Answer:
D. 140
Step-by-step explanation:
In the equation, [tex]ax^2+bx+c=0,[/tex] the discriminant can be found with [tex]b^2-4ac[/tex].
In this equation,
the discriminant would be: [tex](-10)^2-4(2)(-5)=100+40=140[/tex]
Answer:
D. 140
Step-by-step explanation:
D = b² - 4ac
So, let's identify our values.
a = 2
b = -10
c = -5
Now, we can plug in our values.
D = -10² - 4(2)(-5)
D = 100 + 40
D = 140
Find the surface area of the composite solid 6 ft 4 ft 5 ft 5 ft
The surface area of the composite solid is 165 [tex]feet^2[/tex].
We possess
4 triangles, each measuring 6 feet in height and 5 feet in base
4 rectangles, each measuring 5 feet long and 4 feet wide
1 square has side a = 5 feet.
The formula for a triangle's area is:
[tex]A_T=\frac{1}{2} bh[/tex]
Substitute:
[tex]A_T=\frac{1}{2} 5*6\\A_T=\frac{1}{2} 30\\A_T=15 ft^2[/tex]
Formula for calculating a rectangle's area:
[tex]A_R=lw[/tex]
Substitute:
[tex]A_R=5*4\\A_R=20 ft^2[/tex]
The formula for a square's area is as follows:
[tex]A_s=a^2[/tex]
Substitute:
[tex]A=s=5^2\\A_s=25 ft^2[/tex]
The composite solid's surface area is:
[tex]SA=4A_T+4A_R+A_s[/tex]
Substitute:
[tex]SA=4*15+4*20+25\\SA= 60+80+25\\SA=165 ft^2[/tex]
The composite solid has a surface area of 165 [tex]feet^2[/tex].

The number of cases of a new disease can be modeled by the quadratic regression equation y = -2x^2 + 40x + 8. What is the best prediction for the number of cases in year 15
Answer:
158 cases
Step-by-step explanation:
Given tbe quadratic regression model :
y = -2x^2 + 40x + 8
y = number of cases of a new disease
x = number of years
The predicted number of cases of a new disease in 15 years can be calculated thus ;
Put x = 15 in the equation ;
y = -2(15)^2 + 40(15) + 8
y = - 2 * 225 + 600 + 8
y = - 450 + 600 + 8
y = 158
158 cases

Answer:
if I'm right, you are trying to find the area of the parallelogram. if you are trying to find the area, then based on the information provided, you need to add the purple side (9.2 cm) with the grey side (2 cm) which gives you 11.2 cm. then you would multiply this answer by the blue line (7 cm) giving you 78.4 cm. finally, you divide this by 2 giving you 39.2 cm. I'm not sure if this was what you were looking for, but I hope this helps either way.
Step-by-step explanation:
(9.2 + 2) x 7/2
11.2 x 7/2
78.4/2 = 39.2

Fuel for an outboard motor has a gas to oil ratio of 50:1. How much oil is needed for 25.5L of gas?
Answer:
The oil needed is 0.51.
Step-by-step explanation:
Since you know that the gas to oil ratio is 50:1 and you have to find the oil needed for 25.5L of gas, you can write the numbers in the ratio as a fraction and let's consider that x is the amount of oil needed:
[tex]\frac{50}{1} = \frac{25.5}{x}[/tex]
Now, you have to solve this using cross multiplication:
50*x=25.5*1
50x=25.5
Finally, your have to isolate the variable x:
x=25.5/50
x=0.51
According to this, the answer is that the oil needed is 0.51.
Line / is shown on the graph below. If another line is drawn, perpendicular to line I, what must be its slope?
Answer:
Undefined
Step-by-step explanation:
The slope on the graph is horizontal so there's no slope and the answer is just y = 3
For a line to be perpendicular to a horizontal line, it is going to be a vertical line.
All vertical lines have an undefined slope.

what is the area of the white box
Answer:
12 m²Step-by-step explanation:
The white box is a rectangle with width of:
a = 2 m
and length of:
b = 7 m - 1 m = 6 m
So its area is A = 2 m × 6 m = 12 m²
{The shaded blue area is: (5 m + 1 m)(8 m) - 12 m² = 48 m² - 12 m² = 36 m²}

Levi and his family belong to a family share plan for their cell phones. The pan includes unlimited minutes, text, and
Internet access for a monthly charge of $250.00 plus $10 for each line. Their plan may include as few as 2 lines and as
many as 12 lines. Complete the table to determine the cost for each plan member. Write a function that can be used
to determine the cost per month, y, for each plan member, X.
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of calculations of bills.
The bill calculation goes as equation,
y = $250 + n*($10)
here, n = number of lines,
1.) For n = 2 , Y = cost = 250 + 20 = $270
2.) for n = 4 , Y = $290
3.) for n = 6 , Y = $310
4.) for n = x, Y = $250 + x*($10)
for lastly 12 members we get as,
Y = 250 + (12)*(10) = 250+120 = $370
