Answer:
Choice C
Y = (3)(9)^x
Step-by-step explanation:
The standard form for an exponential function is y = ab^x.
Where a is the initial value, and b is the exponential growth or decay.
Answer:
Step-by-step explanation:
(a). SR = 15√2 km ≈ 21.2 km
R is 21.2 km due South-East of S
(b). RQ² = 35² + 15² ⇒ RQ = 5√14 km ≈ 38.1 km
R is 38.1 km due South-West of Q


To solve these type of problems you need to use the pythagoras theorem ⇨ Hypotenuse² = Base² + Altitude².
Here,
- Altitude = 1.6 cm.
- Base = 1.2 cm
- Hypotenuse = x
Now, let's solve for x.
Hypotenuse² = Base² + Altitude²
x² = (1.2)² + (1.6)²
x² = 1.44 + 2.56
x² = 4
x = √4
x = <em><u>2</u></em><em><u>.</u></em>
- So, the value of x is <em><u>2</u><u> </u><u>cm.</u></em>

- Pythagoras theorem can be used only in the cases of right-angled triangles. Here, it's given that the triangle is right angled so we can use this theorem.
- To solve the squares if decimals, take them as whole numbers & then just add the decimal points. For example, ⇨ for (1.2)², take it as 12² , then multiply 12 by 12, you'll get 144. Now, add the decimal place accordingly ⇨ 1.44 . So, (1.2)² = 1.44.
