Answer:
C
Step-by-step explanation:
y= 60(2)+10
y=130
y=65(2)
y=130
A. 2x2 – 4x – 6
Looking at the diagram, there two positive x's to the power of 2, and there are four negative x and six minus signs. Inspecting it and adding all the same terms, you will get the quadratic expression 2x^2 - 4x - 6.
The length and width of rectangular traffic sign are 40 and 30 inches respectively
<h3><u>Solution:</u></h3>
Given that,
Perimeter of rectangular traffic sign = 140 inches
Let length and width be denoted as ‘L’ and ‘B’ respectively
Given that length is 10 inches longer than its width
L = 10 + B
<em><u>The perimeter of rectangle is given as:</u></em>
Perimeter = 2( L + B)
On substituting the values, we get
140 = 2(10 + B + B)
140 = 2(10 + 2B)
140 = 20 + 4B
B = 30
Therefore, the length is L = 10 + 30 = 40
Hence the dimensions length and width of the rectangle are 40 and 30 inches respectively.
Solution
- The correct steps for drawing a circle in a triangle are given below:
1. Bisect one of the angles
2. Bisect another angle
3. Where they cross is the center of the inscribed circle, called the incenter
4. Construct a perpendicular from the center point to one side of the triangle
5. Place compass on the center point, adjust its length to where the perpendicular crosses the triangle, and draw your inscribed circle!
- Based on these steps above and comparing them with the steps given in the question, every step given in the question is correct except Step 1.
- Step 1 given in the question, says we should construct a perpendicular bisector of one angle in the triangle. This is not correct because of the use of perpendicular bisector. This is only used for bisecting lines, not angles.
