Answer:

Tn = 12(-1/2)^n

Step-by-step explanation:

We have the nth term of a geometric sequence as

Tn = ar^n-1

a is the first term

r is the common ratio

n is term number

by dividing the second term by the first, we can have the common ratio

We have this as -6/12 or 3/-6 = -1/2

a the first term is 12

So we have the explicit formula as;

Tn = 12(-1/2)^n

Answer:

3x³ + x² + x + 1

= 3x³ - 3x² + 4x² - 4x + 5x - 5 + 6

= 3x²(x - 1) + 4x(x - 1) + 5(x - 1) + 6

= (x - 1)(3x² + 4x + 5) + 6

but 3x³ + x² + x + 1 = (x - 1).Q(x) + R

=> Q(x) = 3x² + 4x + 5

R = 6

Answer:

14

Step-by-step explanation:

a2+(48)2=

 502\,\,50^{2}502

Use the Pythagorean Theorem.

a2+2304=a^{2}+2304=a2+2304=

 2500\,\,25002500

Simplify.

−2304-2304\phantom{=}−2304=

 −2304\,\,-2304−2304

Subtract 2304 from both sides.

a2=a^{2}=a2=

 196\,\,196196

a2=\sqrt{a^{2}}=a2

​=

 ±196\,\,\pm\sqrt{196}±196

​

Square root both sides.

a=a=a=

 14\,\,1414

Simplify. Ignore negative root, as length must be positive.

Answer:

95°

Step-by-step explanation:

2x+108=180

2x=180-108

2x=72

x=72/2=36

m L H = x+59=36+59=95°

There are 6 numbers in a die.

So, theoretical probability of each no. = 1/6

P(1) = 7/42 = 1/6

P(2)= 6/42 =1/7

P(3) = 14/42= 1/3

P(4)= 4/42=2/21

P(5)= 6/42= 1/7

P(6)= 5/42

For no. 1 experimental probability of rolling the number the same as the theoretical probability

Answer:

Pretty sure 4.1 is an even number, 88° to be exact.

since your homework is quite much and kinda boring, the only thing you could offer me as motivation are brainliests. like in reposting the same sheet.

but this here for free: the of all three angles inside a triangle is 180 degrees.

half a turn of a full circle is 180 degrees, wich is important to calculate excercises 2 and 3 using subtraction.

for the first brainliest you can have 1-4

for the second 5-7 and for the third and fourth 8-9 and 10-11.

the whole sheet for a maybe-brainliest just isn't enough. it's like half an hour of grind work man

Answer:

(-4, 3)

Step-by-step explanation:

There are coordinate rules for reflection that really help me with these:

Reflection over x-axis -- (x, y) -> (x, -y)

Reflection over y-axis -- (x, y) -> (-x, y)

Reflection over y = x -- (x, y) -> (y, x)

Reflection over y = -x -- (x, y) -> (-y, -x)

Hope this helps :]

Answer:

C. 11/21

Step-by-step explanation:

Find the probability that he scores in general, by dividing 33 by 63:

33/63

Simplify this by dividing the numerator and denominator by 3:

= 11/21

So, the probability that he will score his next shot is 11/21

The correct answer is C. 11/21

Answer:

The binomial in expanded form is [tex](0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}[/tex].

Step-by-step explanation:

The Binomial Theorem states that a binomial of the form [tex](a + b)^{n}[/tex] can be expanded by using the following identity:

[tex](a + b)^{n} = \Sigma \limits^{n}_{k = 0}\,\frac{n!}{k!\cdot (n-k)!}\cdot a^{n-k}\cdot b^{k}[/tex] (1)

If we know that [tex]a = p = 0.3[/tex] and [tex]n = 5[/tex], then the expanded form of the binomial is:

[tex](p+q)^{n} = \frac{243}{100000} + 5\cdot \left(\frac{81}{10000} \right)\cdot q + 10\cdot \left(\frac{27}{1000})\cdot q^{2} + 10\cdot \left(\frac{9}{100} \right)\cdot q^{3} + 5\cdot \left(\frac{3}{10} \right)\cdot q^{4} + q^{5}[/tex]

[tex](0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}[/tex]

Step-by-step explanation:

Answer:

82°

Step-by-step explanation:

i. 8x +26 = angle 5 (corresponding angles)

ii. angle 5 = -9x + 179 ( vertically opposite angles)

so,

8x+26= -9x +179 (from i and ii)

or, 17x= 153

therefore, x= 9

now,

angle3 + 8x +26= 180° (linear pair)

angle 3 = 180°- 72-26

hence, angle 3= 82°

Answer:

<3=134.75

Step-by-step explanation:

8x+26=<4

Since angles 3 and 4 are supplementary, write an equation.

(8x+26)+<3=180

Subtract 26 from both sides

8x+<3=154

divide 8 to isolate the variable

x=19.25

`19.25+<3=154

<3=134.75 degrees

Sorry if this is wrong.

Assuming she is dividing into 1/2 lb blocks.  

15 of the 1/2 lb are given to the class.

Step-by-step explanation:

She can make 22 of the 1/2 lb blocks out of 11 lbs.  If she sets aside 7, then 22-7=15.  She has 15 of the 1/2lb blocks left to give to the class.

Answer: 20 years old

Step-by-step explanation: when Zoe was six years old, Lulu would have been 12 years old since Lulu's age is twice that of Zoe's. Since Zoe is now 10 years old, Lulu would have to be 20 years old since 10 multiplied by 2 equals 20.
