Answer:
1. 8
2. 24
Step-by-step explanation:
The number of persons that drink grape milk only :
18 - 10 = 8
The number of persons that drink coffee :
42 - 8 = 34
The number of persons that drink coffee only :
34 - 10 = 24
Answer:
(a)4.17 metres
(b)6.9999 seconds
(c)f⁻¹, t= 2ᶠ⁽ᵗ⁾
Step-by-step explanation:
f(t)=log₂t
(a) If t=18 seconds
f(18)=log₂18= log ₂(2X9)
=log ₂2 + log ₂9
=1+(log9/log2)
=1 + 3.1699 =4.17 metres
f(18)=4.17 metres.
(b)If f(t)=2.80735, we want to determine the value of t.
f(t)=log₂t
2.80735=log₂t
Changing from logarithm form to index form
t= 2^(2.80735)
=6.9999 seconds
(c)f(t)=log₂t
Next, We want to determine f⁻¹
If y=log₂t
Changing to exponential form
t=2ʸ
f⁻¹, t= 2ᶠ⁽ᵗ⁾.
Answer:
D. 37
Explanation:
Add the bags of beads she bought to the ones she found (1288+784)
Then divide the total by 56(2072÷56)
The simplified form of the expression √(100x³⁶) will be 10x¹⁸. Then the correct option is A.
<h3>What is simplification?</h3>
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The expression is given below.
⇒ √(100x³⁶)
Then the simplified form of the expression will be
⇒ √[(10x¹⁸)²]
⇒ 10x¹⁸
Then the correct option is A.
