What is the value of this expression when c=-4 and d = 10?
1/4(c3+d2)

What is the value of this expression when c = -4 and d = 10 ? (c³ + d²)

(c³ + d²) where c = -4 and d = 10

The value of the expression (c³ + d²)

(c³ + d²) [Given expression]

Now, putting the value of c = -4 and d = 10 , we get,

{ (-4)³ + (10)² }

( -64 + 100 )

( 36 )

× 36

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
