Answer:
The enlarged height of the photo must be 682 inches
Step-by-step explanation:
A customer wants to enlarge the image by 22 times
Hence, the scale factor = +22
Now, the current height of the photo = 31 inches
Therefore, to find the enlarged height : we need to multiply the scale factor of the required image by the current height of the photo.
Hence, Enlarged Height = 22 × 31
= 682 inches
So, The enlarged height of the photo must be 682 inches
(5b)(-3a)
= (5*(-3))(b*a) (combine like terms)
= -15ab
The final answer is -15ab~
Answer:
26.5 units²
Step-by-step explanation:
I am splitting the figure into a rectangle and two triangles to make this easier for me.
The rectangle is b•h so 5•4 = 20 units²
Area of triangle=1/2bh
The left triangle is 
(3•3) ---> (9) ---> 4.5 units²
The right triangle is (2•2) --->(4) ---> 2 units²
Then add it all up: 20+4.5+2 = <u>26.5</u><u> </u><u>units²</u>
Answer:
divide the interest amount by the product of the principal and time
Step-by-step explanation:
The simple interest formula is I = prt where I is the interest, p is the principal, r is the rate and t is the time (in years). Rewriting this formula so that r is the subject we get r = I / pt. Therefore the answer is divide the interest amount by the product of the principal and time.
Answer:
See below for answers and explanations
Step-by-step explanation:
Your table is a little weird, so I will try my best:
a) A linear regression equation for the line of best fit would be y-hat = 0.018x - 24.5111 where y-hat is the predicted value for the recorded weight gain (in pounds) and x is the additional daily caloric intake. You can put the data into lists and use the LinReg function on the TI-84 to get this equation.
b) It seems that as the pony's additional calorie intake increases, the weight gain also increases in pounds
c) Set x equal to 2300 and solve for y-hat:
y-hat = 0.018x - 24.5111
y-hat = 0.018(2300) - 24.5111
y-hat = 41.4 - 24.5111
y-hat = 16.8889
So our predicted value for the weight gain based on an additional 2300 calorie intake is 16.9 pounds.
