The endpoints of the longest chord on a circle are (4,5.5) and (4,10.5)

Mathematics

zaharov [31]3 years ago

Answer and Step-by-step explanation:

The longest chord on the circle is the diameter, and the center of the circle is the midpoint of the diameter.

Use the midpoint formula to find the center

the x-coordinates are the same, so you can just subtract the y-coordinates to find the radius.

10.5 - 8 = 2.5

The equation of the circle is (x - h)² + (y - k)² = r² where r is the radius and (h, k) is the center.

(x - 4)² + (y - 8)² = 6.25

Marsha Waite borrows $7,000 and agrees to pay it back in 2 years if the simple interest rate is 15%
I am Lyosha [343]

Answer:

Marsha must pay in 2 years \$9,100

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A  is the amount of money to pay

P is amount of money borrowed  

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=2\ years\\ P=\$7,000\\ A=?\\r=15\%=15/100=0.15

substitute in the formula above

A=7,000(1+0.15*2)

A=7,000(1+0.30)

A=7,000(1.30)

A=\$9,100

therefore

Marsha must pay in 2 years \$9,100

Carla trabaja en el área de compras de una empresa que tiene 8 sucursales a lo largo de Chile. A pedido de su jefe necesita comp
Anvisha [2.4K]

Answer:

Los gastos totales en los que incurre Carla = (36x + 28y + 3z) pesos

Step-by-step explanation:

A partir de la pregunta, a continuación se proporciona la cantidad de elementos necesarios:

21 lápices, 8 carpetas, 3 broches, 10 resaltadores, 6 blocs de notas adhesivas y 9 rotuladores.

Los precios de cada artículo se dan a continuación

Precio de cada lápiz = x pesos

Precio de cada carpeta = y pesos

Precio de cada broche = z pesos

El precio de cada resaltador es el doble que el de cada carpeta

= 2 × y pesos

= 2y pesos

El precio de cada barra de notas adhesivas es el doble del precio de cada lápiz

= 2 × x pesos

= 2x pesos

El precio de cada marcador (bolígrafo) es el triple del precio de cada lápiz.

= 3 × x pesos

= 3x pesos

Indique el gasto total en el que incurrirá Carla.

Los gastos totales en los que incurrirá Carla =

(21 × x pesos) + (8 × y pesos) + (3 × z pesos) + (10 × 2y pesos) + (6 × x pesos) + (9 × x pesos)

= (21x + 8y + 3z + 20y + 6x + 9x) pesos

Recopilar términos similares

= (21x + 6x + 9x + 8y + 20y + 3z) pesos

= (36x + 28y + 3z) pesos

Por lo tanto, los gastos totales en los que incurre Carla = (36x + 28y + 3z) pesos
