Answer: -5, 6, and 9
Step-by-step explanation:
A) 4+5x=y
B) f(x)=5x+4
c) Start at your y-intercept (0,4). Your slope is 5/1, therefore you go 5 up the y axis and 1 over on the x axis from the y-intercept. You should end up on the point (9,1)
Answer:
Step-by-step explanation:
Given the modulus of a complex number |z1| = 6 and its argument θ1 = 70°
If z1 = a+bi, according to definition;
|z1| = √a²+b²
|z1|² = a²+b²
Since |z1| = 6, |z1|² = 6² = 36
a²+b² = 36 .......... 1
Also the argument is derived from the expression
tan θ = b/a
tan 70 = b/a
b/a = 2.75
b = 2.75a ........ 2
Substitute equation 2 into 1
a²+b² = 36
a²+(2.75a)² = 36
a²+7.5625a² = 36
8.5625a² = 36
a² = 36/8.5625
a² = 4.204379
a = √4.204379
a = 2.051 (to nearest thousandth)
Since b = b = 2.75a
b = 2.75(2.051)
b = 5.639 (to nearest thousandth)
z1 = 2.051+5.639i
D. 663 square meters is the anwser
