Use the quadratic formula to solve x^2 + 3^x - 28 = 0

1 answer:

Mama L [17]3 years ago

3 0

Step-by-step explanation:

x^2 + 3x - 28 = 0

x^2 - 7x + 4x - 28 = 0

x(x-7) + 4(x-7) = 0

(x+4)(x-7)= 0

x+4=0 or x-7=0

x= -4 or x=7

sertanlavr [38]

Flat rate=y intercept
rate per mile=slope
y=3x+10 would be it

1.
3 is the value of the slope (3 dollars per mile)

2.
y intercept is (0,10)

3.
22 miles
y=3(22)+10
y=66+10
y=76

On a coordinate plane, the segment with endpoints (10, 40) and (70, 120) is

OlgaM077 [116]

Answer:

The length of the resulting segment is 500.

Step-by-step explanation:

Vectorially speaking, the dilation is defined by following operation:

$P'(x,y) = O(x,y) + k\cdot [P(x,y)-O(x,y)]$ (1)

Where:

$O(x,y)$ - Center of dilation.

$P(x,y)$ - Original point.

$k$ - Scale factor.

$P'(x,y)$ - Dilated point.

First, we proceed to determine the coordinates of the dilated segment:

( $P(x,y) = (10, 40)$ , $Q(x,y) = (70, 120)$ , $O(x,y) = (0,0)$ , $k = 5$ )

$P'(x,y) = O(x,y) + k\cdot [P(x,y)-O(x,y)]$

$P(x,y) = (0,0) +5\cdot [(10,40)-(0,0)]$

$P'(x,y) = (50,200)$

$Q'(x,y) = O(x,y) + k\cdot [Q(x,y)-O(x,y)]$

$Q' (x,y) = (0,0) +5\cdot [(70,120)-(0,0)]$

$Q'(x,y) = (350, 600)$

Then, the length of the resulting segment is determined by following Pythagorean identity:

$l_{P'Q'} = \sqrt{(350-50)^{2}+(600-200)^{2}}$

$l_{P'Q'} = 500$

The length of the resulting segment is 500.

You are building a shelf that fits in a corner in the figure the entire shelf is XYZ each unit in the coordinate plane represent

horsena [70]

Answer:

$Area = 112.5$

Step-by-step explanation:

Given

$X = (15,20)$

$Y = (15,5)$

$Z = (0,5)$

Required

Determine the area of the triangle

The area is calculated using the following formula:

$Area = |\frac{X_x(Y_y - Z_y) + Y_x(X_y - Z_y) + Z_x(X_y - Y_y)}{2}|$

Where

$(X_x,X_y) = (15,20)$

$(Y_x,Y_y) = (15,5)$

$(Z_x,Z_y)= (0,5)$

Substitute right values in the given formula:

$Area = |\frac{15(5 -5) + 15(20 - 5) + 0(20 - 5)}{2}|$

$Area = |\frac{15(0) + 15(15) + 0(15)}{2}|$

$Area = |\frac{0 + 225 + 0}{2}|$

$Area = |\frac{225}{2}|$

$Area = |112.5|$

$Area = 112.5$

<em>Hence, the area of the triangle is 112.5</em>
