The first term of an arithmetic sequence is six. The fifth term of the sequence is -14. th Write a rule that can be used to find the nth term.
Answers
Answer:
[tex]a_{n} = 11 - 5n[/tex]
Step-by-step explanation:
use the formula
[tex]a_{n} = a_{1} + (n - 1)d[/tex]
-14 = 6 + (5 - 1)d
-14 = 6 + 4d
-20 = 4d
d = -5
[tex]a_{n} = 6 + (n - 1)(-5) = 6 - 5n + 5 = 11 - 5n[/tex]

find the surface area of the cube below.
Answers
Answer:
150
Step-by-step explanation:
surface area =6a^2
= 6(5^2)
= 6×25
=150
Answer:
150 cm²
Step-by-step explanation:
So, firstly we must understand what does total surface area means (T.S.A)
We intuitively know that, it means,
Area of 6 EQUAL faces.
So,
Edge of the cube = 5 cm
Area of 1 face= 5 × 5= 25 cm²
Area of 6 faces= 25 × 6= 150 cm².
So, that means,
T.S.A= 150 Cm²
Solve for x, rounding to the nearest tenth if necessary.
Answers
Answer:
Pythagorean theorem: a^2 + b^2 = c^2, a and b are the sides, c is the hypotenuse (longest side).
27^2 + 25^2 = x^2
Solving for x, we see that it is approximately 36.8.

Answers
Answer:
≈ 12.6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the third side, then
x² + 6² = 14²
x² + 36 = 196 ( subtract 36 from both sides )
x² = 160 ( take the square root of both sides )
x = [tex]\sqrt{160}[/tex] ≈ 12.6 ( to the nearest tenth )
Mary bought 5 pairs of gloves and 2 hats for $95. Mary received a text from her friend Joanna ask her to buy 4 pairs of gloves and a hat. Mary told Joanna that the cost was $70. How much does each pair of gloves cost? How much does the hat cost?
Answers
Answer: Each pair of gloves costs $15 and each pair of hat costs $10.
Step-by-step explanation:
Let x = Cost per pair of gloves
y= Cost per hat.
As per given, we have
[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]
Multiply (ii) by 2 , we get
[tex]8x+2y=140\ \ \ \ (iv)[/tex]
Eliminate (i) from (iv), we get
[tex]3x=45\\x=15[/tex]
Put this in (ii), we get
[tex]4(15)+y=70\\60+y=70\\y=10[/tex]
Hence, each pair of gloves costs $15 and each pair of hat costs $10.

What are the six trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
The given function is f(x)= asin(b(x-h)) where we have to find the value of a , b and h.
f(x)= sin 2x – 3 cos 2x
If we substitute the value of a, b and h then we get the same solution for both the equation.
a = 3.16
b = 2
h = 0.62
Thus, option B is the correct match for the values.

[tex] =\tt 2x\pi = 12\pi[/tex]
