Step-by-step explanation:
The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct?
Answer:
Helena is correct.
Step-by-step explanation:
The slope intersept form of the line is
y = m x + c
where, m is the slope and c is the intersept.
The point slope form of the equation is
[tex]y - y'= \frac{y''-y'}{x''-x'}\times (x-x')[/tex]
So, if there are two points are given, the equation of line is found by the point slope form.
So, Helena is correct.
A 2 kg hammer is used to nail a 0.002 kg nail with a force of 10 N. How much force is applied to the hammer?
Answer:
19.62N
Step-by-step explanation:
Given data
Mass =2kg
Force =10N
The applied force is
F=mg
F=2*9.81
F=19.62N
Hence the applied force is 19.62N

Find the length of AB.
A
O 140°
8 m
B
Round your answer to the nearest hundredth.
ÁB = [ ? ]m
:)
Answer:
19.55m
Step-by-step explanation:
We solve the above question using the formula for Arc Length
The formula of Arc length when central angle is given in degrees = Length of AB
= θ/360 × 2πr
Central angle = θ = 140°
Radius = r = 8m
Hence,
Length AB = 140/360 × 2 × π × 8
= 19.547687622 m
Approximately to the nearest hundredth, the length of AB = 19.55m

If P = (3,2), find the image
of P under the following rotation.
90° counterclockwise about the origin
([?], [])
Enter the number that belongs in
the green box
Enter
Answer:
(-2, 3)
Step-by-step explanation:
Think of this in the future:
Counter-clockwise rotations:
90-degree --> (x,y) = (-y,x) ex. (3,2) --> (-2,3)
180-degree --> (x,y) = (-x,-y) ex. (3,2) --> (-3, -2)
270 degree --> (x,y) = (y,-x) ex. (3,2) --> (2, -3)
Clockwise rotations:
90-degree --> (x,y) = (y, -x) ex. (3,2) --> (2, -3)
180-degree --> (x,y) = (-x,-y) ex. (3,2) --> (-3,-2)
270-degree --> (x,y) = (-y, x) ex. (3,2) --> (-2,3)

Step-by-step explanation:
2(5x + 3) + 2 = 10x + 6
A-one solution
B-infinitely many solutions
c-no solution
Answer:
C
Step-by-step explanation:
Given
2(5x + 3) + 2 = 10x + 6 ← distribute and simplify left side
10x + 6 + 2 = 10x + 6
10x + 8 = 10x + 6 ( subtract 6 from both sides )
10x + 2 = 10x ( subtract 10x from both sides )
2 = 0 ← not possible
This indicates the equation has no solution
Answer:
no solutions
Step-by-step explanation:
2(5x + 3) + 2 = 10x + 6
* solve for x *
step 1 distribute the 2 to 5x and 3
2 * 5x = 10x
2*3=6
we now have 10x + 6 + 2 = 10x + 6
step 2 combine like terms
6 + 2 = 8
we now have 10x + 8 = 10x + 6
step 3 subtract 10x from each side
10x-10x=0
10x-10x=0
we're left with 8 = 6
8 is not equal to 6 meaning that there are no solutions to the equation

Because the variable m does not appear in Ax + By = C, equations in this form make it impossible to determine the line's slope m. If the statement does not make sense, then how can you find m and what would it be? Show your work.
Answer:
Step-by-step explanation:
The statetement does not make sense because we can rewrite the equation of the line in the slope intercept form
1) add -Ax at both members
Ax + By - Ax = -Ax + C
By = -Ax + C
2) divide both members by B (assuming that its value is not 0)
y = (-A/B) x + C/B
the slope of the line is the therm that multiply x, so
m = -A/B

Jason has 208 baseball cards. This is 52 less than the number of cards that Robert has.
Which equation below best represents this scenario?
A) R+ 208= 52
B) R- 52 = 208
C) 52 - R = 208
D) 208 - 52 = R
Answer:
B) R - 52 = 208
Step-by-step explanation:
Robert has 52 more cards than Jason, who has 208, so Robert has 208 + 52 cards. This can be turned into:
R = 208 + 52
then subtract 52 from both sides:
R - 52 = 208 + 52 - 52
R - 52 = 208
and that's the answer

Determine the equation of the circle graphed below.
Answer:
[tex](x-4)^2+(y+3)^2=20[/tex]
Step-by-step explanation:
The equation of a circle with center [tex](h,k)[/tex] and radius [tex]r[/tex] is given by [tex](x-h)^2+(y-k)^2=r^2[/tex].
What we know:
Center at [tex](4,-3)[/tex]To find the radius, we can use the distance formula. For points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex], the distance between them is [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex].
Let
[tex](x_1,y_1)\implies (-4, -3),\\(x_2,y_2)\implies (8,-1)[/tex]
[tex]r=\sqrt{(8-4)^2+(-1-(-3))^2},\\r=\sqrt{4^2+2^2},\\r=\sqrt{20}=2\sqrt{5}[/tex]
Thus, the equation of this circle is
[tex](x-4)^2+(y-(-3))^2=\sqrt{20}^2,\\\boxed{(x-4)^2+(y+3)^2=20}[/tex]

True or false question. In Standard form, the number 3.5 *10^4 is 3,500.
Answer: False
Step-by-step explanation:
10^4=10000. 10000*3,5=35000.
Answer:
No, you missed a zero.
Step-by-step explanation:
In the given case, as we have the number as
3.5 × 10^4, we need to move decimal digit to the right by three points. For this, let us write 3.5 as 3.50000 and moving decimal point four points to right means
35000.0
Hence in standard notation
3.5 × 10^4=35,000

can you please help? f(x)=x^2 what is g(x)?
Answer:
D
Step-by-step explanation:
g(x) will be -x^2-3. The minus in front of the x makes the graph flip upside down, and the "-3" indicates its position on the y-axis. Hope this helps!!
Answer: Choice D. g(x) = -x^2-3
==============================================
Explanation:
Start with the curve y = x^2.
Reflect it over the horizontal x axis to get y = -x^2
Then shift everything down 3 units to arrive at g(x) = -x^2-3
You can use a tool like Desmos or GeoGebra or anything similar to help verify this.

PLEASE HELP MEEEE:((
Answer:
g(x)=[tex](3x)^{2}[/tex]
Step-by-step explanation:
In this graph g(x) will be equal to g(x)=[tex](3x)^{2}[/tex]. Multiplying a squared variable will close the parabola together, but multiplying the variable itself and then calculating the square will exponentially close the parabola. Without the parenthesis x would be substituted for 1, 1 squared is 1 and multiplied by 3 would be 3. Therefore, giving you a coordinate of (1,3). With parenthesis that would be 3 times greater which would give you a coordinate of (1,9) as can be seen in the graph attached below.

El angulo de elevacion del sol es de 29°12'35''. Calcular la longitud de la sombra proyectada por un hombre de 1,75m de estatura.
Respuesta:
3,59 metros
Explicación paso a paso:
Conversión del ángulo de elevación a grados;
29 ° 12 '35 "
= 29 ° + 12 '/ 60 + 35 "/ 3600
= 29,20972 °
Resolviendo el triángulo de solución adjunto:
La longitud de la sombra se puede obtener utilizando la relación trigonométrica;
Sin θ = opuesto / hipoteno
Sin 29.20972 = 1.75 / sombra
Sombra = 1.75 / Sin 29.20972
Longitud de la sombra = 3,59 m
Which of these answer choices can find the width
A. Width = (70 yd + 40 yd) /2
B. Width = (70 yd + 40 yd) /4
C. Width = (70 yd - 40 yd) /2
D.width = (70 yd - 40 yd) /4
Answer:
C
Step-by-step explanation:
2 (20)=40
70-40=30
30/2 = 15 actual width of both sides
