Answer: What is the distance formula is that it's the formula used in Mathematics such as Pre-Algebra, Algebra 1, Geometry, Algebra 2, Trigonometry, and Pre-Calculus, also Calculus to help you find the distance between 2 points in a coordinate plane or the length of a segment. How you do the distance formula is you subtract the 2nd x coordinate by the 1st one, next you add the 2nd y coordinate to the 1st one, then the answer you get you evaluate them using the exponent of 2, lastly you add that answer and square root the answer you get to the approximate or closest decimal or whole number.
Answer:
Step-by-step explanation:
Given:
2 shapes: rectangle (tray) and circle (cake tin)
We need to find the area of each shape.
We need to convert mm to cm. 1mm = 0.1cm
600mm x 0.1cm/1mm = 60cm
500mm x 0.1cm/1mm = 50cm
Area of the Tray = 60cm * 50cm = 3,000cm²
Area of the cake tin = π r²
r = d/2 = 25/2 = 12.5cm
Area of the cake tin = 3.14 * (12.5cm)²
Area of the cake tin = 3.14 * 156.25cm²
Area of the cake tin = 490.625cm²
Area of the tray ÷ Area of the cake tin = number of cake tins that fit
3,000cm² ÷ 490.625cm² = 6.11 or 6 cake tins.
Only 6 cake tins Jenny can fit on the oven tray at one time.
34) (t-4)+(-4t+1)
Answer: -3t-3
36) 3(x^3-3x^2)+2
Answer: 3x^3-9x^2+2
38) (3x-1)(x^3-2-2x)
Answer: 3x^4-x^3-6x^2-4x+2
Answer:
Step-by-step explanation:
Let the base = x inches
So, h = 2x - 1
Area of triangle = 60 square inches
(1/2) * base *height = 60
(1/2) * x * (2x-1) = 60
x *(2x-1) = 60*2
2x² - x = 120
2x² - x - 120 = 0
2x² - 16x + 15x - 15*8 = 0
2x ( x - 8) + 15 (x -8) = 0
(x-8) (2x + 15 ) = 0
x- 8 = 0 {ignore 2x +1 as it will give negative value}
x = 8
Base = 8 inches
Height = 2*8 - 1 16 - 1 = 15 inches
