Answer:
Step-by-step explanation:
We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:
[tex](3-0)^2+(6-0)^2=r^2[/tex] and
[tex]3^2+6^2=r^2[/tex] and
[tex]9+36=r^2[/tex]
Therefore, r-squared is 45, so the circle's equation in standard form is
[tex](x-0)^2+(y-0)^2=45[/tex] or more simply:
[tex]x^2+y^2=45[/tex]

Answer:
Option (2)
Step-by-step explanation:
Radius of the circular base of the cone = [tex]\frac{1}{2}(\text{Diameter of the circular base})[/tex]
Given in the picture,
Diameter of the circular base = 8 cm
Height of the cone = 6 cm
Therefore, radius of the cone = [tex]\frac{8}{2}[/tex]
= 4 cm

Answer:
Area = 20 square units
Step-by-step explanation:
=> We know that;
Base 1: 3 units
Base 2: 7 units
Height: 4 units
=> Now let's come up with a congruent base first:
[tex]\frac{(3 + 7)}{2}[/tex] = final base
10/2 = final base
5 = final base
=> Finally, Area of the trapezoid:
A = Final Base * Height

Find: P(Large or Blue)
Remember to reduce your answer.

Answers
This is the rigor answer
Answer:
7/10
Step-by-step explanation:
These must be marbles, right? There are 40 marbles all together (add all the numbers in the table).
P(Large or Blue) = P(Large) + P(Blue - P(Large and Blue)
= 25/40 + 20/40 - 17/40
= 28/40
=7/10
Note: P(Large) = 25/40 (the 25 comes from adding numbers in the "Large" column)
P(Blue) = 20/40 (the 20 comes from adding numbers in the "Blue" row)
P(Large and Blue) = 17/40 (that's the number in the Large column AND the Blue row)
The reason for the subtraction is this: if you just add numbers in the Large column and the Blue row, you end up adding the 17 Large AND Blue marbles twice. You want them to be counted only once.

Proceso porfas ♡
Answers
Answer:
C) Ascenso 6,34 m; Descenso 17,66 m
Step-by-step explanation:
La altitud máxima que recorre la pelota con respecto al suelo, h = 9 metros
La forma general de la ecuación de una parábola es y = a·x² + b·x + c
La velocidad vertical inicial de la pelota, [tex]u_y[/tex] = √(2·g·h)
∴ [tex]u_y[/tex] = √(2 × 9.81 × 9) ≈ 13.288
La velocidad vertical inicial de la pelota, [tex]u_y[/tex] ≈ 13.288 m/s
El tiempo de vuelo de la pelota = 2 × [tex]u_y[/tex]/g ≈ 2 × 13.288/9.81 = 2.709
El tiempo que tarda el balón en alcanzar los 7 metros sobre el suelo se indica de la siguiente manera;
s = [tex]u_y[/tex]·t + (1/2)·g·t²
∴ 7 ≈ 13.288·t - (1/2)×9.81×t²
13.288·t - (1/2)×9.81×t² - 7 ≈ 0
Factorizar con el uso de una calculadora gráfica da;
t ≈ 0.716 s, or t ≈1.993t
Dado que la velocidad horizontal es constante, verificamos entre las opciones dadas una que proporcione los valores de la velocidad horizontal, vₓ, tanto para el ascenso como para el descenso, es decir, para ambos valores de 't' de la siguiente manera;
De las opciones de respuesta dadas, la velocidad horizontal es aproximadamente constante para la única opción 'C', donde tenemos;
vₓ = 6.34/0.716 ≈ 8.85
vₓ = 17.66/1.993 ≈ 8.86
El rango horizontal, d = 8.85 × 2.709 ≈ 24
La distancia horizontal de la pelota durante el ascenso cuando la pelota alcanza una altura de 7 m = 6.34 m, durante el descenso, la distancia horizontal = 17.66 m
La ecuación de una parábola (la trayectoria de la pelota) se puede presentar de la siguiente manera;
y = a·(x - h)² + k
Dónde;
(h, k) = La coordenada del vértice
k = 9
En el origen, (x, y) = (0, 0)
Por lo tanto;
0 = a · (0 - h) ² + 9
a · h² = -9
En y = 7. x = 6.34
∴ 7 = a · (6.34 - h) ² + 9
a = -2 / ((6,34 - h) ²)
a = -2 / ((17,66 - h) ²)
(6,34 - h) ² = (17,66 - h) ²
h²-12,68 · h + 40,1956 = h² -35,32 · h +311,8756
h² -35,32 · h + 311,8756 - (h²-12,68 · h + 40,1956) = 0
-35,32 · h + 12,68 · h = 40,1956 - 311,8756
h = (40,1956 - 311,8756) / (- 35,32 + 12,68)
a = -2 / ((6,34 - 12) ²) ≈ -0,06243054601
La trayectoria de la pelota es y = -0.06243054601 · (x - 12) ² + 9
Por tanto, la mejor opción correcta que cumpla con los parámetros dados es la opción C) Ascenso 6,34 m; Descendencia 17.66 m.
A business owner wants to have the front window of her store painted and is considering two
artists for the job. Tiana has quoted a flat rate of $292 for the job. Denise's quote is $39 per
hour, plus $19 to cover the cost of materials. Depending on how long it takes Denise to paint
the window, these two could end up charging the same amount. How long would Denise have
to take? How much would it cost?
Answers
to get the answer:
i subtracted $19 from $292 to eliminate the
fee element because if you were to divide
$292 by $39 without the step, the hours would be incorrect and the price would be greater.
after subtracting i got $273
from there i divided $273 by $39 and got 7 (the amount of hours it would take)

Writing a linear equations
Answers
Answer:
y = -4x + 5
Step-by-step explanation:
Equation of the line can be written as y = mx + b (slope-intercept form)
Where m = slope and b = y-intercept of the line.
Let's find m and b of the line
Slope (m) using the points (1, 1) and (0, 5),
Slope (m) = change in y/change in x
m = (5 - 1)/(0 - 1) = 4/-1
m = -4
Find b:
b = the point where the line cuts the y-axis = 5 (y-intercept)
To write the equation substitute m = -4 and b = 5 into y = mx + b
y = -4x + 5
