Answer:
None of the above
Step-by-step explanation:
The figure3 shows 1 side and 1 angle of one triangle congruent to 1 side and 1 angle of the other triangle. We are not shown anything else, so the answer is:
None of the above
and you can't prove the triangles congruent.
Answer:
Part a) Tim has completed the greater amount of work
Part b) They have completed together of the project or of the project
Step-by-step explanation:
Part a) Who has completed the greater amount of work?
we have
Jaime has 5/11 of a project completed
Tim has 7/13 of a project completed
Multiply 5/11 by 13/13 and 7/13 by 11/11
so
Jaime --->
Tim --->
Remember that
When fractions have the same denominator, the larger fraction is the one with the larger numerator
therefore
Tim has completed the greater amount of work
Part b) How much of the project have they completed together?
we have that
Jaime has 65/143 of a project completed
Tim has 77/143 of a project completed
Sum the fraction of the project completed by Jaime plus the fraction of the project completed by Tim
Convert to percentage
Multiply by 100
Ok, the formula to find the area of a regular polygon is...
A = 1/2 nsr
In this equation...
n = number of sides
s= side length
r = apothem (radius of the inscribed circle)
To find the area, we must first find the apothem. The apothem is the radius of the inscribed circle (draw a line from the center of the figure to the center of one of the sides). If you draw the apothem in to the figure, it creates a right triangle with a hypotenuse of 13.07 in and one side length of 5 in (1/2 of the figure's side length). Now we can find the apothem with the formula
a^2 + b^2 = c^2
a^2 = c^2 - b^2
a^2 = 13.07^2 - 5^2
a^2 = 170.8249 - 25
a^2 = 145.8249
a = 12.076
Now we have the value for the apothem and we can plug it into the area formula...
A = 1/2 nsr
(recall that n = number of sides; s= side length; r= apothem)
A = 1/2(8×10×12.076)
A = 40×12.076
A= 483.04 in^2
Rounded to the nearest tenth would be...
483.0 in^2
Answer:
The range is [-11, ∞).
Step-by-step explanation:
f(x)=3x^2+6x-8
This is a parabola which opens upwards.
Convert to vertex form:
= 3(x^2 + 2x) - 8
= 3 [ (x + 1)^2 - 1] - 8
= 3(x + 1)^2 - 3 - 8
= 3(x + 1)^2 - 11.
The minimum value is -11 so the range is [-11, ∞).
