Answer:
Step-by-step explanation:
f(x)=4/5x^2+12x
For f(5)
: f(x) = 4/5(5)2 + 12(5)
= 4/5 × 25 + 60
= (4×5) + 60
= 20 + 60
= 80
Answer: 65/63
Step-by-step explanation:
The cosecant of angle N is the reciprocal of the sine of angle N.
Using SOHCAHTOA, the sine of angle N is 63/65.
This means that the cosecant of angle N is 65/63.
Answer:
(3a +6b) (9a² - 18ab + 36b²)
Step-by-step explanation:
27 = 3 * 3 * 3 = 3³
216 = 6 * 6 * 6 = 6³
a³ + b³ = (a + b)(a² - ab + b²)
27a³ + 216b³ = (3a)³ + (6b)³
= (3a + 6b)( (3a)² - 3a*6b + (6b)² )
= (3a +6b) (9a² - 18ab + 36b²)
First, find the value of <em>x</em>. Then, use the measures of the arcs to find the value of <em>w</em>.
When two chords intersect, the measure of the internal angle is equal to the average of the arcs that it encloses:
Since the angle of 70° encloses arcs of 60° and x°, then:
Solve for <em>x:</em>
The sum of the measures of the arcs of a circle must be equal to 360°. Then:
Substitute <em>x=80</em> and solve for <em>w:</em>
Therefore, the value of w is:
Yes they are equal because lets say the rectangle's area is 14 and if you divide 14 into 2 it will be 7 and 7+7=14
