Find the f(0) and f(1)
Kruka [31]

Answer:

C

Step-by-step explanation:

to evaluate substitute x = 0 and x = 1 into f(x)

note that a^{0} = 1

f(0) = 45 × (1/3)^{0} = 45 × 1 = 45

f(1) = 45 × (1/3)^{1} = 45 × \frac{1}{3} = 15

If BTS=GHD BS=25 TS=14 BT=31 GD=4x-11 S=56 B=21 and H=(7y+5) find the values of x and y
77julia77 [94]

Given:

Consider the completer question is "If ∆BTS≅∆GHD, BS=25, TS=14, BT=31, GD=4x-11, m∠S=56, m∠B=21 and m∠H=(7y+5), find the values of x and y.

To find:

The values of x and y.

Solution:

We have,

\Delta BTS\cong \Delta GHD       (Given)

BS=GD                       (CPCTC)

25=4x-11

25+11=4x

36=4x

Divide both sides by 4.

9=x

In ∆BTS,

\angle B+\angle T+\angle S=180^\circ    (Angle sum property)

21^\circ+\angle T+56^\circ=180^\circ

77^\circ+\angle T=180^\circ

\angle T=180^\circ-77^\circ

\angle T=103^\circ

Now,

\angle T=\angle H            (CPCTC)

103=7y+5

103-5=7y

98=7y

Divide both sides by 7.

14=y

Therefore, the value of x is 9 and value of y is 14.

Which of the following is a valid exclusion for the algebraic fraction 8ab^2x/4a^2b - 8ab^2
avanturin [10]

The valid exclusion of the algebraic fraction is (c) a =0, b =0, a =2b

<h3>How to determine the valid exclusion?</h3>

The expression is given as:

8ab^2x/4a^2b - 8ab^2

Set the denominator to 0

4a^2b - 8ab^2 = 0

Divide through by 4ab

a - 2b = 0

Add 2b to both sides

a = 2b

Hence, the valid exclusion of the algebraic fraction is (c) a =0, b =0, a =2b
