PLEASE HELP ME I AM ON A TEST . WILL MARK BRAINLIEST
tekilochka [14]

Answer:

A. -2

B. -10

Step-by-step explanation:

Given the equation of the line

y=\dfrac{1}{2}x-1

Its slope is \frac{1}{2}.

A. Perpendicular line has the slope m, for which

\dfrac{1}{2}\cdot m=-1\Rightarrow m=-2

B. The equation of the perpendicular line will be in the form

y=-2x+b

This line passes through the point (-6,2), substitute its coordinates into the equation:

2=-2\cdot (-6)+b\\ \\2=12+b\\ \\b=2-12\\ \\b=-10

So, y-intecept is -10.

What is the equation of a line that contains the point (4, 0) and is parallel to x + y = 2?
gogolik [260]

Answer:

x + y = 4 or y = -x + 4

Step-by-step explanation:

0 = -1[4] + b

4 = b

y = -x + 4

If you want it in <em>Standard</em><em> </em><em>Form</em>:

y = -x + 4

+x +x

_________

x + y = 4 >> Line in Standard Form

* Since the <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] is -1 and that parallel lines have SIMILAR SLOPES, -1 remains the same.

I am joyous to assist you anytime.

Compute i^1+i^2+i^3....i^99+i^100
fgiga [73]

Good morning ☕️

Answer:

<h3>i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰ = 0</h3>

Step-by-step explanation:

Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰

S =  i¹ +  i² +  i³ + . . . + i⁹⁹  +  i¹⁰⁰

S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀

then, S is the sum of 100 consecutive terms of a geometric sequence (an)

where the first term a1 = i¹ = i  and the common ratio = i

FORMULA:______________________

S=(term1)*\frac{1-(common.ratio)^{number.of.terms}}{1-(common.ratio)}

_______________________________

then

S=i*\frac{1-i^{100} }{1-i}

or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1  (we know that i⁴ = 1)

Hence

S = 0
