Answer:
The equation for the area of a circle is A = πr².
If you double the radius, the area increases exponentially by a factor of two. The area will be squared.
Step-by-step explanation:
step 1. KITE is a kite
step 2. <ski + <kis + 90 = 180 (internal angles of a triangle has a sum of 180)
step 3. <ski + 25 = 90
step 4. <ski = 65°
step 5. <kes = <kis (angles across equal sides are equal)
step 6. <kes = 25°
step 7. <kie = <kis (they are the same angle)
step 8. <kie = 25°.
step 9. let's call ek = x and et = 1 5x
step 10. therefore x + 1.5x + x + 1.5x = 55
step 11. 5x = 55 or x = 11 = ek
step 12. et = 1.5x = 1.5(11) = 16.5.
The notation V(r) actually gives the volume of air inside the basketball. V(r) is volume as a function of radius, r It can be written as: V(r) = 4/3πr³ So, for any value of r, we can get the volume V. For, example, when r = 7cm we can say; V(7) = 4/3 x 22/7 x 7³ = 1437.33 cm³
We are going to rewrite the functions correctly:
f (x) = (1/4)
f (x) = (0.4) ^ x
f (x) = 4 ^ x
f (x) = (1/2) ^ x
We observe that we have functions of the form:
f (x) = A (b) ^ x
When
b> 1 The function grows
b <1 Function decreases
Therefore, the function that is growing is:
f (x) = 4 ^ x
Answer:
The function that is increasing is:
f (x) = 4 ^ x
