Answer:
- 18
Step-by-step explanation:
9 ( - 2 )
= 9 x ( - 2 )
= - 18
Therefore, - 18 is the answer of the given equation.
Answer:
-18
Step-by-step explanation:
the parentheses mean to multiply, so 9 times 2 is 18, but since it is a negative and a positive that you're multiplying, then it would be negative 18
If the cost, C(x), for manufacturing x units of a certain product is given by C(x)=x2−19x+50 find the number of units manufactured at a cost of $8150
Answer:
Step-by-step explanation:
C(x) = ax2 + bx + c
C(x) = x2 -19x + 50
8150 = x2 -19x + 50
x2 -19x + 50 = 8150
x2 -19x-8100 = 0
this is a quadratic equation, solved as
x = −b ± √(b2 − 4ac) 2a ·
or
x = −(-19) ± √((-19)x(-19) − 4(1) x(-8100))/2 ·
x= 19± √((-19)x(-19) − 4(1) x(-8100))/2
x = 100

Step-by-step explanation:
Garden is in the shape of triangle.
[tex]Area of garden = \dfrac{1}{2}bh = \dfrac{1}{2}*10*6 = 5 *3 = 15 \ m^{2}[/tex]
Drive way:
length = 4 + 10 = 14m
Width = 3 m
Area = length * width = 14 * 3 = 42 sq.m
Perimeter of the property:
Length = 14 m
Width = 3 + 9 + 6 = 18 m
Perimeter = 2*(length + width) = 2*(14 + 18) = 2 * 32 = 64 m
Round 11.036568047 to 4 decimal places.
Answer:
11.0366
Step-by-step explanation:
Look at the 5th digit after the decimal place. If it is a 4 or lower, round down. If it is a 5 or higher, round up:
11.03656 - 6 is higher than 5 so the number is rounded up to 11.0366
Hope this helps!
The number is rounded up to 11.0366.
How to identify the place value of a digit in a number?The place values on left of decimal point start as ones, tens, hundreds, and so on...
The place value on right of decimal point starts from point and goes to right as tenths, hundreths and so on..
Thus, The tens means multiply by 10
Thus, The tenth means tenth part of that digit which is that digit divided by 10
If we Look at the 5th digit after the decimal place. it is a 4 or lower, round down. If it is a 5 or higher, round up:
11.03656 -
6 is higher than 5 so, the number is rounded up to 11.0366.

Insert 5 geometric means between -4 and -62 500
9514 1404 393
Answer:
Either of ...
{-20, -100, -500, -2500, -12500}{20, -100, 500, -2500, 12500}Step-by-step explanation:
For some common ratio r, the first of the "geometric means" will be -4r, the next will be -4r^2, and so on. The 5th will be -4r^5, and finally, -62500 will be -4r^6.
Solving this last relation for r gives ...
-4r^6 = -62500
r^6 = 15625
Then r can be either of ...
r = ±15625^(1/6) = ±5
For r = 5, the means are ...
-4·5 = -20, and -100, -500, -2500, -12500
For r = -5, the means are ...
-4(-5) = 20, and -100, 500, -2500, 12500

can someone please help me with how to find the perimeter and area of this
Answer:
Perimeter = 68ft
Area = 289ft²
Step-by-step explanation:
The lines on each side mean that they are all the same length - this shape is a square.
To find the perimeter, do 17 + 17 + 17 + 17 or 17 × 4. This gives you 68ft.
To find the area, you multiply the length and width → 17 × 17 = 289ft²

MARKING BRAINLEIST + 20 POINTS PLEASE HELP IS DUE TODAY
Answer: The slope is 1.5. The equation of the line is y=1.5x+3
Step-by-step explanation:
Slope is the "Rise" over the "Run" of a line. The rise is the change in y. The run is the cange in x. Take any two points. I picked (0,3) and (4,9) since they were clearly on whokle number lines. The rise is (9-3) or 6. The run is (4-0) or 4. Rise/Run = 6/4 or 1.5. The y intercept is at 3 (the value of y when x=0). The full line equation is thus y = 1.5x+3.
express 5^20 as a power of 25
The expression of 5^20 as a power of 25 can be written as 25^10.
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
We need to express 5^20 as a power of 25
If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" means this statement might change from text to text slightly.
Thus, 5^20 can be written as ;
(5^2)^10 = 25^10
Therefore, the expression of 5^20 as a power of 25 can be written as 25^10.

If x + y = 10 and x - y = 4, find the value of x² - y²
Answer:
x²-y² = 40
Step-by-step explanation:
Factorising x²-y²:
x²-y² = (x+y)(x-y)
This is due to the property that states:
a²+b² = (a+b)(a-b)
Substituting the given values into the above equation:
x²-y² = (10)(4)
= 40
Hence, x²-y² = 40

What is the slope of the line that passes through (-4, 5) and (2, -3)?
Answer:
[tex]m=\frac{-4}{3}[/tex]
[tex]y=\frac{-4}{3}x -\frac{1}{3}[/tex]
Step-by-step explanation:
Use the Slope formula...
[tex]\frac{-3-5}{2-(-4)}[/tex]
[tex]\frac{-8}{6} = \frac{-4}{3}\\\frac{-4}{3} = m[/tex]
Plug the slope into the Point-Slope formula...
[tex]y -(5) = \frac{-4}{3}(x-(-4)) \\y+5=\frac{-4}{3}x +\frac{-16}{3}\\y=\frac{-4}{3}x +\frac{-1}{3}[/tex]
What is the sum of the roots of the equation 2 x^2 + 5 x − 3 = 0?
a)-3.5
b)-2.5
C)-1.5
D)2.5
Answer:
B) -2.5
Step-by-step explanation:
2x^2 + 5x -3 = 0
(2x - 1)(x + 3) = 0
2x - 1 = 0; 2x = 1, so x = 1/2 = ROOT 1
x + 3 = 0, so x = -3 = ROOT 2
Now add the roots: -3 + 1/2 = - 2 1/2, so the answer is B.
