Find the length of a leg of a right triangle (in inches) if the other leg measures 9 in. and the hypotenuse measures 19 in. Roun

kipiarov [429]

Answer:

a = 16.733

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

a^2 + 9^2 = 19^2

a^2 = 19^2 - 9^2

a^2 = 361-81

a^2 =280

Taking the square root of each side

sqrt(a^2) = sqrt(280)

a = 16.73320053

Rounding to the nearest thousandth

a = 16.733

Find the value for x. Round your answer to the nearest hundredth. Area of the triangle = 8 ft^2

zmey [24]

Answer:

x = 3.51

Step-by-step explanation:

Since, formula to determine the area f a triangle is,

Area = $\frac{1}{2}(\text{Base})(\text{Height})$

8 = $\frac{1}{2}(x + 1)(3x - 7)$

16 = x(3x - 7) + 1(3x - 7)

16 = 3x² - 7x + 3x - 7

16 = 3x² - 4x - 7

0 = 3x² - 4x - 23

3x²- 4x - 23 = 0

By quadratic formula,

x = $\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$

x = $\frac{4\pm \sqrt{(-4)^{2}-4(3)(-23)}}{2(3)}$

x = $\frac{4\pm \sqrt{292}}{6}$

x = $\frac{4\pm 17.09}{6}$

x = 3.51, -2.18

But the length of sides can't be negative.

Therefore, x = 3.51 will be the answer.

NEED HELP FAST!!!!! The graph below compares plant height to the age of the plant, in weeks. Y=1.3x-0.8 Based on the graph, whic

salantis [7]

Answer:

C) 6 inches

Step-by-step explanation:

Given function:

$Y=1.3x-0.8$

The function compares plant height in inches to the age of plant in weeks.

So, we can say

$Y$ represents height of plant in inches.

$x$ represents age of the plant in weeks.

In order to predict the height of the plant in 5 weeks, we will plugin $x=5$ in the given function and evaluate $Y$

⇒ $Y=1.3(5)-0.8$

⇒ $Y=6.5-0.8$

⇒ $Y=5.7$ inches

Thus the approximate height of plant in 5 weeks would be $\approx 6$ inches
