What would the missing value be?

Mathematics
1 answer:
Dafna11 [192]3 years ago
6 0

Answer:

x = 9

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, 6) and (x₂, y₂ ) = (x, - 5 )

m = \frac{-5-6}{x-2} = \frac{-11}{x-2} , then

\frac{-11}{x-2} = - \frac{11}{7} ← numerators are equal, so equate the denominators

x - 2 = 7 ( add 2 to both sides )

x = 9

Step-by-step explanation:

Divide 31 by 50. 31 / 50 = 0.62.

1 - 0.62 = 0.38

Since it is a decrease in change the percent change is negative.

SpyIntel [72]

Answer:

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Step-by-step explanation:

Given

f(d) = (0.5 * 10^{-4})^d

g(H+) = -log_{10}(H+)

Required

Find the composite function g(f(d))

We have:

g(H+) = -log_{10}(H+)

Substitute f(d) for H+

g(f(d)) = -log_{10}(f(d))

Substitute f(d) = (0.5 * 10^{-4})^d

g(f(d)) = -log_{10}((0.5 * 10^{-4})^d)

Apply law of logarithm

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Hence, the function is:

g(f(d)) = -dlog_{10}(0.5 * 10^{-4})

Towers A and B are located 10 miles apart. A ranger spots a fire at a 42-degree angle from tower A. Another fire ranger spots th
steposvetlana [31]

Answer:

7.0 mi

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle C

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

A+B+C=180^o

substitute the given values

42^o+64^o+C=180^o

C=180^o-106^o=74^o

step 2

Find the measure of a

Applying the law of sines

\frac{c}{sin(C)}=\frac{a}{sin(A)}

substitute the given values

\frac{10}{sin(74^o)}=\frac{a}{sin(42^o)}

solve for a

a=\frac{10}{sin(74^o)}sin(42^o)

a=7.0\ mi
