Step-by-step explanation:
1. The midpoint formula says the coordinates of the midpoint are the average of the endpoints.
x = (x₁ + x₂) / 2
y = (y₁ + y₂) / 2
I'll do #2 and #3 as examples.
2. x = (-4 + 10) / 2 = 3
y = (6 + -10) / 2 = -2
So the midpoint is (3, -2).
3. x = (-3 + -6.5) / 2 = -4.75
y = (-8 + -4.5) / 2 = -6.25
So the midpoint is (-4.75, -6.25).
work out 7 x 10 to the power of five /2 x 10 to the power of 2
Answer: 3500
Step-by-step explanation:
7 x 10 to the 5th power = 700000
2 x 10 squared = 200
700000/200 = 3500
Answer:
4201750
Step-by-step explanation:
7*10^5/2*10^2
7*10=70
2*10=20
70^5/20^2
70^5 =1680700000
20^2=400
1680700000/400=4201750

How do I write an equation in point-slope form for m=-3 (-2,-1) ?
Answer:
y + 1 = -3(x + 2)
Step-by-step explanation:
Point-slope form is y - y1 = m(x - x1)
m= -3 (-2, -1)
Plug -3 in for the m in the equation, -2 in for x1, and -1 in for y1
y - (-1) = -3(x - (-2))
Subtracting negatives will make them positive
y + 1 = -3(x + 2)
This is the point-slope form, continuing to solve for y will give the y-intercept form.
Y-intercept Form:
y = -3x - 7
A baseball player swings at the ball 56 times over a season and hits 16 times.
What is the ratio of hits to misses?
Answer:
2:5.
Step-by-step explanation:
Number of misses = 56 - 16 = 40.
Ratio = 16:40
- which simplifies to (16/8) : (40 / 8)
= 2:5.
En la casa de Juan, van a pedir pizza para la comida, pero cuando la van a pedir se dan cuenta que deben pedirla por perímetro o área de la misma. La mamá dice que es más grande la de perímetro de 100cm y el papá dice que es más la de área de 100cm². ¿Cuál tiene la razón? *
Responder:
La pizza con un perímetro de 100 cm es más grande ¿verdad?
Explicación paso a paso:
Deja que la pizza tenga forma circular.
Sea el área de la pizza = πd² / 4 y;
Perímetro de la pizza = πd
d es el diámetro de la pizza
Si la madre dice que el que tiene un perímetro de 100 cm es más grande, para estar seguros necesitamos obtener el diámetro de la pizza. La de mayor diámetro será la pizza más grande.
P = 100cm
100 = πd
d = 100 / π
d = 100 / 3,14
d = 31,85 cm
El diámetro de la pizza mamá es de 31,85 cm.
Si el padre dice que el que tiene un área de 100 cm² es más grande, obtengamos también el diámetro para estar seguros.
A = πd² / 4
100 = πd² / 4
400 = πd²
d² = 400 / π
d² = 400 / 3,14
d² = 127,39
d = √127,39
d = 11,29 cm
Por lo tanto, el diámetro de la pizza padre es de 11,29 cm.
Dado que el diámetro de la pizza madre es mayor que el de esa, la pizza con un perímetro de 100 cm es más grande, lo que demuestra que la madre tiene razón.

What values of a and b make this equation true?
(4 + ✓–49) – 2(/(-4)2 + V–324) = a + bi
Answer:
-4 , -29
Step-by-step explanation:
The values of a and b that make the equation true are -28 and -9, respectively
How to determine the true values of a and b?The equation is given as:
(4 + √-49) – 2((-4)² + √–324) = a + bi
Evaluate the exponents
(4 + 7i) – 2(16 + 18i) = a + bi
Expand the bracket
4 + 7i – 32 - 16i = a + bi
Collect like terms
4 – 32 + 7i - 16i = a + bi
Evaluate like terms
-28 -9i = a + bi
By comparison, we have:
a = -28 and b = -9
Hence, the values of a and b that make the equation true are -28 and -9, respectively
