Evaluate the function for an input value of 3. f(x)= −4x 2 −3x−5
Answer:
- 50
Step-by-step explanation:
x = 3
f ( x ) = - 4x^2 - 3x - 5
f ( 3 )
= - 4 ( 3 )^2 - 3 ( 3 ) - 5
= - 4 ( 9 ) - 3 ( 3 ) - 5
= - 36 - 9 - 5
= - 50
Choose the correct simplification of the expression a^9 multiplied by b^10/a^2 multiplied by b^7
A^11b^17
1/a^11b^17
1/a^7b^3
A^7b^3
Answer:
a^7 b^3
Step-by-step explanation:
The question can be interpreted as
[(a^9)( b ^10)] / [(a^2 )×( b ^7)]
Then we can bring the denominator up, which means the power on the denominator will become (-ve) once it comes to the numerator side. Then we have
a^(9-2) × b^(10-7)
We can simplify by performing substraction on the power
= a^7 b^3

A rectangle has a perimeter of 30 yards. If one side is 5 yards long, how long is the other side?
A. 15 yards
B. 25 yards
C. 10 yards
D. 30 yards
Answer:
C. 10
Step-by-step explanation:
5+5=10
10+10=20
10+20=30
Answer:
The other is 10 yards long
Step-by-step explanation:
For a given rectangle
Perimeter (P) = 30 yards
and one of rectangle is 5 yards
Now,
Perimeter of rectangle
P = 2l + 2b
30 = 2(5) + 2b
30 = 10 + 2b
30 - 10 = 2b
20 = 2b
b = 20 ÷ 2
b = 10 yards
Thus, The other is 10 yards long

The ratio of boys to girls in class is 4 : 5
What fraction of the class are boys
Answer:
The ratio of boys to girls is 4:5. So let 4x be the number of boys and 5x be the number of girls. Then 4x+5x = 9x is the total number of students. Then the fraction of boys in the class is 4x/9x = 4/9.

Step-by-step explanation:
Properties of a triangle:
Triangles always have 3 sidesThe sum of the interior angles of a triangle must be equal to 180°.To solve:
Since the angles inside of a triangle must always be equal to 180, use the following formula to solve:a + b + c = 180(The variables can be assigned to any value in this situation)Since two angles are already given, replace 2 variables:a + 85 + 30 = 180Solve the equation by subtracting on both sides:a = 65The value of a is the measure of the missing angle. The problem is solved.Answer:
the missing angle is 65
Step-by-step explanation:
a whole triangle is 180
subtract the given angles from 180
180
- 85
----------
95
subtract the remaining angle

Evaluate the function.
f(x)= - x^2 - 10x
find f(-5)
Answer:
f(- 5) = 25
Step-by-step explanation:
To evaluate f(- 5) , substitute x = - 5 into f(x) , that is
f(- 5) = - (- 5)² - 10(- 5) = - 25 + 50 = 25

If a toy truck is created in a 2:9 scale, and the wheel of the toy is 14cm wide, how wide is the actual wheel?
Answer:63 cm
Step-by-step explanation:
Given
The scale of creation is 2:9
The width of the toy wheel is 14 cm
Suppose x is the actual width of the truck
[tex]\therefore \dfrac{2}{9}=\dfrac{14}{x}\\\\\Rightarrow x=\dfrac{9}{2}\times 14=63\ cm[/tex]
Thus, the width of actual truck is 63 cm
Nkechi wants to use a one-sample z interval to estimate what proportion of candies in a bag are red. She takes a random sample of 24 of the 80 total candies and finds that 18 of the candies in the sample are red. Which conditions for constructing this confidence interval did Nkechi's sample meet? Choose all answers that apply
Answer: The data is a random sample from the population of interest.
Step-by-step explanation: The condition is met since she randomly selected the sample from the population of interest.
The data is a random sample from the population of interests.(Option A), and individual observations can be considered independent.(Option C)
What are the conditions for valid inference about one proportion?Random sample: The sample should be taken randomly.Normal distribution of proportion: The sampling distribution of the proportion we're taking about should be normally distributed.Independent observations: Each of the observations must be independent.The missing options are:
A. The data is a random sample from the population of interests.
B The observed counts of successes and failures are both sufficiently large.
C. Individual observations can be considered independent.
For this case, we're given that the sample was random.
Sample size is 24,which is not sufficiently large (usually we take > 30 as sufficiently large size).
Also, each candle was independent for being red colored.
Thus, the data is a random sample from the population of interests.(Option A), and individual observations can be considered independent.(Option C)

Answer:
The y-int represents the base price of $200 for airfare from NYC
The slope represents a cost of 30 cents per mile traveled
If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y=50+0.30x
If the cost per mile changed to 50 cents, the new equation would be y=200+0.50x
