Tell whether the graph of the quadratic function
y − 4x2 = 4x + 5 opens upward or downward and whether the function has a maximum or a minimum.
The graph opens (select: downward, upward) and and the function has a
(select: maximum, minimum).
Answers
Answer: Graph attached.
Step-by-step explanation:
It is easier to figure it out if you can see it.
Also easier if you rewrite the equation in quadratic form:
y = 4x² + 4x + 5

HELP PLEASE LOOK AT THE IMAGE NO WRONG ANSWERS
Answers
Add all the answers up and you get 327
All the angles added up should equal to 360
360-327= 33
Answer:
D) 33 degrees
Step-by-step explanation:
All interior angles of a quadrilateral must equal 360 degrees.
We have 3/4 angles, so let's write an equation:
360=x+265+32+30
simplify
360=327+x
subtract 327 from both sides
33=x
So, D is the correct option.

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.
Answers
We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:
0.80D = 0.24L
We are also given that the mass of the lion is 105 kg more than the mass of the dog:
L = D + 105
We can use these two equations to find the values of D and L.
Substituting the value of L from the second equation into the first equation:
0.80D = 0.24(D + 105)
Now, let's solve for D:
0.80D = 0.24D + 0.24(105)
0.80D - 0.24D = 25.2
0.56D = 25.2
D = 25.2 / 0.56
D ≈ 45
Now that we have the value of D, we can find the value of L by substituting it back into the second equation:
L = 45 + 105
L = 150
Therefore, the total mass of the dog and the lion is:
D + L = 45 + 150 = 195 kg
So, the total mass of the dog and the lion is 195 kg.

Solve the inequality $-8r<-12$.
Please help i will put up 10 points
Answers
Answer:
Step-by-step explanation:
im assuming you solve for r.
-8r<-12
divided by -8 on both sides so you change signs
r>12/8
r> $ 3/2
Answer:
$r > 1.5$ or \(\frac{3}{2}\)$
Hope this helps!
Step-by-step explanation:
Hiding the dollar signs real quick:
-8r < -12
Divide both sides by -8: ( remember that when multiplying or dividing both sides by a negative number reverses the inequality )
-8 ÷ -8 × r < -12 ÷ -8 = r > 1.5 or \(\frac{3}{2}\)

6+8+10= 24 parts all together
Sarah has $50 and equals 10 parts. So, each part is worth $5. (50/10=5)
Thus, Ben receives 6 parts, with each part being $5. So, Ben gets $30. (6x5=30)
Answer:
Ben = 30
Step-by-step explanation:
Ben = 6 Jack = 8 Sarah = 10 10= 50 = 10(5)= Sarah if we (5) for Jack and Ben we an total to find 50+ 8(5) + 6(5) = 50 + 40 + 30= 120 total and Ben = 30

In Jason's class, 1/2 of the boys have brown eyes, 1/5 of the boys have blue eyes, and 3/10 of the boys have hazel eyes. How many more of the boys have brown eyes than hazel eyes?
Answers
Answer:
2
Step-by-step explanation:
ist you have to lind the lcd of each fraction. that would be 10.
1/2x5/5=5/10 of the boys have brown eyes
1/5x2/2=2/10 of the boys have blue eyes
3/10=3/10 of the boys have hazel eyes
The question is asking to see how many more boys have brown eyes than hazel eyes.
Subtract 3/10 from 5/10
and that gives you 2/10
The answer is 1/5.
We know that half of the boys in Jason's class has brown eyes, while three-tenths of the boys in his class have hazel eyes. Therefore, if we subtract the two values, you should get your answer.
\(\frac{1}{2} -\frac{3}{10} =\frac{2}{10}\)
1/5 is the simplified version of 2/10. Therefore, 1/5 is your answer.

The probability of sleet is given as 0.85. To express this probability as a fraction, we simply write the decimal as a fraction with a denominator of 1.
0.85 can be written as 85/100, which can be simplified by dividing both the numerator and denominator by 5 to obtain 17/20.
Therefore, the probability of sleet can be expressed as the fraction 17/20.
What is Probability?Probability is a measure of the likelihood of an event occurring and is expressed as a number between 0 and 1, inclusive. An event with a probability of 0 is impossible, while an event with a probability of 1 is certain.
Probabilities can be expressed as fractions, decimals, or percentages. To convert a decimal or a percentage to a fraction, we write the decimal or percentage as a fraction with a denominator of 1 and simplify the fraction if possible.
For example, if the probability of an event is given as 0.75, we can write this as 75/100. We can simplify this fraction by dividing both the numerator and denominator by 25 to obtain 3/4. Therefore, the probability of the event can be expressed as the fraction 3/4.
Similarly, if the probability of an event is given as 60%, we can write this as 60/100. We can simplify this fraction by dividing both the numerator and denominator by 20 to obtain 3/5. Therefore, the probability of the event can be expressed as the fraction 3/5.
Probabilities can be used to make predictions about the likelihood of future events, and they are an important tool in many fields, including statistics, science, and finance.
