Answer:
414cm^2
Step-by-step explanation:
Given data
Base a= 9cm
Hence the expression for the surface area is
SA=2a^2+4ah
A=2*9^2+4*9*7
A=162+252
A=414cm^2
Hence the surface area is 414cm^2

Answer 3/8
Answer:
[tex]P(sister) = \frac{8}{30} \\ [/tex]
Step-by-step explanation:
[tex]P(sister) = \frac{8}{30} \\ P(brother) = \frac{13}{30} \\ P(SnB) = \frac{3}{30} \\ [/tex]
Which factored polynomial is shown in the graph?
A) y = (x + 2)(x + 1)(x + 4)
B) y = (x + 2)(x − 1)(x + 4)
C) y = (x + 2)(x − 1)(x − 4)
D) y = (x − 2)(x − 1)(x + 4)
Answer:
B
Step-by-step explanation:
First, we can determine the zeros of the function.
We can see that the graph passes through the x-axis at the points: x = -4, -2, and 1.
Therefore, we have three factors:
[tex](x-(-4)),\, (x-(-2))\text{ and } (x-(1))[/tex]
Thus, our function will be:
[tex]y=(x+4)(x+2)(x-1)[/tex]
Our answer is B.

Jacob used a simulation to predict the chance that a canal will flood in 1 of the next 6 years. A number 1 indicates a year in which the canal will flood. Numbers 2, 3, or 4 indicate a year in which the canal will not flood. The results of the simulation are shown. What is the experimental probability that a canal will flood in at least 1 of the next 6 years?
here is the table and the question
Answer:
is there like answer choices or do you just fill it in? if so then i think it would be unlikely.
Step-by-step explanation:
there’s only 7 ones which is the number that shows it will flood so 7/36 is unlikely, it has to be more than half to be likely

A car speed increases from 40 km/hr to km/hr in 5 sec. Calcuate the acceleration of car:
Answer:
14400km/h
Step-by-step explanation:
Given that
The speed of the car increased from 40 km/hr to 60 km/hr
And, the time taken is 5 seconds
we need to find out the acceleration of the car
So,
Here
u = initial velocity =40km/h
v = final velocity =60km/h
t = time = 5s =5 ÷ 3600h
a = acceleration
Now as we know that
a = (v - u) ÷ t
= (60 - 40) ÷ (5 ÷ 3600)
= (20 × 3600) ÷ 5
= 14400km/h

How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.

Answer:
J p = 8t +12
Step-by-step explanation:
You can see that the p-values have differences of 8, while the t values have differences of 1. That means the "rate of change" is 8/1 = 8. This will be the coefficient of t in the equation you're looking for.
Only one answer choice has 8t as part of the equation:
p = 8t +12
______
Additional comment
If you decide to try the values of t in the offered choices, it often works to start with the second value of t. The answer choices are sometimes tailored to match for the first value in the table. Usually the second value of t will quickly identify the correct one.
For t=2, ...
F: p = 20·2 = 40 ≠ 28
G: p = 11·2 = 22 ≠ 28
H: p = 20·2 +12 = 52 ≠ 28
J: p = 8·2 +12 = 28 . . . . the correct choice

If two points known on the line AB in the coordinate plane is (7,15) and (18,42), calculate the following..
A) the slope of the line AB
B) The length of the line AB
Answer:
Slope = 27/11
AB = 29.15 u
Step-by-step explanation:
Given :-
Two points are given to us .The points are A(7,15) and B(18,42)To Find :-
The slope of the line .The length of line AB .We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,
[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]
Plug in the respective values ,[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]
Hence the slope of the line is 27/11 .
[tex]\rule{200}2[/tex]
Finding the length of AB :-
We can find the distance between them by using the Distance Formula .[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]
Hence the length of AB is 29.15 units .

Which expression is equivalent to (6x3+3x2+8)+(2x2−9x+10)?
Answer:
Which expression is equivalent to (6x3+3x2+8)+(2x2−9x+10)?
Step-by-step explanation:
6x3+3x2+8)+(2x2−9x+10)?
The equivalent expression is 6x^3+5x^2-9x+18.
What is an algebraic expression?An expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Algebraic expressions include at least one variable and at least one operation.
For the given situation,
The expression is [tex](6x^3+3x^2+8)+(2x^2-9x+10)[/tex]
⇒ [tex]6x^{3}+3x^{2} +8 +2x^{2} -9x+10[/tex]
Rearrange the expression in decreasing order of polynomial,
⇒ [tex]6x^{3}+3x^{2}+2x^{2} -9x+8+10[/tex]
Now add the like terms,
⇒ [tex]6x^{3} +5x^{2} -9x+18[/tex]
Hence we can conclude that the equivalent expression is [tex]6x^{3} +5x^{2} -9x+18[/tex].

What’s the value of x
Answer:

Step-by-step explanation:
According to the inscribed Angle Theorem, the size of an inscribed angle = ½(measure of the intercepted arc)
m<L = (7x + 9)° is an inscribed angle
m(KM) = 46° is its intercepted arc
Therefore:
7x + 9 = ½(46)
Multiply both sides by 2
2(7x + 9) = 46
14x + 18 = 46
14x + 18 - 18 = 46 - 18
14x = 28
14x/14 = 28/14
x = 2
