Artist 52 [7]3 years ago

ok we have given three function h(x) defined in certain limits.for the first function

x≤-2 and second function -2<x≤-2 and for third function x>2

to find h(-1) we have the limit -2<x≤-2 so we need to plug -1 in the function -(x+1)²+2= -(-1+1)²+2=0+2=2.

to find h(-2) we know that we have x≤-2 so we need to plug x=-2 in tghe equation (1/4)x+2=(1/4)(-2)+2=-1/2+2=3/4.

for h(0) we know that zero lies in the limit -2<x≤2 so we need to plug x=0 in equation -(x+1)²+2=-(0+1)²+2=-(1)+2=1.

What is greater than 100 inches or 3 yards and one of the
Nutka1998 [239]
To compare units either of them have to change to be the same unit

either change inches to yards, or yards to inches.

1 yard is 36 inches, so
3 yards = 3 × 36 = 108 in

100 in < 108 in

3 yards is greater.

Empirical rule (statistics)Help please!!!
emmasim [6.3K]

The empirical rule you're referring to is the 68-95-99.7 rule, which asserts that for a normal (bell-shaped) distribution, approximately 68% of the distribution lies within 1 standard deviation of the mean; 95% lies within 2 standard deviations of the mean; and 99.7% lies within 3 standard deviations of the mean.

Let X be the random variable denoting vehicle speeds along this highway. We want to find P(61. To use the rule, we need to rephrase this probability in terms of the mean and standard deviation.

Notice that 61=70-9=70-3\cdot3, and 79=70+9=70+3\cdot3. In other words, 61 and 79 both lie exactly 3 standard deviations away from the mean, so P(61.

A triangular playground has angles with measures in the ratio 8 : 6 : 4. What is the measure of the smallest angle?
Airida [17]

Answer:

20°

Step-by-step explanation:

One way of doing this is to find the constant of proportionality, k:

8k + 6k + 4k = 90°    Then 18k = 90°, and k turns out to be 90/18, or 5.

Then the angles are 8(5), 6(5) and 4(5).  The smallest of these angles is thus 20°

Suppose log subscript a x equals 3, log subscript a y equals 7, and log subscript a z equals short dash 2. Find the value of the
enyata [817]

Answer:

<h2>24</h2>

Step-by-step explanation:

Given the following logarithmic expressions log_ax = 3, log_ay = 7, log_az = -2, we are to find the value of log_a(\frac{x^3y}{z^4} )

from\ log_ax = 3, x = a^3\\\\from\ log_ay = 7,y = a^7\\\\from\ log_az = -2, z = a^{-2}Substituting x = a³, y = a⁷ and z = a⁻² into the log function log_a(\frac{x^3y}{z^4} ) we will have;

= log_a(\frac{x^3y}{z^4} )\\\\= log_a(\dfrac{(a^3)^3*a^7}{(a^{-2})^4} )\\\\= log_a(\dfrac{a^9*a^7}{a^{-8}} )\\\\= log_a\dfrac{a^{16}}{a^{-8}} \\\\= log_aa^{16+8}\\\\= log_aa^{24}\\\\= 24log_aa\\\\= 24* 1\\\\= 24

Hence, the value of the logarithm expression is 24
