Write the equation of the line parallel to x = 7 which passes through (0, 1).
Answer:
x = 0
Step-by-step explanation:
If the line is parallel to x = 7, it will also be a vertical line.
Vertical lines will only have one possible x-value, and since the line passes through (0, 1), this means the vertical line goes through the x value 0.
The equation of the line will be x = 0

Center (-10, -4), Point on Circle: (4,2)
h=
k=
r^2=
Fill in the parenthesis for the equation of the circle:
(Blank 1)² +(Blank 2)²= (Blank 3)
*Just type what you would write in the parentheses with no spaces
Answer:
(x + 10)² + (y + 4)² = 232Step-by-step explanation:
Given Center = (-10, -4)Point on circle = (4, 2)To find The equation of circleSolutionRemember the standard equation of circle:
(x - h)² + (y - k)² = r², where (h, k) is the center and r is radiusWe have
h = -10, k = -4Use distance formula (Pythagorean theorem) to work out the length of the radius. We know that radius is the distance from the center to any point on the circle.
Here we are finding the distance between points (-10, -4) and (4, 2)
r² = (-10 - 4)² + (-4 - 2)² r² = 14² + 6²r² = 232So the equation is:
(x + 10)² + (y + 4)² = 2322. The area of a square is represented by the expression 16m2 - 40m + 25 square units. write the expression to represent the dimensions for each side. Explain what process you use. Justify your answer.
Answer:
Each side = 4m-5
Step-by-step explanation:
16m2 - 40m + 25
factor:
(4m - 5)(4m - 5)
Each side = 4m-5
Answer:
The expression for each side = 4m - 5.
Step-by-step explanation:
We need to factor the expression for the area. As the figure is a square both factors should be identical.
16m^2 - 40m + 25:
16m^2 and 25 are both perfect squares so looks like the factors are
(4m - 5)(4m - 5)
The signs are negative because the middle term is - 40m.
If we expand the factors we get:
4m*4m - 5*4m - 5*4m -5*-5
16m^2 - 20m - 20m + 25
= 16m^2 - 40m + 25 which is the original expression, so this confirms our result.

HELP FIND VALUE OF X
Answer:
72
Step-by-step explanation:
5a = 540 [ all interior angles r equal to 540 as "(n-2)x 180 (Interior ____________________________________________angle poperty )]
a= 540/5 = 108 (one interior angle)
x + a = 180 (linear pair)
x= 180 - a
x = 180 - 108 = 72
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Another way ::
Sum of Exterior angle = 360 (exterior angle property)
One exterior angle = x = 360 / 5 = 72 ( 360 by the number of sides )

Solve for x, rounding to the nearest hundredth.

Step-by-step explanation:
36 is the 5tf power of 2 so we can rewrite the equation as

Step-by-step explanation:
The function f(x)=2x^2+x+5 represents the number of jars of pickles, y in tens of jars, denise expects to sell x weeks after launching her online store. What is the average rate of change over the interval 1<\= x <\= 2? Pls help quick!
Answer:
The average rate of change is 7.
Step-by-step explanation:
We are given the function:
[tex]f(x)=2x^2+x+5[/tex]
Which represents the number of jars of pickles, y (in tens of jars), Denise expects to sell x weeks after launching her store.
We want to find the average rate of change over 1 ≤ x ≤ 2.
Essentially, we want to find the slope over f(1) and f(2).
Thus, first evaluate the two endpoints:
[tex]f(1)=2(1)^2+(1)+5=2+1+5=8[/tex]
And:
[tex]f(2)=2(2)^2+2+5=8+2+5=15[/tex]
This gives us the two points (1, 8) and (2, 15).
Then the average rate of change will be the slope between the two:
[tex]\displaystyle m=\frac{15-8}{2-1}=7[/tex]
With units, this means that over the first and second week, Denise sold on average 70 jars of pickles per week.
If 48% of the students in a certain college are female and there are 2,400 female students, how many students are male?
Answer:
2,600 male students
Step-by-step explanation:
[tex]\frac{2,400}{0.48} = 5,000[/tex]
There are 5,000 students in total.
Since 2,400 of them are female, the remaining students must be male.
5,000 - 2,400 = 2,600 male students
Se requiere saber la elevación x los 20.00 m de longitud , al construir una carretera , sabiendo que pendiente es de 5 %
Answer:
La elevación de la carretera es de aproximadamente 0.999 metros.
Step-by-step explanation:
Cuando se dice que la pendiente es de 5 %, se quiere decir que la tangente del ángulo de elevación de la carretera es de 0.05. Trigonométricamente hablando, podemos calcular el ángulo de la pendiente como sigue:
[tex]\theta = \tan^{-1} 0.05[/tex]
[tex]\theta \approx 2.862^{\circ}[/tex]
La elevación de la carretera se determina mediante la función seno:
[tex]\sin \theta = \frac{h}{l}[/tex] (1)
Donde:
[tex]h[/tex] - Elevación de la carretera, medida en metros.
[tex]l[/tex] - Longitud de la carretera, medida en metros.
Si sabemos que [tex]l = 20\,m[/tex] y [tex]\theta \approx 2.862^{\circ}[/tex], entonces la elevación de la carretera es:
[tex]h = l\cdot \sin \theta[/tex]
[tex]h \approx 0.999\,m[/tex]
La elevación de la carretera es de aproximadamente 0.999 metros.
Considerando la regla de tres, la elevación de la carretera es de 1 metro.
Regla de tresLa regla de tres es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos.
Es decir, lo que se pretende con ella es encontrar el cuarto término de una proporción conociendo los otros tres.
Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, la otra también (o cuando una magnitud disminuye, la otra también), se debe aplicar la regla de tres directa.
Para resolver una regla de tres directa se debe seguir la siguiente fórmula, siendo a, b y c datos conocidos yx la variable a calcular:
a ⇒ b
c ⇒ x
Por lo tanto: [tex]x=\frac{cxb}{a}[/tex]
ElevaciónUna pendiente de 5% indica que por cada 100 m de longitud hay 5 m de pendiente.
Entonces podes aplicar la siguiente regla de tres: si por cada 100 m de longitud hay 5 m de pendiente o elevación, por 20 metros de longitud ¿cuál será la pendiente?
[tex]elevacion=\frac{20 metrosx5 metros}{100 metros}[/tex]
elevación= 1 metro
La elevación de la carretera es de 1 metro.

Harold is designing a patio with congruent square concrete tiles. He has 72 tiles. Use grid paper to model all the possible rectangular patios Harold could build. Label the dimensions in units. Which patio has the greatest perimeter? The least perimeter?
Answer:
(a) The possible dimensions are:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
(b): Patio with greatest and the least perimeter
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9
Step-by-step explanation:
Given
[tex]Tiles = 72[/tex]
Solving (a): Possible rectangular models
To do this, we simply list out the possible factor pairs of 72.
So, we have:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
Solving (a): Models with the least and the greatest perimeter
Perimeter (P) is calculated using:
[tex]P = 2 * (L + W)[/tex]
So:
1 unit by 72 units;
[tex]P = 2 *(1 + 72) = 146 units[/tex]
2 units by 36 units;
[tex]P = 2 *(2 + 36) = 76 units[/tex]
3 units by 24 units;
[tex]P = 2 *(3 + 24) = 54 units[/tex]
4 units by 18 units;
[tex]P = 2 *(4 + 18) = 44 units[/tex]
6 units by 12 units;
[tex]P = 2 *(6 + 12) = 36 units[/tex]
8 units by 9 units
[tex]P = 2 *(8 + 9) = 34 units[/tex]
From the calculations above:
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9

First box: F (because we don't know the degrees Fahrenheit yet.
Second box: -62.1 (the degrees Celsius it tells us to find the equivalent of
Step-by-step explanation:
Solving the equation will go like this:
5/9(F - 32) = -62.1
multiply both sides by 9 to get rid of the fraction
5 (F - 32) = -558.9
divide both sides by 5
F - 32 = -111.78
add 32 to both sides
F = -79.78

Nick is on his school's swim team. During his 2-week winter break, he swims 30 laps each week to stay in shape. If each lap is 25 yards, how many feet does he swim during his winter break? Feet
Answer:
3900 feet
Step-by-step explanation:
Steps to answer this question
We are to convert yards to feet Multiply laps sum by two to determine the number of laps he swam in two weeksthen multiply figures gotten from 1 and 21 yard = 3 foot
25 yards = 25 x 3 = 65 foot
total yards swam = 30 x 2 = 60
60 x 65 = 3900
