zalisa [80]3 years ago
4 0

Total units would be: 4+7 = 11

value of 1 unit = 44/11 = 4

Ratio would be: 4(4) & 7(4) = 16 & 28

In triangle XYZ, angle Y = 45º and angle Z = 60º. If XZ = 4, then what is XY?
Katena32 [7]

Answer:

XY = 4.9

Step-by-step explanation:

Given

XZ= 4

\angle Y = 45

\angle Z = 60

Required

Determine the measure of side XY

To do this, we make use of sine law. This is as follows:

\frac{a}{\sin\ A} = \frac{b}{\sin\ B} = \frac{c}{\sin\ C}

In this case:

\frac{4}{\sin(45)} = \frac{XY}{\sin(60)}

Cross Multiply

XY * \sin(45) = 4 * \sin(60)

XY * 0.7071 = 4 * 0.8660

Make XY the subject

XY = \frac{4 * 0.8660}{0.7071}

XY = \frac{3.4640}{0.7071}

XY = 4.89888276057

XY = 4.9 -- <em>approximated</em>

Which graph represents f(x)=log3x 1?
exis [7]

The correct option A: graph A, shows the logarithmic function;

f(x) = log₃x + 1

<h3>Explain the term logarithmic function?</h3>
  • The opposite of such an exponential function is a logarithmic function.
  • A log function and then an exponential function both use the same base.
  • An exponent is a logarithm. f(x) = bx is how the exponential function be expressed.
  • The formula again for logarithmic function is f(x) = log base b of x.

f(x) = log₃x + 1

  • When x = 1

f(1) = log₃1 + 1

f(1) = 0 + 1

f(1) = 1

(1, 1)

  • When x = 3

f(3) = log₃3 + 1

f(3) = 1 + 1

f(3) = 2

(3, 2)

Thus, the graph must contain the points   (1, 1), (3, 2).

Therefore, graph A define the given logarithmic function;

f(x) = log₃x + 1.
