(13 x 9 / 3) + 65 - 30 = 74

So,

13 * 9/3 + 65 - 30 = x

Use PEMDAS (ParenthesesExponentMultiplication/DivisionAddition/Subtraction)

117/3 + 65 - 30 = x
39 + 65 - 30 = x
104 - 30 = x

74 = x

There are 74 oranges in the end.

Answer:

Step-by-step explanation:

We have

$- 4 \sin(7t + 3)$

Here the value of a is always positive because distance is positive

$| - 4| = 4$

Next, we factor out 7 to get our period

$- 4 \sin(7(t + \frac{3}{7} ) )$

So our period is

$\frac{2\pi}{7}$

Next, our phase shift we set the inner parenthesis equal to 0.

$t + \frac{3}{7} = 0$

$t = - \frac{3}{7}$

So our phase shift is -3/7

Answer:

a true

b false

c. false

d. true

e. false

f. true

Step-by-step explanation:

The function is y =35+8x where x is the number of items sold and y is the earnings

To determine if the point is on the graph substitute the point in and see if it is true

a (7,91)

91 = 35+ 8(7)

91 = 35+ 56

91 = 91 true

b(11, 121)

121 = 35+ 8(11)

121 = 35+ 88

121 = 123 false

c. (9, 110)

110 = 35+ 8(9)

110 = 35+ 72

110 = 107 false

d. (4,67)

67 = 35+ 8(4)

67 = 35+ 32

67 = 67 true

e. (5,72)

72 = 35+ 8(5)

72 = 35+ 40

72 = 75 false

f. (3, 59)

59 = 35+ 8(3)

59 = 35+ 24

59 = 59 true

What is the sum of the first 50 terms of the series 2 + 17 + 32 + 47+ ...?

Alex

Answer:

$\huge\boxed{18,475}$

Step-by-step explanation:

The terms of this sum make the arithmetic sequence.

The fomula of a sum of <em>n</em> terms of an arithmetic sequence:

$S_n=\dfrac{[2a_1+(n-1)d]\cdot n}{2}$

We have

$a_1=2\\d=17-2=32-12=47-32=15\\n=50$

Substitute:

$S_{50}=\dfrac{[2\cdot2+(50-1)\cdot15]\cdot50}{2}=(4+49\cdot15)\cdot25=(4+735)\cdot25\\\\=739\cdot25=18,475$
