Sorry i only know questions one and two but
for question one 4/10 and 40% (i just converted the fraction to a decimal)
same for question two but its 6/10 and 60%
there are 10 letters in courageous
Yes it's a proportional relationship since its a constant rate and does not have a y-intercept
154/22 sales = $7/sale
<span>$7/sale(35 sales) = $245 </span>
<span>He will earn $245 for 35 sales.</span>
B. a parallelogram with four congruent sides
Answer:
- sin = -√3/2
- cos = -1/2
- tan = √3
- sec = -2
- csc = (-2/3)√3
- cot = (√3)/3
Step-by-step explanation:
See the attached picture for a drawing of the angle and its terminal point coordinates. Those are (cos(4π/3), sin(4π/3)), so we have the following trig function values:
sin(4π/3) = -√3/2
cos(4π/3) = -1/2
tan(4π/3) = sin/cos = √3
sec(4π/3) = 1/cos = -2
csc(4π/3) = 1/sin = -(2√3)/3
cot(4π/3) = 1/tan = (√3)/3

<em>Additional comment</em>
It helps to know that 1/√a = (√a)/a. This lets you write the ratios with a rational denominator in each case.
