Answer:
Jacob has a part-time job at an ice skating rink selling hot cocoa. He decided to plot the number of hot cocoas he sold relative to the day's high temperature and then draw the line of best fit. Based on the line of best fit, what would you predict the day’s high temperature to be if Jacob sold 89 hot cocoas?
Step-by-step explanation:
Parker would sell 93 hot cocoas.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
From the Curve we can write
slope = (101 - 105) / (5- 0)
slope = -4/5
so, the equation to represent the situation is
= -4/5t + 105
= -0.8t + 105
Now, if t= 15 then
s= -12 + 105
s = 93

The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel side is 20m. Find the other parallel side
Answer: 44 m
Step-by-step explanation:
Given
The area of the trapezium is [tex]A=480\ m^2[/tex]
Distance between parallel sides [tex]h=15\ m[/tex]
One of the parallel sides is [tex]20\ m[/tex]
Suppose the other parallel side is [tex]x[/tex]
The area of the trapezium is
[tex]A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h[/tex]
Put values
[tex]\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m[/tex]

please make me a happy with brainleist answer
The value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory option (A) is correct.
What is LIFO?Last in, first-out (LIFO) is an inventory valuation approach based on the principle that the first asset sold is the most recent asset received.
We have data shown in the table:
Total number of T-shirts = 200+300+400+300 = 1200
As there are only 400 T-shirts left it means,
So (1200-400)800 T-shirts sold out according to LIFO last month T-shirt sold out.
200 T-shirts left in the June stock
Out of 300, there are 200 T-shirts left in the month of July.
Cost for 200 T-shirts = 200×8 = $1600
Cost for 200 T-shirts = 200×10 = $2000
Total cost = 1600+2000
= $3600
Thus, the value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory.

Step-by-step explanation:
A batter hits a baseball 4 feet above the ground with an upward velocity of 59 feet per second. The function h(t) = -16t^2 + 49t + 4 gives the height h (in feet) of the baseball after t seconds. How long is the ball in the air if a player on the other team catches the ball 7 feet above the ground?
Answer:
3 seconds
Step-by-step explanation:
when h=7 ft
-16t²+49t+4=7
-16t²+49t-3=0
16t²-49t+3=0
16t^2-48t-t+3=0
16t(t-3)-1(t-3)=0
(t-3)(16t-1)=0
t=3,t=1/16
t=1/16 seconds is the time when it just started.

Answer:
y ≤ 66.28 -> -∞
Step-by-step explanation:
y = a (x-h)² + k ... (h,k): vertex
y = - 32x² + 90x + 3
= -32 (x² - (90/32)x + (90/64)²) + (3 + (32)*(90/64)²)
= -32 (x² - 2*(90/64)x + (90/64)²) + (3+63.28) ... 90/64=1.41
= -32 (x - 1.41)² + 66.28
h = 1.41
k = 66.28 .... extremum of y value
y ≤ 66.28 (y is real number)
