Answers

Answer 1
X1= -9, X2= 5 I hope I helped
Answer 2

Answer:

x = -9 and x = 5

Step-by-step explanation:

[tex] {(x + 2)}^{2} + 1 = 50[/tex]

[tex] = {x}^{2} + 4x + 4 + 1 = 50[/tex]

[tex] = {x}^{2} + 4x + 5 = 50[/tex]

[tex] = {x}^{2} + 4x + 5 - 50 = 0[/tex]

[tex] = {x}^{2} + 9x - 5x - 45 = 0[/tex]

[tex] = x \times (x + 9) - 5(x + 9) = 0[/tex]

[tex] = (x + 9) \times (x - 5) = 0[/tex]

[tex] = x + 9 = 0[/tex]

[tex] x - 5 = 0[/tex]

[tex] = x = - 9[/tex]

[tex]x = 5[/tex]

A line passes through the points (–6, –7) and (–3, 1). What is its equation in slope-intercept form?

Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

y = 8/3(x) + 9

Step-by-step explanation:

The general equation of a straight line is slope intercept form is;

y = mx + b

where m is the slope and b is the y-intercept

To get the slope, we use the slope equation

we have this as:

m = (y2-y1)/(x2-x1)

(x1,y1) = (-6,-7)

(x2,y2) = (-3,1)

m = (1+7)/(-3 + 6) = 8/3

so we have the equation as;

y = 8/3(x) + b

to get the value of b, we make use of any of the two points

We substitute the coordinates of the two points into the equation

Let us use the point (-3,1)

Thus;

1 = 8/3(-3) + b

1 = -8 + b

b = 1 + 8

b = 9

So the full equation is;

y = 8/3(x) + 9

Please answer the question below (ABOUT VECTORS AND MAGNITUDE)

Answers

(a) v appears to have a fixed direction along the positive x-axis. If ||u|| = 150 N, ||v|| = 220 N, then when θ = 30°, you have

u = (150 N) (cos(30°) i + sin(30°) j ) ≈ (129.904 i + 75 j ) N

v = (220 N) (cos(0°) i + sin(0°) j ) = (220 i ) N

(i and j are the unit vectors in the positive x and y directions)

and their sum is

u + v ≈ (349.904 i + 75 j ) N

with magnitude

||u + v|| ≈ √((349.904)² + (75)²) N ≈ 357.851 N ≈ 357.9 N

and at angle φ made with the positive x-axis such that

tan(φ) ≈ (75 N) / (349.904 N)   →   φ ≈ 12.098° ≈ 12.1°

(b) Letting θ vary from 0° to 180° would make v a function of θ :

u = (150 N) (cos(θ) i + sin(θ) j ) = (150 cos(θ) i + 150 sin(θ) j ) N

Then

u + v = ((220 + 150 cos(θ)) i + (150 sin(θ)) j ) N

→   M = ||u + v|| = √((220 + 150 cos(θ))² + (150 sin(θ))²) N

M = √(48,400 + 66,000 cos(θ) + 22,500 cos²(θ) + 22,500 sin²(θ)) N

M = 10 √(709 + 660 cos(θ)) N

(c) As a function of θ, u + v makes an angle α with the positive x-axis such that

tan(α) = (150 sin(θ) / (220 + 150 cos(θ))

→   α = tan⁻¹((15 sin(θ) / (22 + 15 cos(θ)))

(d) Filling in the table is just a matter of evaluating M and α for each of the given angles θ. For example, when θ = 0°,

M = 10 √(709 + 660 cos(0°)) N = 370 N

α = tan⁻¹((15 sin(0°) / (22 + 15 cos(0°))) =

When θ = 30°, you get the same result as in part (a).

When θ = 60°,

M = 10 √(709 + 660 cos(60°)) N ≈ 323.3 N

α = tan⁻¹((15 sin(60°) / (22 + 15 cos(60°))) = 23.8°

and so on.

if the ratio of type O to non-type O donors at a blood drive was 37:43. how many would be type O out of 300 donors? will try and mark brainliest . please show the work as well

Answers

Answer:

Step-by-step explanation:

Proportion of type O donors = 37/(37+43) = 37/80

300 × 37/80 = 138.75

139 donors out of 300 are type O.

A ratio shows us the number of times a number contains another number. The number of type O donors out of 300 is 139.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that the ratio of type O to non-type O donors at a blood drive was 37:43. Therefore, the number of type O blood donors be represented by 37x and the number of non-type O blood donors be represented by 43x.

Now, the sum of type and non-type O donor is 300. Therefore, we can write,

37x + 43x = 300

80x = 300

x = 3.75

Further, the Number of type O donors out of 300 can be written as,

Number of type O donors out of 300 = 37x = 37(3.75) = 138.75 ≈ 139

Hence, the number of type O donors out of 300 is 139.

Cual es el mejor estimado de la solucion de lsistema de ecuciones lineales graficadas. y=4x-4 2x+y=5

Answers

Answer:

x = 1.5, y = 2

Step-by-step explanation:

Cuando tenemos un sistema de ecuaciones lineales, para resolverlo gráficamente simplemente debemos graficar ambas líneas y ver en que punto las líneas se interceptan.

En este caso, tenemos las líneas:

y = 4*x - 4

2*x + y = 5

El primer paso puede ser escribir ambas líneas en forma estándar, así será más fácil graficarlas.

Para ello, aislamos y en ambas ecuaciones:

y = 4*x - 4

y = 5 - 2*x

Ahora que tenemos ambas líneas debemos graficarlas en un mismo eje de coordenadas, y buscar el punto en donde ambas líneas se interceptan.

Un gráfico de este sistema se puede ver abajo:

Viendo el gráfico, podemos estimar que la solución del sistema es el punto:

(1.5, 2)

Es decir, la solución es:

x = 1.5

y = 2

Solamente para ser completos, también podemos resolver el sistema analíticamente y ver si la solución que encontramos gráficamente es aceptable.

Para ello escribimos el sistema:

y = 4*x - 4

y = 5 - 2*x

Como y esta aislada en ambas ecuaciones, tendremos:

4*x - 4 = y = 5 - 2*x

4*x - 4 = 5 - 2*x

Ahora podemos resolver esto para x.

4*x + 2*x = 5 + 4

6*x = 9

x = 9/6 = 3/2 = 1.5

Remplazando este valor de x en cualquiera de las dos líneas obtendremos el valor de y de la solución:

y = 4*x - 4 = 4*1.5 - 4 = 6 - 4 = 2

Así probamos analíticamente que la solución es x = 1.5, y = 2.

Joe has 6 frogs, 8 hamsters, 9 goldfish, and 3 snakes. What is the ratio of Joe's frogs and snakes to hamsters?

Answers

Answer:

9:8

Step-by-step explanation:

According to the word problem, Joe has 6 frogs, 8 hamsters, 9 goldfish, and 3 snakes.

The question is asking the ratio of Joe's frogs AND snakes TO hamsters.

To find out the ratio of frogs and snakes, add how many frogs there are to how many snakes there are.

6 + 3 = 9.

The last part of the equation should be obvious.

There are 8 hamsters.

Therefore, the ratio of Joe's frogs and snakes to hamsters is 9:8.
