Answer:
The slope would be 13/-3 or -4.3... repeating
Step-by-step explanation:
The slope of the line passing through the points (2, −7) and (−1, 6) is (13 / 3 ).
What is the slope of the line?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
The slope of the line is calculated by the formula below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given points through which the line is passing are (2, −7) and (−1, 6). The slope of the line is calculated by the formula written below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = (6 - ( - 7 ) / ( -1 - 2 )
Slope = 13 / - 3
Slope = -13 / 3
Therefore, the slope of the line passing through the points (2, −7) and (−1, 6) is (13 / 3 ).

Answer:
what is x?
Step-by-step explanation:
Answer:
X = 5
Step-by-step explanation:
Input the y into the equation:
-3 = -2x + 7
Subtract 7 on both sides:
-10 = -2x
Divide -2 on both sides:
5 = x

Please helppp me with this math problem
Answer:
length: 38 feet
width: 10 feet
area: 380 ft²
Step-by-step explanation:
The scale between the drawing and the actual studio is 2 in : 5 ft. If we divide both sides by 2, we find that the scale is 1 in : 2.5 feet.
For the first number, 15.2 inches, if we multiply it by 2.5 and change the label to "feet", we can find the real length.
15.2 * 2.5 = 38.
The length is 38 feet.
For the width, do the same thing.
4 * 2.5 = 10
The width is 10 feet.
Area is length times width. So if we plug in the numbers we just found:
38 * 10 = 380.
The area is 380 ft²

Answer:
1/6
Step-by-step explanation:
1/6th is the answer. The cube has sides that are labeled 1 to 6. Since 4 is one number that is a possibility and there are 6 possibilities that the cube may roll another number. He has 1/6th of a chance that the number lands on 4.

Find the value of c so that the polynomial p(x) is divisible by (x-3). p(x) =-x^3+cx^2-4x+3. c=?
Answer:
[tex]\boxed{\textsf {The value of c is $\sf \dfrac{-14}{3}$. }}[/tex]
Step-by-step explanation:
A polynomial is given to us . We need to find the value of c so that it is divisible by (x-3 ) .The given polynomial to us is ,
[tex]\sf \implies p(x)=- x^3+cx^2-4x+3 [/tex]
And the factor is ,
[tex]\sf \implies g(x) = x + 3 [/tex]
Now , according to factor theorem , p(x) will be divisible by g(x) if p(-3) = 0
[tex]\sf \implies p(x)= - x^3+cx^2-4x+3 \\\\\implies\sf p(-3) = 0 \\\\\sf\implies -(-3)^3+c(-3)^2-4(-3)+3 = 0 \\\\\sf\implies 27 + 9c +12+3=0 \\\\\sf\implies 9c +42=0 \\\\\sf\implies 9c = (-42) \\\\\sf\implies c = \dfrac{-42}{9}\\\\\sf\implies \boxed{\pink{\sf c = \dfrac{-14}{3}}}[/tex]
Hence the value of c is (-14)/3 .The value of c will be equal to -14/3.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is p(x) =-x³+cx²-4x+3. The value of c will be calculated as,
p(x) =-x³+cx²-4x+3
p(-3) =-(-3)³+c(-3)²-( 4 x -3) +3
p(-3) = 27 + 9c +12 + 3
27 + 9c +12 + 3 = 0
9c = -42
c = -42/9
c = -14/3
Therefore, the value of c will be equal to -14/3.

Answer:

Step-by-step explanation:
Answer: 5.81%
Step-by-step explanation: Delta Math
A = 17700. P = 9900. t = 10
17700 = 9900e^r(10)
17700/9900 = 9900e^10r/9900
1.7878788 = e^10r
In(1.7878788) = In(e^10r)
In(1.7878788) = 10r
In(1.7878788)/10 = 10r/10

Square root of 7569 is 87
Answer:
87
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle.
The square on the hypotenuse (h) is equal to the sum of the squares on the other 2 sides, that is
h² = 60² + 63² = 3600 + 3969 = 7569 ( take the square root of both sides )
h = [tex]\sqrt{7569}[/tex] = 87

Cos A 4/5 so the answer is d
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Remark
The tangent is described as the ratio of the side opposite the reference angle divided by the side adjacent to the reference angle.
In this case
The reference angle is B
The side opposite is AC and it has a value of 4
The side adjacent is BC and it has a value of 3
Hypotenuse
If you are finding either the sine or cosine of any angle, you need the hypotenuse.
AB^2 = 4^2 + 3^2 = 16 + 9
AB^2 = 16 + 9
AB^2 = 25
Take the square root of 25
AB = 5
Cos(A)
The cos(A) = adjacent / hypotenuse
Adjacent = AC = 4
Hypotenuse = AB = 5
Cos(A) = a/h
Cos(A) = 4/5 which is D

The mass of an ornament is m grams.
The height of the ornament is h centimetres.
m is directly proportional to the cube of h.
m = 525 when h= 5
a) Work out an equation connecting m and h.
Given:
m is directly proportional to the cube of h.
m = 525 when h= 5.
To find:
The equation connecting m and h.
Solution:
m is directly proportional to the cube of h.
[tex]m\propto h[/tex]
[tex]m=kh[/tex] ...(i)
Where, k is the constant of proportionality.
Putting m = 525 and h= 5, we get
[tex]525=k(5)[/tex]
[tex]\dfrac{525}{5}=k[/tex]
[tex]105=k[/tex]
Putting k=105 in (i), we get
[tex]m=105h[/tex]
Therefore, the required equation is [tex]m=105h[/tex].
