]x = -2 \pm \sqrt 6[/tex]
Split the equation
[tex]x = -2 - \sqrt 6[/tex] and [tex]x = -2 + \sqrt 6[/tex]

Write the sequences equation for the table . Your equation should be in the form a(n)=man+b
Answer:
a(n) = 3.25n + 1.25Step-by-step explanation:
7.75-4,5 = 3.25
11-7.75 = 3.25
14.25-11 =3.25
17.5-14,25 = 3.25
It’s clear that this is an arithmetic sequence with common difference of 3.25
The equation form of such sequence is a(n) = a×n + b ,where ‘a’ is the common difference.
Then
a = 3.25
The first term a₁ = 4.5
On the other hand, a₁ = 3.25 ×(1) + b
Then
4.5 = 3.25 ×(1) + b
Then
b = 4.5 - 3.25 = 1.25
Conclusion:
a(n) = 3.25n + 1.25
Suppose you write the numbers 1 to 10 on separate index cards. You randomly choose one card, place it back in the set, and then randomly choose another card. What is the probability that the first card you choose is the number 1 or the second card you choose is the number 2?.
Answer:
1/100
Step-by-step explanation:
From 1 to 10 there are 10 numbers, so the fraction would be:
# / 10
Since you are putting the cards back into the deck, the denominator will never change.
The chances of getting " 1 " are 1 / 10.
And the chances of getting " 2 " are also 1 / 10
To find the odds of getting one-after-the-other, you multiply these 2 chances.
( 1 / 10 ) x ( 1 / 10 ) = ( 1 / 100 )
There is a 1 / 100 chance that you will draw 1, then 2 if you put the cards back after drawing.

Answer:
-1/2x -(5 23/42)y
Step-by-step explanation:
We assume you want to simplify the expression ...
(2 3/10)x -(5/7)y -(4 5/6)y -(2 4/5)x
__
The mixed numbers and fractions are combined in the usual way. A common denominator needs to be found for the addition or subtraction to take place.
= x(2 3/10 -2 4/5) -y(5/7 +4 5/6)
= x(23/10 -28/10) -y(30/42 +4 35/42)
= x(-5/10) -y(4 65/42)

Answer:
Step-by-step explanation:
a, First arrange the data in ascending order:
77 79 80 81 84 84 86 88 92 95 <-- ten numbers.
Mean = sum of the numbers / 10
= 846/10
= 84.6.
The median is the middle number in the ordered list, or if there are an even number of values, the mean of the 2 middle numbers. There are 10 numbers here, so the median = (84+84)/2 = 84
Median = 84.
The mode is the value that occurs most. Here we have 2 84's so
Mode = 84.
Parts b to d are done in the same way as for the above, note if there is no mode write None.
For the stem leaf data first write out individual vales and then proceed as in a).

(3) 235
(2) 485
(4) 415
The angle which is coterminal with the angle 125 degree when drawn in standard position is -235 degrees. Option A is correct.
What is the coterminal or terminal side of an angle?The terminal side of an angle is the rotated side of the initial side around a point to form an angle. This rotation can be clockwise or counter clock wise.
The angle given in the problem is,
θ=125°
The angle which is coterminal of this angle is,
θ=125°-360°
θ=-235°

A quantity with an initial value of 870 decays continuously at a rate of 0.75% per day.
what is the value of the quantity after 10 weeks, to the nearest hundredth?
The function of the exponential decay will be y = 870(0.75)ˣ. Then the value of the quantity after 10 weeks will be 49.
What is exponential growth or decay function?Consider the function:
y = a(1 ± r)ˣ
where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction.
If there is a negative sign, then there is exponential decay happening by r fraction.
A quantity with an initial value of 870 decays continuously at a rate of 0.75% per day.
Then the function is given as
y = 870(0.75)ˣ
Then the value of the quantity after 10 weeks will be
y = 870(0.75)¹⁰
