Answer:
x < 100
Step-by-step explanation:
x - 19 < 81
* add 19 to each side *
- 19 + 19 cancels out
81 + 19 = 100
x < 100
consider this equation tan(theta)=-5/3
if theta is an angle in quadrant II what is the value of sin(theta)
Answer:
B 5√34 / 34
Step-by-step explanation:
tan ∅ = opp/adj
In quad II
tan ∅ = 5 / (-3)
---------------------
hyp^2 = 5^2 + (-3)^2
hyp^2 =25 + 9 = 34
hyp = √34
---------------------------
sin ∅ = opp/hyp
sin ∅ = 5/√34
Rationalizing
sin ∅ = 5√34 / 34
Consider this equation [tex]tan(\theta)=-5/3[/tex]. if theta is an angle in quadrant II the of [tex]sin \theta = \dfrac{5\sqrt{34}}{{34} }[/tex].
What are the trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right-angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
Consider this equation
[tex]tan(\theta)=-5/3[/tex]
B 5√34 / 34
if theta is an angle in quadrant II what is the of sin(theta)
[tex]tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}[/tex]
In quadrant II
tan ∅ = 5 / (-3)
[tex]hyp^2 = 5^2 + (-3)^2\\hyp^2 =25 + 9 = 34\\hyp = \sqrt{34}[/tex]
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}[/tex]
[tex]sin \theta = \dfrac{5}{\sqrt{34} }[/tex]
Rationalizing
[tex]sin \theta = \dfrac{5\sqrt{34}}{{34} }[/tex]

Answer:
D
Step-by-step explanation:
A: The sum of Y and H is +. If the scale is correct, this is not true. Y is further away from 0 than H is. Suppose H = 5 and Y = -7. Then Y + H = 5 + -7 = - 2
B: E and Y area both minus. The minus signs cancel. Therefore the answer will be + B is wrong.
C: H>0 and E<0. A negative times a positive is a negative not a positive. C is wrong
D: A - H Suppose A = 2 and H = 5 . Then A - H = 2 - 5 which is - 3
This is your answer.
The reason is that H is further from the 0 than A is.

Find the sum of the first 32 terms of the arithmetic sequence 24, 20, 16,
Answer:
[tex]S_{32}[/tex] = - 1216
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 24 and d = a₂ - a₁ = 20 - 24 = - 4 , then
[tex]S_{32}[/tex] = [tex]\frac{32}{2}[/tex] [ (2 × 24) + (31 × - 4) ]
= 16(48 - 124)
= 16 × - 76
= - 1216

Answer:
2384
Step-by-step explanation:
40x50=2000
40x24/2=384
2000+384=2384
Answer:
2384
Step-by-step explanation:
1. Approach
To solve for the area of the given figure, divide the figure up into two parts. This will ensure that one can find the area of each individual part, and then add the two resulting areas up to find the total area of the figure. One can split this figure into a rectangle, and a triangle.
2.Find the area of the rectangle
The rectangle will have the following dimensions,
(40) x (50)
To find the area of a rectangle, one will use the following formula,
(length) * (width) = (area)
Therefore, the area is the following,
(40) * (50) = 2000
3.Area of the triangle
3a. Approach
To find the area of a triangle, one will use Heron's formula. Herons' formula states the following,
[tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where (s) is the semi-perimeter or half of the perimeter, and (a), (b), and (c) are the sides of the triangle. This requires that one knows all of the sides of the triangle.
3b. Find the unknown side and semi-perimeter
It is given that the triangle is right indicated by a box around one of the angles), thus one can use the Pythagorean theorem to find the length of the unknown side. The Pythagorean theorem states the following,
[tex]a^2+b^2=c^2[/tex]
Where (a) and (b) represent the legs, the sides adjacent (next to) the right angle. Moreover, (c) represents the hypotenuse or the side opposite the right angle. Substitute in the given values and solve for (b),
[tex](40)^2=(24)^2+(b)^2\\[/tex]
Simplify,
[tex]1600=576+b^2[/tex]
Inverse operations,
[tex]1024=b^2\\\sqrt{1024}=b\\32=b[/tex]
Add up all of the sides of the triangle and divide by (2) to fin the semi-perimeter,
[tex]\frac{a+b+c}{2}\\\\=\frac{20+24+32}{2}\\\\=48[/tex]
3c. Find the area of the triangle
Substitute into Heron's formula,
[tex]\sqrt{s(s-a)(s-b)(s-c)}\\\\=\sqrt{48(48-32)(48-40)(48-24)}\\\\=\sqrt{48(16)(8)(24)}\\\\=\sqrt{147456}\\\\=384[/tex]
Add the area of the rectangle and triangle together to find the answer,
384 + 2000
= 2384

Answer:
A line that is perpendicular to y=2/5x-5 must have a slope of -5/2, but a line parallel to line y=5/2x+6 must have a slope of 5/2, and these slopes do not match up.
Explanation:
In order for a line to be parallel to another line, they must have the same slope. In order for a line to be perpendicular to another line, their slopes must be opposite reciprocals (meaning that when they are multiplied, the product is -1). From here you can find what slope the line must have to perpendicular or parallel to another line, and then you can see that the answers to not match up to be the same line!

Solve -7g - 2 = - 30. Show your steps.
Answer:
g = 4
Step-by-step explanation:
-7g - 2 = -30
Add 2 to both sides to get:
-7g -2+2 = -30+2
which is equal to:
-7g = -28
now divide both sides by -7 to get the value of g which is:
g = -28 / - 7
--> g = 4
Answer:
g = 4
Step-by-step explanation:
First you can add 2 to both sides to isolate the x term:
-7g -2 = -30
+2 +2
-7g = -28
Now, you can divide by -7 both sides to find g,
-7g = -28
÷ -7 ÷ -7
g = 4

Which model best represents the data?
y = 47(1.191)x
y = 34(1.204)x
y = 26.9x – 1.3
y = 27x – 4
Answer:
Y=26.9x-1.3is the answer
Step-by-step explanation:
The best model represents y = 26.9x – 1.3
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
As, the data given about productivity is well defined by y = 26.9x – 1.3
As, we have 4 functions so by putting the values we get
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
So, the most accurate is (C)y = 26.9x – 1.3.
