Which could be the function graphed below?
Answer:
Probably A, or 1
Step-by-step explanation:
You see, a square root function actually looks like a sideways parabola, just missing one side because of the domain of a square root. Now, the reason I can tell them apart is because our vertex is below the y-axis, and the only equation that has a negative y-intercept is the first one, or A.

The answer is B.
Step-by-step explanation:
You have to use Pythogorean Theorem, c² = a² + b² where c is the hypotenuse and a,b is the side lengths :
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
Let a = 40,
Let b = 9,
[tex] {c}^{2} = {40}^{2} + {9}^{2} [/tex]
[tex] {c}^{2} = 1600 + 81[/tex]
[tex] {c}^{2} = 1681[/tex]
[tex]c = \sqrt{1681} [/tex]
[tex]c = 41 \: units[/tex]
*Take note, hypotenuse will always be the longest length among the 3 lengths.
*Pythogorean Theorem can only applied in a right-angle triangle.
Abigail has $30.00 to buy groceries.she needs to buy some apples,some bananas, and 3 pounds of potatoes.Fuji apples are $1.79 a pound ,bananas are$0.36 each, and potatoes are 2.99 for a 3 lb bag. If a represents the number of pounds of apples Abigail buys b represents the number of bananas she buys,which expression represents the amount of change she receives after her purchases?
Answer:
An expression represents the amount of change she receives after her purchases is y=-1.79a-0.36b+27.01
Step-by-step explanation:
Let a represents the number of pounds of apples
Let b represents the number of bananas
Cost of 1 pound apple = $1.79
So, Cost of a pounds apples = 1.79 a
Cost of 1 banana = $0.36
Cost of b bananas = 0.36b
Cost of 3 lb bag of potato i.e. 3 pounds of potato = $2.99
So, Total cost = 1.79a+0.36b+2.99
Abigail has $30.00 to buy groceries
Let y be the change received by her
So, Change received by her:
y = 30-( 1.79a+0.36b+2.99)
y= 30-1.79a-0.36b-2.99
y=-1.79a-0.36b+27.01
Hence expression represents the amount of change she receives after her purchases is y=-1.79a-0.36b+27.01

Part A: What is the value of 2x if 4x + 6 = 2x – 12?
Part B: What is the value of x – 3 if 24 = 6x – 18?
Answer:
Step-by-step explanation:
A) 4x + 6 = 2x - 12
Subtract 6 from both sides
4x + 6 - 6 = 2x - 12 -6
4x = 2x - 18
Subtract 2x form both sides
4x - 2x = 2x - 18 - 2x
2x = -18
B) 24 = 6x - 18
6x - 18 = 24
6x - 6*3 = 24
6(x - 3) = 24
Divide both sides by 6
[tex]\frac{6(x - 3)}{6}=\frac{24}{6}\\\\[/tex]

Concrete is made by mixing cement, sand, and
gravel in the ratio 5:9:13. How much cement
is nceded to make 324 ft of concrete?
Answer:
60
Step-by-step explanation:
Sum the parts of the ratio, 5 + 9 + 13 = 27 parts
Divide the amount of concrete by 27 to find the value of one part of the ratio.
324 ÷ 27 = 12 ← value of 1 part of the ratio , thus
5 parts = 5 × 12 = 60 ← cement
9 parts = 9 × 12 = 108 ← sand
13 parts = 13 × 12 = 156 ← gravel
To make 324 ft of concrete, we would need 60 ft of cement.
We have,
Given the ratio of cement, sand, and gravel as 5:9:13, we can consider the total number of parts in the mixture as 5 + 9 + 13 = 27 parts.
Now,
27 parts = 324 ft
Divide both sides with 27.
1 part = 324/27 ft
1 part = 12 ft
Now,
1 part = 12 ft
Multiply 5 on both sides.
5 parts = 5 x 12 ft
5 parts = 60 ft
Therefore,
To make 324 ft of concrete, we would need 60 ft of cement.

Dr. Stein bought 30 notebooks, 60 pencils and 300 erasers for his class to make identical packages with some notebooks, some pencils and some erasers for his students. He used everything he bought, and every student got a package. What is the largest number of students Dr. Stein can have in his class?
The key word is "identical." If all students received identical packages, then Dr. Stein could have handed out 30 packages. He has a maximum of 30 notebooks to hand out, so if each package has one notebook, he can hand out 30 packages. Each of those 30 packages will also have 2 pencils and 10 erasers.
ANSWER: There are 30 packages maximum so he can have a maximum of 30 students.
