Which inequality best represents the phrase?
A number less then 0
A. n=0
B. n greater than n 0
C. n greater then n with a underscore on the bottom 0
D. n greater than 0 with a underscore 0
Im not sure what it is but my best bet would be on A because the rest of them all say greater than 0 and you are trying to find the least.
Answer:
n < 0
Step-by-step explanation:
Given that:
A number less than 0
Solve:
Since it saying that A number (n) is less than 0 it means it can't be greater.
From the following answer chioce:
[A] n=0
[B] n greater than n 0
[C] n greater then n with a underscore on the bottom 0
[D] n greater than 0 with a underscore 0
We can see that [B], [C], and [D] all saying greater than. While only [A] has a equal sign to 0.
I'm guess that [A] meant to be put as n < 0. Since the other are saying greater than. But if not. None of the above are correct.
< → less than
> → greater than
A number less than 0 ⇒ n < 0

A triangle has sides with lengths of 13ft, 82ft, and 83ft. Is it a right triangle
Answer:
NOT a right triangle

IF it is a right triangle, then the Pythagorean theorem would apply
13^2 + 82^2 = 83^2 ?????
169 + 6724 = 6889
6893 = 6889 ? No...it is NOT a right triangle

what is the value of (-2)6
with the six as a small number like ³
Answer:
64
Step-by-step explanation:
(-2)^6
6 is an exponent and basically it tells us to multiply the base, -2 by itself 6 times
so (-2)^6 is the same as saying -2 × -2 × -2 × -2 × -2 × -2
-2 × -2 × -2 × -2 × -2 × -2 = 64 so the value of (-2)^6 is 64
The angle of elevation to a nearby tree from a point on the ground is measured to be 64^{
∘. How tall is the tree if the point on the ground is 49 feet from the tree? Round your answer to the nearest hundredth of a foot if necessary
The height of the tree that forms an angle of 64 degrees and point from the tree is 49 feet is 100.46 ft
The situation forms a right angle triangle.
How to find the sides when given angle of elevationusing trigonometric ratios,
tan 64 = opposite / adjacent
Where
opposite side = height of the treeadjacent side = distance from the point on the ground from the tree.Therefore,
tan 64 = h / 49
cross multiply
h = 49 × tan 64
h = 49 × 2.05030384158
h = 100.464888237
h = 100.46 ft

Answer:
A reflection over the x-axis
Step-by-step explanation:
The X-axis is the horizontal line, and if G is the result of F, then figure F going up or down 6 units would make it uneven and it wouldn't look flipped.
Answer:
A, a reflection over the x-axis
Step-by-step explanation:
If you focus on one point of figure G (-5,5) you can apply the reflecting rule over the x-axis (change the y-coordinate's sign and leave the x-coordinate the same) and get the point (-5, -5) which fits the rule.
For each figure, find x. Then find the perimeter.

The approximate length of "y" from the given diagram is 2.0inches
Volume of prismsThe formula for calculating the volume of a prism is expressed as:
V = lwh
l is the length
w is the width
h is the height
Given that V =4 cubic inches, hence:
4 = x * x* x
4 = x^3
x = ∛4
x = 1.587
Using the pythagoras theorem;
y^2 =1.587^2 +1.587^2
y^2 = 5.037
y = 2.0in
Hence the approximate length of "y" from the given diagram is 2.0inches

Answer:
a = 39.2650873379cm
b = 11.5529459767cm
Step-by-step explanation:
a - Use the area of a triangle equation - 1/2 * a * b * Sin(C)
1/2 * 8 * 10 * Sin(79) = 39.2650873379cm
b - Use the cosine rule - c^2 = a^2 + b^2 - (2 * a * b * Sin(C)
64 + 100 - (2 * 8 * 10 * Cos(79)) = 133.4705607398
c = square root of 6.9396506484 = 11.5529459767cm

Answer:
Step-by-step explanation:
The cross sectional area of a basketball would indeed be a circle. The units for surface area would be meters squared. The units meters cubed would be volume. Area is inherently a 2-dimensional problem. Therefore, having 3-dimensional units makes no sense. In your case, the correct answer would be yards squared

how to complete the square?
Answer:
x = 12 and x = -6
Step-by-step explanation:
First subtract 6x on both sides to get a 2nd degree polynomial equal to zero:
[tex]x^2-6x-72=0[/tex]
To complete the square, the formula is to divide 'b' by 2 and square the result. The general form for a 2nd degree polynomial of the variable 'x' is as follows:
[tex]ax^2+bx+c=0[/tex]
For your case, b = 6. Therefore, the term that must be added and subtracted to our equation is:
[tex](6/2)^2=3^2=9[/tex]
Add and subtract 9 to our equation to get:
[tex]x^2-6x+9-9-72=0[/tex]
The first three terms form a perfect square, we have:
[tex](x^2-6x+9)-9-72=0[/tex]
[tex](x^2-6x+9)-81=0[/tex]
What multiplies to equal 9 but adds to equal -6? That would be -3 and -3. Therefore:
[tex](x-3)^2-81=0[/tex]
Add 81 to both sides to get:
[tex](x-3)^2=81[/tex]
We want to take the square root, but recall a square root has a positive and negative branch. Therefore we have two solutions:
[tex]x-3=9[/tex]
[tex]x-3=-9[/tex]
[tex]x=12[/tex]
[tex]x=-6[/tex]
