The y-intercept is: y = 7x - 44
Answer:
75 %
Step-by-step explanation
There are 5 squares and each has 25 so 75% is the answear
Answer:
The percentage by which the booster club fell short is 33% as shown on the chart
Step-by-step explanation:
To represent the given data pictorially, a pie chart is suitable
The circumference of the pie chart will represent the amount to be raised by the booster club and a sector of the circle which is two-thirds of the circumference represents the amount raised
Given that the amount raised = 2/3×Goal = $15,000, we have;
We represent the amount raised as a sector of the circle as follows;
Sector angle = 2/3×360° = 240°
Total sector of goal amount = Entire circle = 360°
Amount club fell short = 360° - 240° = 120°
The goal amount = 3/2 × $15,000
Percentage by which the club fell short = 120/360×100 = 1/3×100 = 33.33%
Hello,
We suppose cos (x)≠0 and sin(x)≠0
cos(x)+sin(x)=√2 cos(x)
==>1+tg(x)=√2
==>tg(x)=√2-1
==>1/tg(x)=1/(√2-1)
==>cos (x)/sin(x)= √2+1
==>cos(x)=sin(x)+√2*sin(x)
==>cos(x)-sin(x)=√2 sin(x)
