Answer:

  D.  h(x) = 5x² +12x +9

Step-by-step explanation:

The final constants are mostly different, so you can simplify your work by just figuring that one.

  h(x) = g(x) -f(x)

  h(0) = g(0) -f(0) = -7 -(-16) = +9 . . . . . matches choice D

__

If you want to figure the whole expression ...

  h(x) = g(x) -f(x)

  h(x) = 12x² +7x -7 -(7x² -5x -16)

  h(x) = 12x² +7x -7 -7x² +5x +16

  h(x) = (12 -7)x² +(7 +5)x +(-7 +16)

  h(x) = 5x² +12x +9 . . . . . matches choice D

Answer: 6 years

Step-by-step explanation:

The formula for the Simple interest is given as: = PRT

Since we've been given some values already, we slot it into the formula and this will be:

Interest = PRT

78.12 = 217 × 6% × T

78.12 = 217 × 0.06 × T

78.12 = 13.02T

T = 78.12/13.02

T = 6

Time = 6 years

Answer:

coordinates are (x,y)->(x+6,y+2)

F's coordinate is (3,0)

using the coordinates we get (9,2)

Therefore the coordinates are (9,2)

The required coordinates of vertex H are (6,2).

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.

Given that triangles DFE and EHG are similar.

This means that the ratios of the lengths of their corresponding sides are equal.

As per the question, we have:

DF/FH = DE/EG

Since DF = 3 and DE = 1, we can set up the following equation to find the length of FH:

FH = EG × (DF/DE)

Substituting the known values, we get:

FH = EG × (3/1)

As we know that EG = 6, we can substitute this value to find that FH = 18.

The coordinates of F are (3,0) and the coordinates of H are (x,y), we can set up the following equations to find the values of x and y:

x - 3 = 18

y - 0 = 2

Solving these equations, we find that x = 21 and y = 2.

Thus, the coordinates of vertex H are (6,2).

Answer:

El ángulo de inclinación de la alberca es aproximadamente 12.407º.

Step-by-step explanation:

Puesto que conocemos la distancia horizontal ([tex]l[/tex]) y la variación en la profundidad ([tex]h[/tex]) de la alberca, en metros, podemos emplear la siguiente razón trigonométrica para calcular el ángulo de inclinación de la alberca ([tex]\alpha[/tex]), en grados sexagesimales:

[tex]\alpha = \tan^{-1}\left(\frac{h}{l} \right)[/tex] (1)

Si sabemos que [tex]l = 10\,m[/tex] y [tex]h = 2.20\,m[/tex], entonces el ángulo de inclinación de la alberca es:

Answer:

yes, but there is a better way

Step-by-step explanation:

instead of multiplying x+3 on both sides, I would instead subtract 2 on both sides. If you do this, it would be easier to write this equation in standard form and find the intervals.

In summary, to solve the inequality (x - 2)/(x + 3) ≥ 2, we can multiply both sides of the inequality by x + 3 only when x > -3 to preserve the direction of the inequality.

To solve the inequality (x - 2)/(x + 3) ≥ 2, we need to consider the impact of multiplying both sides of the inequality by x + 3.

When multiplying both sides of an inequality by a positive number, the direction of the inequality remains the same. However, if we multiply both sides by a negative number, the direction of the inequality is reversed.

In this case, the expression x + 3 is in the denominator of the left side of the inequality. If we multiply both sides of the inequality by x + 3, we need to consider two scenarios:

If x + 3 is positive: In this case, we can multiply both sides of the inequality by x + 3 without changing the direction of the inequality.

If x + 3 is negative: Multiplying both sides of the inequality by x + 3 would require flipping the direction of the inequality.

Therefore, we need to ensure that x + 3 is positive before multiplying both sides by x + 3 to preserve the direction of the inequality.

To determine when x + 3 is positive, we set the denominator equal to zero and solve for x:

x + 3 = 0

x = -3

So, if x > -3, then x + 3 is positive.

In summary, to solve the inequality (x - 2)/(x + 3) ≥ 2, we can multiply both sides of the inequality by x + 3 only when x > -3 to preserve the direction of the inequality.

Answer:

[tex]\Huge\boxed{x=71.9}[/tex]

Step-by-step explanation:

Hello There!

Once again we are going to use trigonometry to solve for x

Here are the Trigonometric Ratios

sin = opposite divided by hypotenuse

cos = adjacent divided by hypotenuse

tan = opposite divided by adjacent

we need to find x and we are given its opposite side length (58) and the adjacent side length (19)

this corresponds with tangent so once again we will be using tangent to solve for x

Looking at tangent we see that its equal to opposite divided by adjacent so we create an equation

[tex]tan(x)=\frac{58}{19}\\\frac{58}{19} =3.052631579[/tex]

now we have

[tex]tan(x)=3.052631579[/tex]

Once again we need to get rid of the tan

to do so we take the inverse of tan ( tan^-1) and apply it to each side

[tex]arcsin^-^1(tan(x))=x\\arcsin^-^1(3.052631579)=71.86191784[/tex]

finally we round to the nearest tenth

we're left with x = 71.9

(7x - 3) -(5-3x)​

= (7x - 3) - 5 + 3x      Made them without ​parentheses. For -(5-3x), because there are - in front them, which means to multiply -1, so it become -5+3x.
