If the first 2 sides of a triangle are 6 cm and 4 cm, which of the following are possibilities for the other side? Choose all that apply.
2.5 cm
2 cm
1 cm
4 cm
Answer:
2.5cm and 4cmStep-by-step explanation:
According to Triangle Inequality Property:
Measurement of any two sides of the triangle should be greater than the third side
So,
For 2.5,
6 + 4 = 10 > 2.5
4 + 2.5 = 6.5 > 6
6 + 2.5 = 8.5 > 4
For 4,
6 + 4 = 10 > 4
4 + 6 = 10 > 4
4 + 4 = 8 > 6
While for 1 and 2,
4 + 1 = 5 < 6
and
4 + 2 = 6 = 6
Hence,
Only 2.5 and 4 are the possible measurements.

Use the function f(x) = 2 sin x-1 to identify the following.
A. amplitude =
B. period =
C. midline=
Answer:
See below for answers
Step-by-step explanation:
Do you mean [tex]f(x)=2sin(x-1)[/tex] or [tex]f(x)=2sin(x) -1[/tex]?
Use the formula [tex]f(x)=asin(bx+c)+d[/tex] where [tex]|a|[/tex] is the amplitude, [tex]-\frac{c}{b}[/tex] is the phase shift, [tex]d[/tex] is the vertical shift, and the period is [tex]\frac{2\pi}{|b|}[/tex].
Assuming your first case is true, the amplitude would be [tex]|a|=|2|=2[/tex], your period is [tex]\frac{2\pi}{|1|}=2\pi[/tex], and your midline/vertical shift is [tex]d=0[/tex].
Assuming your second case is true, everything but the vertical shift stays the same. It would be [tex]d=-1[/tex] in this case.

7x + 2y - 3 = 0 in slope intercept form.
Answer:
y=(-7/2)x+3
Step-by-step explanation:
7x+2y-3=0
7x+2y=3
2y=-7x+3
y=(-7/2)x+3
Answer:
y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
7x + 2y - 3 = 0 ( subtract 7x - 3 from both sides )
2y = - 7x + 3 ( divide each term by 2 )
y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← in slope- intercept form

7x + 3y = -18?
Oy=7/3x +1
Oy= 3/7 x + 5
Oy= - 3/7 x + 2
Oy= -7/3 x + 6
Answer: y=3/7x + 5
Step-by-step explanation:
The solution is, y = 3/7 x + 5, equation represents a line which is perpendicular to the line 7x + 3y = -18.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
we know that,
In order to determine the equation with a line perpendicular to the given equation, consider that for two perpendicular lines, the relation in between their slopes is:
m1 = -1/(m2)
where m1 and m2 are the slopes of the lines.
Write the given equation in slope-intercept form to identify the slope m1, as follow:
7x + 3y = -18 subtract 7x both sides
3y = - 7x - 18 divide by 3 both sides
y = -7/3 x - 6
remind that the general form of the equation of a line can be written as follow:
y = mx + b
where m is the slope. Based on the expression for y = -7/3 x - 6, you have
m1 = -7/3
then, calculate m2:
m2 = -1/(m1)
m2 = -1/(-7/3)
m2 = 3/7
Hence, it is necessary that the perpendicular line has a positive slope of 3/7.
From the given answer choices, you can notice that the only option with the required slope is:
y = 3/7 x + 5

These are the cost and revenue functions for a line of 24-pound bags of dog food sold by a large distributor:
R(x) = -31.72x2 + 2,030x
C(x) = -126.96x + 26,391
The maximum profit of $ Blank
can be made when the selling price of the dog food is set to $ Blank
per bag.
there are two answers
Answer:
$10,277.32
Step-by-step explanation:
Given the revenue and cost function
R(x) = -31.72x^2 + 2,030x
C(x) = -126.96x + 26,391
The profit function is expressed as;
P(x) = R(x) - C(x)
P(x) = -31.72x^2 + 2,030x-(-126.96x + 26,391)
P(x) = -31.72x^2 + 2,030x+126.96x - 26,391
P(x) = -31.72x^2 + 2,030x+126.96x - 26,391
P(x) = -31.72x^2 + 2,156.96x - 26,391
To have maximum profit, d
The maximum profit dP/dx = 0
dP/dx = -63.44x+2156.96
-63.44x+2156.96=0
63.44x = 2156.96
X = 2156.96/63.44
x = 34
Get the profit
P(34) = -31.72(34)² + 2,156.96(34)- 26,391
P(34) = -36668.32+73336.64-26391
P(34) = 10,277.32
Hence the maximum profit that can be made is $10,277.32

PLEASE HELP ME A soccer field is bordered on three sides by a parking lot of width x. The total length of the field and parking lot is 300 m, and the total width is 200 m.
The area of the field is 30.000 m². How wide is the parking lot?
Answer:
Step-by-step explanation:
Assuming the parking lot is along both widths of the field and only once along the length:
the length is (300 - 2x)
the width is (200 -x)
the area is (300-2x)(200-x) = 30000
60000 -300x - 400x +2x^2 = 30000
2x^2 -700x + 30000 = 0
x^2 - 350x + 15000 = 0
(x - 300 )(x - 50 ) = 0
x = 300 or x=50
x=300 results in negative measures.
the parking lot is x=50 wide
the length of the field is 200, the width of the field is 150

En una tienda en la que todo está rebajado el 15% he comprado un pantalón por el que he pagado 102 €. ¿Cuál era el precio antes de la rebaja?
Answer:
120 euros
Step-by-step explanation:
X= 100% del precio (antes de la rebaja)
Pagaste el 85% pues habia descuento del 15%
85%--------------102
100%---------------x
CROSS MULTIPLICATION
85X = 10200
Divide cada parte por 85
x= 120
Teniendo en cuenta la definición de descuento, el precio antes de la rebaja era 120 €.
En una operación de descuento, el valor que se paga después de haberle practicado el descuento se denomina “valor actual”.
Recordando que el porcentaje representa una parte del total, el valor actual se puede calcular multiplicando el porcentaje a descontar por el precio original, al cual luego se divide por cien. Finalmente, se resta al precio original este valor de descuento calculado. De esta manera se averigua el precio de venta.
Entonces, sea el precio original del producto p. Por lo que el descuento del precio original será:
15% de p= (15×p) ÷10
Sabiendo que se ha pagado 102 € por el pantalón, entonces:
p - (15×p) ÷10 = 102
Resolviendo
p - 0,15×p= 102
0,85×p= 102
p= 102÷0.85
p= 120
Finalmente, el precio antes de la rebaja era 120 €.

Kelly had a part-time job last year. She paid the state $234 in income tax. The state income tax rate is 5.2%. How much did Kelly earn?
Answer:
$4500
Step-by-step explanation:
Find how much she earned by dividing 234 by 0.052
234/0.052
= 4500
So, she earned $4500
Answer: see below
Step-by-step explanation:
Divide 234 by 5.2 to get one percent of her earnings, $45.
Multiply 45 by 100 to get 100% of her earnings, $4,500
If it asking for the gross earnings, leave it at $4,500
If it is asking for net earnings, subtract 234 from 4500 to get $4,266

The given hypothesis of the number of Americans that vote in the presidential election is;
Hypothesis; At most 60% of Americans vote in the presidential elections
Therefore, the hypothesis states that the percentage of Americans that vote in the presidential ≤ 60%
The given hypothesis is the null hypothesis due to the presence of one of the operators ≤, ≥, or =

Answer:
1. a = 16, b = 14
2. a = 16.5, b = 23.2
3. a = 7.25, b = 6.5
4. a = 8.4, b = 20
Step-by-step explanation:
Problem One:
2a + 6 = 3a - 10
6 = a - 10
16 = a
6b - 3 = 81
6b = 84
b = 14
Problem Two:
4a - 8 + 8a - 10 = 180
12a - 18 = 180
12a = 198
a = 16.5
8(16.5) - 10 = 5b + 6
122 = 5b + 6
116 = 5b
b = 23.2
Problem Three:
5b - 7 = 3b + 6
2b - 7 = 6
2b = 13
b = 6.5
2a = 3(6.5) - 5
2a = 14.5
a = 7.25
Problem Four:
3a + 1.8 = 4a - 6.6
1.8 = a - 6.6
