Answer:

f(n) = 5n - 67

Step-by-step explanation:

Given

f(1)=−62
f(n)=f(n−1)+5

Property of AP

aₙ = a₁ + (n-1)d
a₁ = -62, d = 5

Applying same on the given function

f(n) = -62 + (n-1)*5 = -62 + 5n - 5 = 5n - 67
f(n) = 5n - 67

Answer:

$5\sqrt{8}$

$24\sqrt{3}$

Step-by-step explanation:

To simplify the square roots, break the number under the square root into factors. Any factors which are perfect squares may be simplified to outside the square root.

$\sqrt{200}=\sqrt{25*8} =\sqrt{25}*\sqrt{8}= 5*\sqrt{8} =5\sqrt{8}$

and

$4\sqrt{108}=4\sqrt{27*4} =4*\sqrt{27}*\sqrt{4}=4* \sqrt{9} *\sqrt{4}*\sqrt{3} =4*3*2*\sqrt{3}=24\sqrt{3}$

What is the scale factor & the length of x & y?

Natali5045456 [20]

Answer:

see explanation

Step-by-step explanation:

The scale factor is the ratio of corresponding sides, image to original, thus

scale factor = $\frac{4}{6}$ = $\frac{2}{3}$ , then

x = $\frac{2}{3}$ × 9 = 2 × 3 = 6

y = $\frac{2}{3}$ × 7 = $\frac{14}{3}$

Is this a function? Plz help and i will give you brainlest

lisov135 [29]

Answer:

Step-by-step explanation:

A function cannot have 2 outputs for one input.

You should only ever have on value correlate with another.

4 as x has two outputs, 0 & 3 making it not a function

Find the area and perimeter of an isosceles trapezoid with a 60° base angles and bases 9 and 13.

BlackZzzverrR [31]

The trapezoid has two right triangles each with one side of length (13-9)2 = 4/2 = 2.

The other side of each right triangle is such that tan 60° = Heigth / 2

Then height = 2*tan60°.

The area of the trapezoid is height * (base 1 + base 2)/2

Then area = 2*tan (60°) * (13+9)/2 = 38.11
