Answer:

equation: 3x - 2 + 4x - 9 + 3x - 9 = 180 x = 20

Step-by-step explanation:

add all internal angles

∠H + ∠I + ∠J = 180

equation: 3x - 2 + 4x - 9 + 3x - 9 = 180

combine similar terms: 3x + 3x + 4x = 180 + 2 + 9 + 9

simplify: 10x = 200

divide 10 both sides: x = 20

X=20 I hope this helps

If an investment account starts with $3900, and grows with 2.1% interest, compounded continuously. How much is the account worth after 10 years? Round your answer to the nearest dollar. Do NOT round until you have calculated the final answer.

Answers

Answer:

If they are asking amount it is $4800.893013; $4800 (nearest dollar)

If they are asking the amount for interest is $900.8930129; $900 (nearest dollar)

Step-by-step explanation:

Compound interest Formula:

Amount = principle( 1+ rate/100)^n

Information from the question.

-So how you put it is the principle is $3900; the rate is 2.1%; the n is 10.

How to apply it?

- Just substitute in the values;

Amount=3900(1+2.1/100)^10

=4800.893013

~4800 ( nearest dollar)

》That is for amount.

Interest=4800.893013-3900

=900.893013

~900 ( nearest dollar)

》That is for interest.

Hope it helps!!!!:))

Answer:

Step-by-step explanation:

A=Pert=3900e(0.021)(10)≈4811.34

The account is worth $4811 after 10 years.

Answers

Given:

Triangle ABC with vertices A (-1, 4), B( -4, 1), and C(-1, 1) is reflected across the y-axis and then translated 4 units to the left to form triangle A’B’C’.

To find:

The coordinates of the vertices of triangle A’B’C’.

Solution:

If triangle ABC reflected across y-axis, then

[tex](x,y)\to (-x,y)[/tex]

[tex]A(-1,4)\to A_1(1,4)[/tex]

[tex]B(-4,1)\to B_1(4,1)[/tex]

[tex]C(-1,1)\to C_1(1,1)[/tex]

Coordinates of image after reflection across y-axis are [tex]A_1(1,4),B_1(4,1),C_1(1,1).[/tex]

Then triangle translated 4 units to the left to form triangle A’B’C’.

[tex](x,y)\to (x-4,y)[/tex]

[tex]A_1(1,4)\to A'(-3,4)[/tex]

[tex]B_1(4,1)\to B'(0,1)[/tex]

[tex]C_1(1,1)\to C'(-3,1)[/tex]

Therefore, the vertices of triangle A’B’C’ are A’ (-3, 4), B’ (0, 1), C’ (-3, 1).

Hence, the correct option is B.

6x^2-18x-18=6
CAN SOMEONE EXPLAIN PLS

Answers

Simplifying
6x2 + -18x + -18 = 6

Reorder the terms:
-18 + -18x + 6x2 = 6

Solving
-18 + -18x + 6x2 = 6

Solving for variable 'x'.

Reorder the terms:
-18 + -6 + -18x + 6x2 = 6 + -6

Combine like terms: -18 + -6 = -24
-24 + -18x + 6x2 = 6 + -6

Combine like terms: 6 + -6 = 0
-24 + -18x + 6x2 = 0

Factor out the Greatest Common Factor (GCF), '6'.
6(-4 + -3x + x2) = 0

Factor a trinomial.
6((-1 + -1x)(4 + -1x)) = 0
6(x^2-3x-3)=6
X^2-3x-3=1
X^2-3x-4=0

If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 194 feet

Answers

Complete Question

Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 220 feet and a standard deviation of 40 feet. Let X = distance in feet for a fly ball.

If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled fewer than 194 feet

Answer:

The value is [tex]P(X < 194 ) = 0.25785[/tex]

Step-by-step explanation:

From the question we are told that

  The mean is  [tex]\mu = 220 \ feet[/tex]

   The standard deviation is  [tex]\sigma = 40 \ feet[/tex]

   

Generally the probability that this ball traveled fewer than 194 feet is mathematically represented as

       [tex]P(X < 194 ) = P(\frac{X -\mu}{\sigma } < \frac{194 - 220}{40} )[/tex]

Generally   [tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]

         [tex]P(X < 194 ) = P(Z < -0.65 )[/tex]

From the z-table the probability of  [tex](Z < -0.65 )[/tex]

      [tex]P(Z < -0.65 ) = 0.25785[/tex]

So  

     [tex]P(X < 194 ) = 0.25785[/tex]

El lado de un rectángulo mide el tiple de su ancho, si el perímetro mide 96 cm ¿cuáles son sus dimensiones?

Answers

Answer:

Ancho 12 cm,  Largo 36 cm

Step-by-step explanation:

lamamos al ancho X y por tanto el largo será 3X

Como el perímetro es la suma de los 4 lados, tenemos la siguiente igualdad:

3X+3X+X+X=96 cm

8X=96 cm

X=96 cm/8

X=12 cm

El ancho mide 12 cm

Si el largo es el triple, entonces 3 x 12 = 36 cm
