Word problem: Today the temperature dropped 13 °F. After this drop, the temperature was 74 °F. What was the original temperature outside before the drop?

Subtraction problem: x °F - 13 °F = 74 °F

Solve: x - 13 = 74
x - 13(+13) = 74 + 13
x = 87 °F

Determine the coordinates of the vertex for each quadratic function and whether the parabola has a maximum or minimum. 4. y = x²
GREYUIT [131]

Answer:

minimum, coordinates of vertex: (-3,-11)

explanation:

\sf y =x^2 +6x-2

x coordinates on vertex:

<u>solving steps</u>:

  • \sf \dfrac{-b}{2a}
  • \sf \dfrac{-6}{2(1)}
  • \sf -3

<u>Find y-coordinate on vertex:</u>

\sf y =x^2 +6x-2

\sf y =(-3)^2 +6(-3)-2

\sf y =-11

\mathrm{If}\:a < 0,\:\mathrm{then\:the\:vertex\:is\:a\:maximum\:value}

\mathrm{If}\:a > 0,\:\mathrm{then\:the\:vertex\:is\:a\:minimum\:value}

coordinates: (-3,-11) thus minimum

The first side of a triangle is twice the length of the second side; the third side is 20 feet less than three times the second
dsp73

x=2nd side

2x=1st side

3x-20=3rd side

x+(2x)+(3x-20)=106

6x-20=106

6x-20+20=106+20

6x=126

6x/6=126/6

x=21

1st side=42 ft

2nd side-21 ft

3rd side=43 ft

Pam and Meg each have a picture frame. Pam’s picture frame is a square with an area of 3 square feet. Meg’s picture frame is a c
kondaur [170]

Answer:

The circumference of Meg’s picture frame is the perimeter of Pam’s picture frame by approximately 0.65 ft

Step-by-step explanation:

Pam's picture frame : Square with area of 3 sq. foot

Meg’s picture frame is a circle with a radius, r of 1 foot.

The circumference of Meg’s picture frame is the perimeter of Pam’s picture frame by approximately feet.

Let's calculate circumference of Meg's picture frame:

Circumference c, = 2πr

r = 1 ft

c = 2 * 3.14 *1 = 6.28 ft


Now calculate Perimeter of Pam's picture frame:

A is area of square and s is the side

A = s²

s² = 3

s = √3

Permeter of square = 4s

= 4√3 = 6.93ft

Now in order to find  circumference of Meg’s picture frame is the perimeter of Pam’s picture frame, we have to find their difference.

Permimeter of square frame - Circumference of circle frame = 6.93 - 6.28 = 0.65
