Answer:
9/49 is the answer
Step-by-step explanation:
The value of f(2a) is 8a
<h3>What is a function?</h3>
A function can be defined as a rule or expression that shows the relationship between a dependent and independent variable.
From the information given, we have;
g(a) = 4a
Let's determine the value for f(2a)
a = 2a
Let's substitute the value of a as 2a in the function
g(a) = 4a
g(2a) = 4 ( 2a)
Multiply through
g(2a) = 8a
Thus, the value of f(2a) is 8a

Answer:
The answer is 68°
Step-by-step explanation:
<h3>
<u>Given</u>;</h3>
- A right angled-triangle IGH.
- where, m∠G = 90°
<h3><u>To </u><u>Find</u>;</h3>
We know that
tan θ = Opp ÷ Adj
tan θ = 5 ÷ 2
tan θ = 2.5
tan θ = 68.2 ≈ 68
We know that tan 68 = 2.5
Thus, The m∠I is 68°

Answer:
y = 9.75
Step-by-step explanation:
Since both triangles are said to be similar, the proportion or ratio of the sides of both triangles would be equal.
Therefore, 39/y = 23/5.75 = 35/8.75
Let's find y
39/y = 23/5.75
==>Cross multiply
39*5.75 = 23*y
224.25 = 23y
==>Divide both sides by 23
224.25/23 = y
9.75 = y
y = 9.75
Check:
Thus,
39/9.75 = 23/5.75 = 35/8.75 = 4
Our answer y, which is 9.75, is correct.
