Answer:2d+3
2(8)+3
Multiply 2 and 8
16+3
19
So the answer is 19
Step-by-step explanation:
ANSWER
C) 5.1 units
EXPLANATION
The coordinates of A are (5,2).
If this point is translated 1 unit to the left and 5 units down to create point A'.
Then A' has coordinates


The distance between A and A' is calculated using the distance formula,




We round to the nearest tenth to obtain,

The measurement that is closed to the distance is 5.1 units
First, let x or any variable represent the number of paintings Kate initially has. After selling 12 of it, her paintings now becomes only x - 12. Then, she purchased 7 more making the number of her paintings become x - 12 + 7 = x - 5. This number tantamount to 21.
x - 5 = 21 ; x = 26
Thus, Kate initially had 26 paintings.
-3x + 4y = 12
x - y = 1....x = y + 1
-3(y + 1) + 4y = 12
-3y - 3 + 4y = 12
-3y + 4y = 12 + 3
y = 15
x - y = 1
x - 15 = 1
x = 1 + 15
x = 16

The height of lighthouse is 52.2 yards
<em><u>Solution:</u></em>
Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41 degree
The diagram is attached below
Consider a right angled triangle ABC
AB is the height of the lighthouse
BC is the distance between the base of a lighthouse and Photographer
As per given, BC = 60 yards
Angle between the ground and the top of the lighthouse is 41 degree
Angle ACB = 41 degree
<em><u>To find: height of lighthouse i.e AB = ?</u></em>
We know that,

Here Base is BC and perpendicular is AB

Substituting the values,

Thus the height of lighthouse is 52.2 yards
