Evaluate the function.
f(x) = -x2 - 4x - 19
Find f(-9)
Help plsss
Given the quadratic function below:
[tex] \large{f(x)= - {x}^{2} - 4x - 19}[/tex]
To find f(-9), simply substitute x = -9 in the function.
[tex] \large{f( - 9) = - {( - 9)}^{2} - 4( - 9) - 19} \\ \large{f( - 9) = - 81 + 36 - 19} \\ \large{f( - 9) = - 100 + 36 \longrightarrow \large \boxed { \purple{f( - 9) = - 64}}}[/tex]
Answer
f(-9) = -64Let me know if you have any doubts regarding the function.

1. After you retire in 17 years your goal is to have $100,000 in your investment account that earns 8% compounded annually. How much money would you need to deposit now to reach this goal
9514 1404 393
Answer:
$27,026.90
Step-by-step explanation:
The future value formula can be solved to find the present value required.
FV = P(1 +r)^t . . . future value of P compounded at annual rate r for t years
$100,000 = P(1 +0.08)^17
P = $100,000/3.70002 . . . . divide by the coefficient of P
P = $27,026.90
You would need to deposit #27,026.90 now to reach this goal.

work out the angle x please help.
Answer:
x is 13°.take the triangle to find the measure of x.180° -(85°+82°)=x
180°-167°=13°
For the given triangle the measure of the angle x is = 3 degrees.
Labeling the given figure,
since angle C and angle B are alternate angles
Therefore,
For the triangle ABE
The interior angle for A = x
The interior angle for B = 180 -98
= 92 degree
Since we know that,
The sum of the two interior angles of a triangle is equal to the exterior angle of the opposite side.
Therefore,
⇒ x + 92 = 180 - 85
⇒ x = 3 degrees.
Hence,
The measure of the angle x is = 3 degrees.

A bag contains 2 white balls, 3 red balls and a black ball. if a ball is selected at random, what is the probability that it is (a). not white
(b). red
(c). black
Answer:
a) 2/3
b) 1/2
c) 1/6
Step-by-step explanation:
2 white balls + 3 red balls + 1 black ball = 6 balls all together so then you do the number of balls over 6
Answer:
P( not white ) =2/3
P ( red)= 1/2
P( black) = 1/6
Step-by-step explanation:
2 white balls, 3 red balls and a black ball. = 6 balls
P( not white ) = number of balls not white / total = 4/6 =2/3
P ( red) = number of balls that are red/ total = 3/6 = 1/2
P( black) = number of balls that are black/ total = 1/6

Hannah leans a 16-foot ladder against a wall so that it forms an angle of 61° with the
ground. What's the horizontal distance between the base of the ladder and the wall?
Round your answer to the nearest tenth of a foot if necessary.
Answer:
7.8 feet
Step-by-step explanation:
We can determine the Horizontal distance using trigonometry ;
Using the relation :
Cosθ = adjacent / hypotenus
Cos 61 = x / 16
x = cos 61 * 16
x = 0.4848096 * 16
x = 7.756
x = 7. 8 feet

Answer:
60 gallons
Step-by-step explanation:
The area of the trapezoid-shaped wall is given by ...
A = 1/2(b1 +b2)h
where b1 and b2 are the lengths of the parallel sides, and h is the perpendicular distance between them.
The area of the wall is ...
A = (1/2)(5 ft + 15 ft)(6 ft) = 60 ft²
If it takes 1 gallon to cover 1 square foot, then it will take 60 gallons to cover 60 square feet.
Isha needs 60 gallons of paint.
Answer:
Isha needs 60 gallons of paints to the wall.
Step-by-step explanation:
The area of trapezoid shaped like wall is given by :-
Area of trapezoid = 1/2 × ( Base ¹ + Base ² ) × H
Where,
B ¹ and B ² are the length of bases and H is the perpendicular distance between them.
Area of wall = 1/2 × ( Base¹ + Base²) × Height
Where, according to question we have
Base ¹ = 5 t Base ² = 15 ftAnd , Height = 6 ftsubstitute the values
Area = 1/2 × ( 5 ft + 15 ft ) × 6 ft
add the values of Base¹ and Base ²
Area = 1/2 × 20 ft × 6 ft
multiply
Area = 1 / 2 × 120 ft ²
divide
Area = 120 ft ² / 2 = 60 ft ²
It takes 1 gallon to cover 1 ft ². ... ( given)
So, For covering 60 ft ² it takes 60 gallons .
check
( 1 × 60 ) gallon = 60 ft ²
60 gallon = 60 ft²

In a normal distribution, 95% of the data fall within how many standard deviations of the mean? O A. Three standard deviations B. It cannot be determined from the given information. O C. Two standard deviations O D. One standard deviation SUBM
Answer:
Two standard deviations
Step-by-step explanation:
The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;
one standard deviation lie within 68% of the mean
Two standard deviations lie within 95%
Three standard deviations lie within 99.7%
Hence, for the question given, 95% fall within 2 standard deviations of the mean

9514 1404 393
Answer:
A
Step-by-step explanation:
It is usually sufficient to look at one section of the graph to answer a question like this. Often the best choice is the section that has a solid dot at the end of the curve. Here, that is the right section.
The left end of the right section is at x=-2, so that part of the function is defined for x ≥ -2. The line to the right has a positive slope, so the coefficient of x will be positive.
Only one answer choice has a positive x-coefficient for x ≥ -2.
[tex]\textbf{A. }\begin{cases}-x-2&\text{if }x<-2\\x+4&\text{if }x\ge-2\end{cases}[/tex]
Answer:
Step-by-step explanation:
This graph is made up of two different, separate line segments. In other words, it comes in two pieces which can be described as a pair of linear functions.
We call this a "piecewise linear" function. Choice A is the best one.
Find the following list of data calculate a demean be the maid in and see the mouth or mothers of the numbers from
the picture
Given:
A fair die is rolled.
It pays off $10 for 6, $7 for a 5, $4 for a 4 and no payoff otherwise.
To find:
The expected winning for this game.
Solution:
If a die is rolled then the possible outcomes are 1, 2, 3, 4, 5, 6.
The probability of getting a 6 is:
[tex]P(6)=\dfrac{1}{6}[/tex]
The probability of getting a 5 is:
[tex]P(5)=\dfrac{1}{6}[/tex]
The probability of getting a 4 is:
[tex]P(4)=\dfrac{1}{6}[/tex]
The probability of getting other numbers (1,2,3) is:
[tex]P(\text{Otherwise})=\dfrac{3}{6}[/tex]
[tex]P(\text{Otherwise})=\dfrac{1}{2}[/tex]
Now, find the sum of product of payoff and their corresponding probabilities to find the expected winning for this game.
[tex]E(x)=10\times P(6)+7\times P(5)+4\times P(4)+0\times P(\text{Otherwise})[/tex]
[tex]E(x)=10\times \dfrac{1}{6}+7\times \dfrac{1}{6}+4\times \dfrac{1}{6}+0\times \dfrac{1}{2}[/tex]
[tex]E(x)=\dfrac{10}{6}+\dfrac{7}{6}+\dfrac{4}{6}+0[/tex]
On further simplification, we get
[tex]E(x)=\dfrac{10+7+4}{6}[/tex]
[tex]E(x)=\dfrac{21}{6}[/tex]
[tex]E(x)=3.5[/tex]
Hence, the expected winnings for this game are $3.50.
