Identify the 42nd term of an arithmetic sequence where a_1=-12 and a_27=66
Wittaler [7]

Answer:

a₄₂ = 107

Step-by-step explanation:

The nth term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₂₇ = 66 , then

a₁ + 26d = 66 , that is

- 12 + 26d = 66 ( add 12 to both sides )

26d = 78 ( divide both sides by 26 )

d = 3

Then

a₄₂ = - 16 + (41 × 3) = - 12 + 123 = 111

Answer:

92 cm

Step by step explanation:

first: you divide the rectangle into two right angled triangles using the diagonal

secondly:

you use pythagoras theorem to find the width of the rectangle

110²= 60²+ w²

w²= 110²- 60²

w²= 12100- 3600

w²= 8500

w= 92.195

w= 92 cm

Boxes that are 12 inches tall are being stacked next to boxes that are 18 inches tall. What is the shortest height qt which the
motikmotik

Answer:

The shortest height is 36 inches

Step-by-step explanation:

Here in this question, we want to know the shortest height with which boxes of 12 inches tall staked will be the same height with which boxes of 18 inches staked beside it

This is a question that has to do with multiples; In other words, we are simply looking for the lowest common multiple of 12 and 18;

The multiples of both are as follows;

12 - 12, 24,36,48,60•••••

18-18,36,54,72••••••

We can see that at the point 36, both have their first multiple match

So we can say that the lowest common multiple of 18 and 12 is 36

If tan 0=3/4 find sin0
bija089 [108]

Answer:

sin O = \frac{3}{5}

Step-by-step explanation:

given tan O = \frac{3}{4} = \frac{opposite}{adjacent}

Then this is a right triangle with legs 3 and 4

Using Pythagoras' identity then the hypotenuse (h ) is

h = \sqrt{3^2+4^2} = \sqrt{25} = 5, hence

sin O = \frac{opposite}{hypotenuse} = \frac{3}{5}

Please help me with this math problem!! Will give brainliest!! :)
lora16 [44]

Answer:

2x^3-3x^2-10x+15\\

Step-by-step explanation:

To find (fg)(x), we have to look at f(x) and g(x) and multiply the two quantities together. We are already given the two quantities individually so all that is left is the multiplication:

(fg)(x)=(-2x+3)(5-x^2)=-10x+2x^3+15-3x^2\\

If we reorder the terms to go from highest degree to lowest, we get our final answer to be the following:

2x^3-3x^2-10x+15
