Answer:
11/15 OR 0.73
Step-by-step explanation:
2/5 ---> 6/15
1/3 ---> 5/15
6/15 + 5/15 = 11/15
OR
2/5 ---> 0.4
1/3 ---> 0.33
0.4 + 0.33 = 0.73

Answer:
1040
Step-by-step explanation:
substitute the given information
h = 36
s = 10,000
E = 15 x 36 + 0.05 x 10,000
E = 540 + 500 = 1040

Find the coordinates of the point at which the normal to the curve y = x ^ 2 at x = 1 meets the curve again
Answer:
[tex](-\frac{3}{2},\frac{9}{4})[/tex]
Step-by-step explanation:
A normal line is a line perpendicular to the tangent line, so we must take the derivative of the function to find the slope of the tangent line, and then take the opposite reciprocal of this slope, to find the slope of the normal line. The equation of a normal line will be in the form of [tex]y=mx+b[/tex]:
[tex]f(x)=x^2\\\\f'(x)=2x\\\\f'(1)=2(1)\\\\f'(1)=2[/tex]
Hence, the opposite reciprocal is [tex]-\frac{1}{2}[/tex], which is our slope for the normal line. Now, we find the y-intercept by plugging in the given coordinate point [tex](1,1)[/tex] since [tex]f(1)=1^2=1[/tex]:
[tex]y=-\frac{1}{2}x+b\\\\1=-\frac{1}{2}(1)+b\\ \\1=-\frac{1}{2}+b\\ \\b=\frac{3}{2}[/tex]
Thus, the equation of the normal line is [tex]y=-\frac{1}{2}x+\frac{3}{2}[/tex]. Using this information, we can now find the coordinates where the normal of the curve at x=1 meets the curve again:
[tex]x^2=-\frac{1}{2}x+\frac{3}{2}\\ \\ x^2+\frac{1}{2}x-\frac{3}{2}=0\\ \\ 2x^2+x-3=0\\\\(x-1)(2x+3)=0\\\\x=1,\: x=-\frac{3}{2}[/tex]
Since we only care about [tex]x=-\frac{3}{2}[/tex] since [tex]x=1[/tex] was already accounted for, the y-coordinate would be:
[tex]y=x^2\\\\y=(-\frac{3}{2})^2\\\\y=\frac{9}{4}[/tex]
Therefore, the coordinates are [tex](-\frac{3}{2},\frac{9}{4})[/tex].
In the graph attached below, you can see the tangent line [tex]y=2x-1[/tex] and how it is perpendicular to [tex]y=\frac{1}{2}x-\frac{3}{2}[/tex].

4/3 [tex]\geq[/tex] x
Step-by-step explanation:
[tex](\sqrt{x+4})^ {2} \geq (2\sqrt{x})^{2}\\[/tex]
x + 4 [tex]\geq[/tex] 4x
4 [tex]\geq[/tex] 4x - x
4 [tex]\geq[/tex] 3x
4/3 [tex]\geq[/tex] x
Solution:
[tex]\sqrt{x + 4} \geqslant 2 \sqrt{x} [/tex]
Square both sides.[tex] = > ( \sqrt{x + 4)} ^{2} = (2 \sqrt{x} ) ^{2} \\ [/tex]
In the LHS, square and square root gets cancelled out. In the RHS, do the square.[tex] = > x + 4 \geqslant {2}^{2} x \\ = > x + 4 \geqslant 4x[/tex]
Transpose x to the RHS.[tex] = > 4 \geqslant 4x - x \\ = > 3x \leqslant 4 [/tex]
Now, divide both sides by 3.[tex] = > \frac{3x}{3} \leqslant \frac{4}{3} \\ = > x \leqslant \frac{4}{3} [/tex]
Answer:
[tex]x \leqslant \frac{4}{3} [/tex]

Based on the special angles formed by transversal and parallel lines, the missing variables are:
z = 86°
y = 75°
x = 105°
w = 94°
What are Special Angles Formed by a Transversal and Two Parallel Lines?Vertical angles formed are congruent.Consecutive angles formed are supplementary.Alternate interior angles that are formed are congruent also.Thus:
z = 86° (vertical angles)
y = 75° (alternate interior angles)
x = 180 - 75 = 105° (supplementary)
w = 180 - 86 = 94° (supplementary)

Based on the SSS similarity theorem, △ABC ~ △PQR because AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5 (option D).
The SSS Similarity TheoremTwo triangles having three pairs of sides that are proportional can be proven to be similar by the SSS similarity theorem.
If the triangle ABC and triangle PQR are similar, their corresponding sides will be proportional, meaning that: AB/PQ = BC/QR = CA/RP.
Therefore, using the distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex], the sides of each triangle is found.
Therefore, it shows that:
AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5
Therefore, based on the SSS similarity theorem, △ABC ~ △PQR because AB/PQ = BC/QR = CA/RP = √2/√5 = √10/5 (option D).

The characteristics a rhombus and a rectangle always have in common is opposite sides with equal length.
The right option is opposite sides with equal length
From the question,
We are to determine which of the given characteristics do a rhombus and a rectangle always have in common.
To determine which of the characteristics, we will list some of the characteristics of the two shapes
Characteristics of a Rhombus
All sides are of equal length
Opposite sides are parallel
Opposite angles are congruent
Diagonals intersect perpendicularly
Consecutive angles are supplementary
Characteristics of a Rectangle
Opposite sides are congruent and parallel
Diagonals bisect each other
Each of the interior angles is a right angle
Diagonals are congruent
Now, from above,
We have that all the sides of rhombus are equal in length, which makes the opposite sides to be equal as well.
Also, among the characteristics of a rectangle is that, opposite sides are equal in length
Hence, the characteristics a rhombus and a rectangle always have in common is opposite sides with equal length. The right option is opposite sides with equal length
