Step-by-step explanation:
Explanation:
Because
(2,6) is in the function, we can plug
6 as y
and
2 as x.
From that we get
6=a(2−1)2+k
6=a+k
Same for the next point:
12=a(3−1)2+k
12=22a+k
12=4a+k
Now we have this system of equations to solve:
a+k=6
4a+k=12
Solving it leads to the conclusion that
a=2,k=4 .

Which function is best represented by the graph?
Answer:
J
Step-by-step explanation:
First look at the y-intercept. When y=0, you get 8 on the graph, so in the equation it has to give you 8 as well.
This narrows it down to F G J
Next, the slope of the graph is negative because its tilting downwards.
This narrows it down to G J
Finally, on the graph when y=0, you get 6, so the equation has to meet this too
With your choices narrowed down to G and J, calculate the x-intercepts.
0= -4/3x+8
-8= -4/3x
-8(-3/4)=x
x=6
Answer:
The answer is J
Step-by-step explanation:
the y-intercept is 8 and to find the slope you count rise over run, well the graph is too small to tell what points are actually on the lines, but it's given that (0,8) and (6,0) are points. making the rise/run= to 8/6 and then simplify to 4/3. and you can tell that the slope is negative because it's going downward from left to right.

Okay so ur at a party and they have donuts, 5/25 of the donuts are eaten. What percent of them are left?
If it's not too much trouble could you explain how to solve it? If not I guess I'll live:(
Answer:
80%
Step-by-step explanation:
100%= 25/25. 1 donut = 5%. So you have 20 donuts left x 5.
Answer:
80% are left.
Step-by-step explanation:
So 100 donuts would be 100%. To get to 100 you need to multiply 25x4. Then you also need to multiply 5x4=20. Since it is the 5 that are eaten, you subtract 20 from 100 and get 80, so you are left with 80% of the donuts.
Which statements accurately compare the functions in the graph? Select two options.
Neither function has a maximum value.
The functions share a y-intercept of –1.

Both functions have a range of all real numbers.
Both functions have a domain of all real numbers.
Answer:
The functions share a y-intercept of –1.
Both functions have a range of all real numbers.
Step-by-step explanation:
They are marked on the y axis with the point, (0,-1)
Secondly, becuase both go along the range, or y axis line, I believe it is is both functions have an all real numbers range.
Hope this helps, let me know if I'm wrong.
The functions share a Y-intercept of –1.
Both functions have a range of all real numbers.
What is real number?
Real number is a set of numbers that has integers, rational numbers, and natural numbers.
Here, we can see, both the functions meet on the Y-axis at a point (0,-1).
Therefore, Both the functions share a Y-intercept of –1.
Again, both the functions have a certain value of Y for a given value f X. Hence, both functions have a range of all real numbers.

Step-by-step explanation:
A peach pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice of pie that contained exactly 5 peaches, what wqs the angle measure of the slice to the nearest tenth of a degree?
Answer:
138.5°
Step-by-step explanation:
A peach pie is in the form of a circle. The sum of angles in a pie is equal to 360°.
Since there are 13 peaches evenly distributed, therefore each peach occupies 360/13 degrees.
Joe ate one slice of pie that contained exactly 5 peaches, hence:
Angle measure of slice = (number of peaches in the slice / total number of peaches) * 360°
Angle measure of slice = (5 / 13) * 360°
Angle measure of slice = 138.5°

If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas, how much did he spend? Amount spent can be represented by the exper
Answer:
$5.77
Step-by-step explanation:
Given expression:
1.8s + 0.65b
where,
s = the number of pounds of strawberries
b = the number of pounds bananas
If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas
s = 2.7 pounds
b = 1.4 pounds
how much did he spend?
1.8s + 0.65b
= 1.8(2.7) + 0.65(1.4)
= 4.86 + 0.91
= $5.77
He spent $5.77 on both items

Find the missing side length of the right triangle below
The length of base of the triangle is given by BC = 7 feet
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle BC = a
Let the hypotenuse of the triangle be c = 25 feet
Let the height of the triangle be b = 24 feet
And , For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
So , the base BC = √ ( 25 )² - ( 24 )²
The base of the triangle BC = √ ( 625 - 576 )
The base of the triangle BC = √ ( 49 )
The base of the triangle BC = 7 feet
Hence , the length of base of triangle is 7 feet
