Step-by-step explanation:
When (x - 2) = 0, x = 2.
=> F(2) = -4(2)² + 14(2) - 23 = -11.
By Remainder Theorem,
The remainder of F(x) divided by (x - 2) is -11.
What is the y-intercept of a line that has a slope of —3 and passes through point (0, -7)?
_7
-3
0
4
Answer:
-7
Step-by-step explanation:
well, y-intercept is value of y when x = 0.
from the problem, we already have the answer, it is -7
but more detailed way is
m = -3
[tex] \frac{y - ( - 7)}{x - 0} = - 3 \\ y - ( - 7) = - 3x \\ y = - 3x - 7 \\ [/tex]
y-intercept is value of y when x = 0
[tex]y = - 3(0) - 7 \\ y = - 7[/tex]

Answer:
Choice c. [tex]\sqrt{12}[/tex]
Step-by-step explanation:
Vectors
Suppose we have a vector v defined as
[tex]\vec v=a\mathvf{i}+b\mathvf{j}[/tex]
The magnitude of the vector is:
[tex]\mid\mid\vec v\mid\mid=\sqrt{a^2+b^2}[/tex]
On the other hand, the dot product of the vector by itself is:
[tex]\vec v\cdot\vec v=a*a+b*b=a^2+b^2[/tex]
Note the relation between these two operations is:
[tex]\mid\mid\vec v\mid\mid=\sqrt{\vec v\cdot\vec v}[/tex]
Since we are given:
[tex]\vec v\cdot\vec v=12[/tex], then:
[tex]\mid\mid\vec v\mid\mid=\sqrt{12}[/tex]
Choice c) [tex]\sqrt{12}[/tex]

Bo Karah can run a race in 4 hours 33 minutes if he runs at 7 m/s. How long will it take in hours and minutes if
he runs at 11 m/s? Give your answer to the nearest minute.
Answer:
7 hours and 9 minutes
Step-by-step explanation:
4 hours and 33 minutes is 273 minutes
7 m/s —> 273 minutes
11 m/s —> M
Criss cross to get M
11x273= 7M
3003=7M
M=429 minutes
==> 429 minutes is 7 hours and 9 minutes
If z varies inversely as x^2, and z = 9 when x = 2/3, find z when x = 5/4
Answer:
Step-by-step explanation:
z varies inversely
so z=a/x^2
9=a/(2/3)^2
9=a/(4/9)
9=9a/4
a=4
z=4/x^2
z=4/(5/4)^2
z=4/(25/16)
z=64/25
If z varies inversely as x², it is given by the equation z = 4/x². When x = 5/4, z = 2.56
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
z varies inversely as x². Let k represent the constant of proportionality, hence:
z = k/x²
z = 9 when x = 2/3, hence:
9 = k / (2/3)²
k = 4
z = 4/x²
When x = 5/4:
z = 4 / (5/4)²
z = 2.56
If z varies inversely as x², it is given by the equation z = 4/x². When x = 5/4, z = 2.56

(2 to the power -1 ÷ 5 to the power- 1)2 × -5/8 to the power -1
Answer:
-8
Step-by-step explanation
2 to the power of -1 = 0.5
5 to the power of -1 = 0.2
0.5/0.2 = 2.5
So,
(2.5)2 x -5/8 to the power of -1
-5/8 = -0.625
-0.625 to the power of -1 = -1.6
So,
(2.5)2 x -0.625
5 x -0.625
= -8
Answer:
-8
Step-by-step explanation:
(2^-1 ÷ 5^-1) = 5/2
(5/2) x 2 = 10/2 or 5
-5/8 ^-1 = - 8/5
5 x - 8/5 = -40/5 or -8

you roll a single die numbered from 1 to 6 twice. what is the probability of rolling a 6 the first time and an odd number second
Answer:
1/12
Step-by-step explanation:
Since the two rolls are independent, then the chance of getting a 6 in the first and an odd number in the second is obtained by multiplying the two probabilities.
1/6 is the probability of rolling 6, 1/2 is the probability of rolling an odd number
1/6 times 1/2 is 1/12
Becca made 960 cookies to sell. She wants to package the cookies in the the boxes of 16 . Her goal is to make $630 from selling her cookies . If each box of cookies is priced the same , how much should Becca charge for each box ?
Step-by-step explanation:
Total cookies = 960
Each box has 16 cookies
Her goal is $630
First, you want to find out how many boxes she made
960÷ 16 = 60
She made 60 boxes
Now you want to find the price for each box
630 ÷ 60 = 10.5
She should charge $10.50 for each box
I hope this helps!!!

Write the following inequality in slope-intercept form: 4x – 2y < 10
Answer:
y>2x-5
Step-by-step explanation:
-2y+4x<10
-2y<10-4x
divide by -2 to isolate the y
y>-5+2x
Since we are dividing by a negative the sign flips.
Our final answer is y>2x-5
