\dfrac{2}{5}(x-4)=2x\ \ \ \ |multiply\ both\ sides\ by\ 5\\\\2(x-4)=10x\ \ \ \ |use\ distributive\ property:a(b-c)=ab-ac\\\\2x-8=10x\ \ \ |add\ 8\ to\ both\ sides\\\\2x=10x+8\ \ \ \ |subtract\ 10x\ from\ both\ sides\\\\-8x=8\ \ \ \ |divide\ both\ sides\ by\ (-8)\\\\\boxed{x=-1}

Pythagorean Theorem: a^2 + b^2 = c^2

-A and B are legs of the triangle

-C is the hypotenuse

#1.

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

c = 10

#2.

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

c = 13

#4.

10^2 + 4^2 = c^2

100 + 16 = c^2

116 = c^2

c = 4\sqrt{29}

#5.

15^2 + 9^2 = c^2

225 + 81 = c^2

306 = c^2

c = 3\sqrt{34}

#6.

120^2 + b^2 = 150^2

14400 + b^2 = 22500

b^2 = 8100

b = 90

#7.

144^2 + b^2 = 194^2

20736 + b^2 = 37636

b^2 = 16900

b = 130

Hope this helps!! :)

Cortez, Inc., is expecting to pay out a dividend of $2.50 next year. After that it expects its dividend to grow at 7 percent for
tatiyna

Answer:

$10.76

Step-by-step explanation:

Present dividend, D_{1} is $2.5

Expected dividends for the next 1, 2, 3 and 4 years denoted by D_{2}, D_{3}, D_{4}, D_{5}, respectively will be

D_{2} =$2.5(1+0.07)=$2.675

D_{3} =$2.675(1+0.07)=$2.86225

D_{4} =$2.86225(1+0.07)=$3.0626075

D_{5} =$3.0626075(1+0.07)=$3.276990025

Present value will be

$2.5/(1.1)^{1} + $2.675/(1.1)^{2} + $2.86225/(1.1)^{3} + $3.0626075/(1.1)^{4} + $3.276990025/(1.1)^{5}

$2.272727273 + $2.210743802 + $2.150450789 + $2.091802131 + $2.034752982 = $10.76047698

Rounded off to 2 decimal places we get $10.76
