Fill in the missing values to make the equations true.

Mathematics
1 answer:
azamat3 years ago
5 0

Step-by-step explanation:

Some of the property of log are as follows :

1. \text{log a}-\text{log b}=\text{log} \dfrac{\text{a}}{\text{b}}

2. \text{log a}+\text{log b}=\text{log}(a{\cdot} b)

3. \text{log}a^n=n\ \text{log} a

Now coming to question,

(a) \text{log 5}-\text{log 8}=\text{log} \dfrac{\text{5}}{\text{8}} (using property 1)

(b) \text{log 1}+\text{log 3}=\text{log}(1{\cdot} 3)=\text{log} 3 (using property 2)

(c) \text{log} 4=\text{log} 2^2=2\ \text{log} 2 (using property 3)

Hence, this is the required solution.

lutik1710 [3]

Answer:

y=2x+17

Step-by-step explanation:

y-y1=m(x-x1)

y-1=2(x-(-8))

y-1=2(x+8)

y=2x+16+1

A rectangular soccer field is 120 ft long by 64 ft wide. What dimensions would a scale drawing of the soccer field be if the fie
timofeeve [1]

Answer:

Hence dimension on drawing= 12 in by 6.4 in

Step-by-step explanation:

Actual dimension of the soccer field is 120 ft by 64 ft

Scale during drawing = 1in to 10 ft

Hence dimension on drawing = 120/10 by 64/10 = 12 in by 6.4 in

Which answer shows a reflection across the y-axis?<br><br> A<br> B<br> C<br> D
padilas [110]

Answer:

D

Step-by-step explanation:

The y axis is the vertical axis; the one going up and down.

A reflection means that a point is an equal distance away from its reflector as the basis was.

A was a reflection across the line y=x.

B was a reflection across the x axis with a 90 degree rotation.

C was a reflection across the x axis.

That leaves D.

Use OZ with VWXY<br> What is XY ?<br><br> A 30<br> B. 35<br> C. 40<br> D. 50
valkas [14]

Answer:

Step-by-step explanation:

Chords having equal measures are equidistant from the center of the circle.

Since, VW = XY

Therefore, ZP = ZR = 15 units

A perpendicular line drawn from the center of a circle to the chord is the bisector of the chord.

VR = WR = 20 units

By applying Pythagoras theorem in ΔZRV,

ZV² = ZR² + VR²

ZV² = (15)² + (20)²

ZV = √(225 + 400)

ZV = √625

ZV = 25 units

Therefore, measure of radius ZV = 25 units.

VW = XY [Given]

Therefore, XY = 2(20)

                        = 40 units
