Step-by-step explanation:
200+50m >1250
This means that for every month her grandmother gives 50 for an unknown amount of months along with the first 200 dollars.
The greater than 1250 shows that until she is greater than 1250 she'll keep getting money
14. What is the length of a diagonal of rectangle EFGH? Show your work
Answer:
The length of the diagonal of the rectangle is of [tex]\sqrt{58}[/tex] units.
Step-by-step explanation:
Pythagorean theorem:
The square of the hypothenuse h is equal to the sum of the squares of sides a and b, that is:
[tex]h^2 = a^2 + b^2[/tex]
Diagonal of a rectangle:
The diagonal is the hypothenuse, while the sides are a and b.
In this question:
The height has coordinates are y = 9 and y = 12, so the height is [tex]a = 12 - 9 = 3[/tex]
The length has coordinates at [tex]x = -6, x = -13[/tex], so the length is [tex]b = -6 - (-13) = 7[/tex]
Diagonal:
[tex]d^2 = a^2 + b^2[/tex]
[tex]d^2 = 3^2 + 7^2[/tex]
[tex]d^2 = 9 + 49[/tex]
[tex]d^2 = 58[/tex]
[tex]d = \sqrt{58}[/tex]
The length of the diagonal of the rectangle is of [tex]\sqrt{58}[/tex] units.

Answer:
[tex] \displaystyle \angle1 = {73}^{ \circ} [/tex]
Step-by-step explanation:
remember that,
the sum of the interior angles of a triangle is 180°
Thus our equation is
[tex] \displaystyle \angle1 + {72}^{ \circ} + {35}^{ \circ} = {180}^{ \circ} [/tex]
simplify addition:
[tex] \displaystyle \angle1 + {107}^{ \circ} = {180}^{ \circ} [/tex]
cancel 107° from both sides:
[tex] \displaystyle \angle1 = {73}^{ \circ} [/tex]
Step-by-step explanation:
Answer:
Solution given:
<1+72+35°=180°[ interior angle of a triangle is 180]
<1=180-107
<1=73 °

Use the graphs below to help you answer the question.
Which is the best approximation to a solution of the equation ln x = x - 2
- 2
1
2
3
Answer:
Here we can not see the graph, so I will upload a new graph for this case.
To solve the equation:
Ln(x) = x - 2
We can first graph the equations:
y = Ln(x)
y = x - 2
And find the point where these graphs intersect.
In the graph we can see two intersects.
One (the first one) is near the point ( 0.15, -1.85)
And the other intersection is near the point (3.14, 1.14)
Then two possible values of x that are solutions of:
ln(x) = x - 2
are:
x = 0.15
x = 3.14
The value of a car is decreasing by 12% per year. If the car is worth $11,000 today, what will it be worth in two years?
Answer:
$8518.40
Step-by-step explanation:
FV = PV(1+r)^n
FV = future value
PV = present value
r = rate
n = # of years
Value in 2 yrs = 11,000 x (1 - 0.12)^2 = 8518.4

Answer:
8.3
Step-by-step explanation:
It has been awhile since I have done this so I may be a bit rusty.

Un aserradero adquiere maquinaria y equipo para el corte de madera, que va perdiendo valor conforme transcurren los años, hasta que su valor contable es cero, como indica la gráfica de la función D(x)=(-x^3+2x^2+20x+20)/(x^2+4x+4) que modela esta depreciación en el eje y cada unidad son 20 000 pesos y en el eje x cada unidad es de 3 años.
a) ¿Cuál es el valor inicial del equipo y herramienta? ¿cuánto se ha depreciado al cabo de 12 años?
b) ¿existe un modelo lineal que aproxime los mismos valores que la función D(x)?
c) ¿En cuánto difieren los valores de ambas funciones al cabo de 9 años?

What is the value of x in the equation −x = 3 − 4x + 6?
−9
−3
3
9
Answer:
The answer is 3
Answer:
x = 3
Step-by-step explanation:
-x = 3 - 4x +6
make the -4x positive and then add it to the -x
-x = 3 +6
+4x
3x = 3 +6
then add the 3 +6 together
3x = 3 + 6
9
3x = 9
we want to get X alone so we are going to divide 3 by both sides
3x/3 = 9/3
1x = 3
and if you did not know we usually don't show the "1" if it is in front of a exponent (you just have to remember that there is a one there)
now you have your answer
x = 3

In ΔPQR, the measure of ∠R=90°, QP = 85, RQ = 13, and PR = 84. What ratio represents the cosecant of ∠P?
Given:
In ΔPQR, the measure of ∠R=90°, QP = 85, RQ = 13, and PR = 84.
To find:
The cosecant of ∠P.
Solution:
In a right angle triangle,
[tex]\text{cosec}\theta =\dfrac{Hypotenuse}{Perpendicular}[/tex]
It is also written as:
[tex]\text{cosec}\theta =\dfrac{Hypotenuse}{Opposite}[/tex]
In triangle PQR, QP is the hypotenuse because ∠R=90°.
[tex]\text{cosec}P =\dfrac{QP}{RQ}[/tex]
[tex]\text{cosec}P =\dfrac{85}{13}[/tex]
Therefore, the required trigonometric ratio is [tex]\text{cosec}P =\dfrac{85}{13}[/tex].

PLEASE HELPPP!!!!!!!!
Answer:
C. y=-3x+5
Step-by-step explanation:
Looking at the line, you see that it goes down 3 places for every unit step to the right, so the slope is -3 and we expect a -3x in the answer.
Looking at the intersection with the y-axis, it is at (0,5), so we expect -3x + 5.
We have to be at the left of this line, i.e. y < -3x + 5.
That's answer B.

Step-by-step explanation:
If event A is certain to occur, what is P(A)?
Answer:
Unless I'm misunderstanding it should be 100% or 1/1 because something that is 100% likely to happen will always happen.
Step-by-step explanation:
If there is anything else that may change my understanding of this please send it otherwise I hope this helps.
The value of P(A) is 1 where A is the event that is certain to occur because the probability of any event is 1 which means that event is certain to occur.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that:
If event A is certain to occur.
As we know,
From the definition of probability, the ratio of the number of favorable outcomes to the total number of outcomes
The value of the probability lies between 0 to 1 or [0, 1]
If the probability of any event is 0 that means that event cannot happen.
If the probability of any event is 1 that means that event is certain to occur.
Event A is certain to occure.
P(A) = 1
Thus, the value of P(A) is 1 where A is the event that is certain to occur because the probability of any event is 1 which means that event is certain to occur.

Answer:
False
Step-by-step explanation:
The terms of a geometric series would have a common ratio. The terms of this series do not. (The differences increase by 1 each time, so it is a quadratic series.)
False, the series is not geometric.
