Answer:

his intrest rate is 7%

Step-by-step explanation:

294/1400=0.21

0.21/3 years = 0.07

0.07=7%

1400*0.07=98

98*3 years = 294

Which points could be the vertices of the image of the rectangle after it is dilated from the origin by a scale factor of 3? Sel

Nikitich [7]

Answer:

Step-by-step explanation:

Dilating with a scale factor of 3 centered at the origin means we multiply all the coordinates by 3.

(0,2) maps onto (0,6).
(0,4) maps onto (0,12).
(3,2) maps onto (9,6).
(3,4) maps onto (9,12).

Therefore, the answers are the second option and the sixth option.

BRAINLIESTT ASAP! PLEASE HELP ME :)

Step-by-step explanation:

$\displaystyle y = Asec(Bx - C) + D$

According to this trigonometric function, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL:

$\displaystyle Phase\:[Horisontal]\:Shift → \frac{0}{4} = 0 \\ Period → \frac{2}{4}π = \frac{π}{2}$

Therefore we have our answer.

Extended Information on the trigonometric function

$\displaystyle Vertical\:Shift → D \\ Phase\:[Horisontal]\:Shift → \frac{C}{B} \\ Period → \frac{2}{B}π \\ Amplitude → |A|$

NOTE: Sometimes, your vertical shift might tell you to shift your graph below or above the midline where the amplitude is. Moreover, ALL tangent, secant, cosecant, and cotangent functions have NO AMPLITUDE.

I am joyous to assist you anytime.

The temperature was 48°F and dropped 15° in two hours.

anyanavicka [17]

Answer:

33 degrees Fahrenheit.

Step-by-step explanation:

If the temperature was 48 degrees, and it dropped 15, that means the initial temperature was subtracted by 15.

48 - 15 = 33.
