What is length of Ef?
A.10
B.15
C.20
D.v200
E.v300
F.v500
Answer:
Answer E is correct
Step-by-step explanation:
Let the Length of EF be x
Use PYTHAGORAS theorem to find the length of EF
EF² + DF² = DE²
[tex] {x}^{2} + {10}^{2} = {20}^{2} \\ {x}^{2} + 100 = 400 \\ {x}^{2} = 400 - 100 \\ {x}^{2} = 300 \\ x = \sqrt{300} [/tex]
So,
[tex]EF = \sqrt{300} [/tex]
Hope this helps you.

24. Find the perimeter and area of the triangle below.
базь
2a3b
4ab
Answer:
Answer to the first part: 8a³b + 4ab
Step-by-step explanation:
Perimeter = distance around the three sides
P = 6a³b + 2a³b + 4ab
P = (6a³b + 2a³b) + 4ab add like terms
P = 8a³b +4ab Simply
The value of the perimeter and area of the triangle are,
20.52 cm² and 28.68 cm
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Now, By Using Pythagoras theorem to find the base of the triangle as;
a² = 6² - 3²
a ² = 27
a = √27
And, b² = 9² - 3²
b² = 72
b = √72
Hence, Base = √27 + √72
= 13.68
So, We get;
Area = 0.5 x 13.68 x 3
Area = 20.52 cm²
And, The value of perimeter is,
Perimeter = 9 + 6 + 13.68
= 28.68
Thus, The value of the perimeter and area of the triangle are,
20.52 cm² and 28.68 cm

Hiiii again, How should this model be completed?
9514 1404 393
Answer:
see attached
Step-by-step explanation:
You have the relation ...
(left side number) × (top number) = (number in the area box)
This means ...
(top number) = (number in the area box)/(left side number)
top number = 680/17 = 40 . . . number in the quotient box
and ...
17 × 8 = number in the area box = 136
__
The number in the right-side box is the remainder, the difference between the dividend 820 and the sum of the numbers in the other two area boxes.
820 -680 -136 = 4 . . . . number in the right-side box
the flag of a country contains an isosceles triangle. (Recall that an isosceles triangle contains two angles with the same measure.) If the of the third angle of the triangle is 40° more than three times the measure of either of the other two angles, find the measure of each the triangle. (Recall that the sum of the measures of the angles of a triangle is 180°.)
The two equal angles are each 36°.
The third angle is 108°.
Oliver incorrectly states that the expression tan(3pi/4 + x) can be simplified as -1. Review Oliver’s work. Which statement explains why Oliver is incorrect?
Keyword gibberish:
The expression does not simplify not have a value if simplified to not equivalent to not
tan startfraction 3 pi over 4 endfraction + x
We want to see where Oliver is making a mistake in his claim.
The correct option is the first one, the simplification on the last step is wrong.
We start with the expression:
[tex]tan( \frac{3*pi}{4} + x)[/tex]
Now, by looking at Olvier's work, we can see that on the last step he writes:
[tex]\frac{-1 + tan(x)}{1 + tan(x)} = -1[/tex]
This is clearly wrong, as the numerator and the denominator are dont simplify to -1 (this only happens if the numerator is -1 times the denominator), so the left side can't be equal to -1, it actually would be simplified to:
[tex]\frac{-1 + tan(x)}{1 + tan(x)} = \frac{-1 +1 - 1 tan(x)}{1 + tan(x)} = \frac{-2 + 1 + tan(x)}{1 + tan(x)} \\\\\frac{-2 + (1 + tan(x))}{1 + tan(x)} = \frac{-2 }{1 + tan(x)} + \frac{ 1 + tan(x)}{1 + tan(x)} = \frac{-2 }{1 + tan(x)} + 1[/tex]
Then the correct option is the first option.

The value of Δy using the function y= 5x^3 as x goes from -2 to 1 is; Δy = 45
The question requests that Δy be computed according to the function, y = 5x³ as x goes -2 to 1.
Δy = y2 - y1where:
y1 = 5(-2)³y1 = -40and
y2 = 5(1)³y2 = 5Therefore,
Δy = y2 - y1Δy = 5 - (-40)Δy = 45.
