Answer:

20 percent decrease

Step-by-step explanation:

0.15 cents is 10 percent of 1.50, and that multiplied by 2 is 0.30 cents. 0.30 cents is equal to 20 percent, and the difference between 1.50 and 1.20 is 30 cents.

If ∠a = 90°, find the measures of ∠b, ∠c and ∠d.
nydimaria [60]

Answer:

m∠b = 35°

m∠c = 145°

m∠ d = 35°

Step-by-step explanation:

To find m∠b, we use Definition of Supplementary Angles:

180 - (90 + 55) = 35°

To find m∠c, we also use Definition of Supplementary Angles:

180 - 35 = 145°

To find m∠d, we use Vertical Angles Theorem:

m∠b = m∠d = 35°

Geometry, Triangle in a circle. Find X show work and explain please
nikklg [1K]

Answer: x=7

Step-by-step explanation:

By the Intersecting Secants Theorem, we know that:

(5)(x+5)=(6)(6+4)

Having this, we can find the value of "x" by solving for "x":

Applying Distributive property:

(5)(x+5)=(6)(24)\\5x+25=60

Subtract 25 from both sides of the equation:

5x+25-25=60-25\\5x=35

And finally dviding both sides of the equation by 5, we get:

\frac{5x}{5}=\frac{35}{5}\\x=7

Which function could be a stretch of the exponential decay function shown on the graph?
dezoksy [38]

Answer:

f(x) = (\frac {1}{2})^{(6x)}

Step-by-step explanation:

The given options are,

a) f(x) = 2^{(6x)}

b) f(x) = (\frac {1}{2})^{(6x)}

c) f(x) = 2 \times (\frac {1}{6})^{x}

d) f(x) = \frac {1}{2} \times (\frac {1}{6})^{x}

Now, clearly a) is a monotonically increasing function, hence discarded, and both of c)  and d) don't pass through (0, 1) hence they are also discarded.

Only b) is a decay function which does also pass through (0, 1), hence, b) is the correct option.
