Answer: 15in^2
Step-by-step explanation:
first you need to find the area of the rectangle, so you would multiply 7 and 3, which gives you 21, (A=L•W). So now you need to find the area of the triangles, the formula for that is A= 1/2 b•h, so you get 3in for the area of the triangle, but since there are two and they are the exact same triangle you would just combine them, so the area for both triangles is 6in, so then you would need to subtract the 6 from the 21 so that you can find the area of the shape, and your final answer would be 15in(squared). hopefully you understand
Answer:
False
Step-by-step explanation:
The statement itself is wrong in the textbook is given that if a number is a rational then it si the additive inverse of the stsrement
Answer:
1.5 - it represents the time in seconds where the ball is highest
Step-by-step explanation:
There are 2 methods of approaching this.
The first method involves graphing, simply place into a graphing calculator and view the vertex. The horizontal line coming down from the vertex is the axis of symmetry (it splits the parabola in half).
The second method is finding the axis of symmetry (vertex) algebraically.
-b/2a is the equation used to find the x term of the vertex, and if we were to substitute our values in, we'd get -48/-32, giving us 1.5
Answer:
See below
Step by step explanation:
Here it is given that , the price of a ticket is $42.99 before tax . And he got a discount of 40% . So the cost after discount will be ,
Simplify ,
Again it is given that he paid a tax of 7% on the discounted price . So the tax paid in dollars will be ,
Simplify ,
Answer of Part A : <em>H</em><em>e</em><em> </em><em>p</em><em>a</em><em>i</em><em>d</em><em> </em><em>a</em><em> </em><em>sales</em><em> </em><em>t</em><em>a</em><em>x</em><em> </em><em>o</em><em>f</em><em> </em><em>$</em><em>1</em><em>.</em><em>8</em><em>0</em><em> </em><em>.</em>
Now the total amount paid can be calculated by adding sales tax to the cost after discount .

Add ,

Answer: C): when showing trends
Step-by-step explanation:
A Line graph connects different points such that it appears as a line. For this reason it is very useful in showing the trend in the movement of values overtime.
When plotting line graphs the independent variable for example 'months' is usually put on the x-axis and a dependent variable such as 'temperature' will be on the y-axis.
When plotted, the line will be able to show just how things have changed overtime such that the change is quite easy to see through the movement of the line.
