Given: △AKM, KD ⊥ AM , AK = 6, KM = 10, m∠AKM = 93º Find: KD

Answers

Answer 1

The length of KD in triangle △AKM, with AK = 6 and KM = 10, and m∠AKM = 93° is 10, since KD is the height of a right triangle and KM is the hypotenuse.

The question asks to find the length of KD in triangle △AKM where KD is perpendicular to AM. Given AK = 6, KM = 10, and m∠AKM = 93º, we can solve for KD using trigonometric ratios.

Since KD ⊥ AM, we have a right triangle △KDM.

We know the hypotenuse KM and angle AKM, so we can use the sine function, where sin(AKM) = opposite/hypotenuse, to find the length of KD. The sine of angle AKM (which is slightly adjusted from 93º to 90º since we are looking for the height in a right triangle) gives us:

sin(90º) = KD/ KM

We know sin(90º) = 1 and KM = 10, so:

1 = KD / 10

Therefore, KD = 10.

Graph h(x)=-|x+2|+4. Use the ray tool and select two points to graph each ray.​

Answers

The graph of the absolute value function can be seen in the image below.

How to graph the absolute value function?

Here we have the absolute value function:

h(x) = -|x + 2| + 4

To graph it we need 3 points, one at the vertex x = -2

h(-2) = -|-2 + 2| + 4 = 4

So the point is (-2, 4)

And other two points at the right and left of x = -2, I will use x = 0 and -4.

h(-4) = -|-4 + 2| + 4 = 2

h(0) = -|0 - 2| + 4 = 2

Then we have the points (0, 2) and (-4, 2)

Now to graph the function just connect the point (-2, 4) with (0, 2) and with (-4, 2) using two rays.  The graph can be seen below.

B
The annual interest rate of the savings account
C
The number of years the savings account has earned interest
D
The starting balance of the savings account

Answers

Answer:

D. the starting balance of the savings account

Step-by-step explanation:

Final answer:

The 5.00 in the function f(x) = 5.00(1.012)^x represents the starting balance of the savings account, corresponding to the initial amount of money deposited.

Explanation:

The student used the function f(x) = 5.00(1.012)^x to show how the balance in a savings account increases over time. In this context, the 5.00 represents the starting balance of the savings account. This is because the function for exponential growth in the context of compound interest is typically written as P(1 + r)^t, where P is the principal amount (the initial amount of money), r is the annual interest rate (expressed as a decimal), and t is the time the money is invested for. In the given function, the 5.00 corresponds to P, which confirms that it is indeed the starting balance. Thus, the correct answer is D.

Mika placed $4200 in a savings account which compounds interest continuously at a rate of 2.3%. How much will she have in the account after 3 years? Round to the nearest dollar.

Answers

Final answer:

Mika placed $4200 in a savings account which compounds interest continuously at a rate of 2.3%. To find out how much she will have after 3 years, we use the formula for continuous compound interest and find that the total in the account, rounded to the nearest dollar, is $4513.

Explanation:

The subject is continuous compound interest, which differs slightly from simple interest. In Mika's case, she placed $4200 in a savings account which compounds interest continuously at a rate of 2.3%. To calculate the total amount after 3 years, we use the formula A = P * e^(rt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal), and t is the time in years.

So A = $4200 * e^(0.023 * 3). When we calculate this, we find that the total in the account, rounded to the nearest dollar, is $4513.

4 siblings split their inheritance in the ratio of 2:4:6:8. the inheritance is $40,000. how much does each sibling receive for his share

Answers

Answer:

First Sibling gets $4000

Second Sibling gets $8000

Third Sibling gets $12,000

Fourth Sibling gets $16,000

Step-by-step explanation:

A ratio of 2:4:6:8 means that

First sibling gets 2 parts of total

Second sibling gets 4 parts of total

Third sibling gets 6 parts of total

Fourth sibling gets 8 parts of total

Now, how many parts are there??

2 + 4 + 6 + 8 = 20 parts

Now, we divide the total inheritance ($40,000) in 20 parts, so each part is worth:

40,000/20 = $2000

Hence,

First Sibling gets = 2000 * 2 = $4000

Second Sibling gets = 2000 * 4 = $8000

Third Sibling gets = 2000 * 6 = $12,000

Fourth Sibling gets = 2000 * 8 = $16,000

#LearnwithBrainly

Final answer:

To find the recommended daily amount of carbohydrates, divide the amount per serving (36g) by the daily value percentage (12%) and multiply by 100. The recommended amount is 300 grams of carbohydrates per day.

Explanation:

If a nutrition label states that there are 36g of carbohydrates in each serving and this amount is 12% of the daily value, we can calculate the recommended daily amount of carbohydrates by setting up a simple equation where 36g represents 12%.

To find the full 100%, we divide 36g by 12% and then multiply by 100%.

The calculation steps are as follows:

Divide the amount of carbohydrates in one serving (36g) by the percentage they represent of the daily value (12%). This gives us the amount of carbohydrates per 1% of the daily value.

Multiply the result from step 1 by 100 to find the amount of carbohydrates representing 100% of the daily value, which is the total daily recommended amount.

Calculation:

36g / 12% = 3g per 1% of daily value

3g per 1% * 100 = 300g

Therefore, the recommended daily amount of carbohydrates is 300 grams

a) What is the system that models this situation?
b) Which of the following is a solution to the system: 4 lb peanuts and 6 lb mixture; 5 lb peanut and 5 lb mixture; 8 lb peanut and 2 lb mixture? Show your work.

Answers

Answer:

{a}p + 0.2m = 6

   0.8m = 4

or 5p + m = 30

   m = 5

{b} 5 lb peanuts and 5 lb mixture

Step-by-step explanation:

m1 → desired mixture with composition : 60% peanuts and 40% almonds and weight : 10 lb

⇒weight of peanuts in m1 = 60% × 5 = 6 lb

and weight of almonds in m1 is 4 lb

m2 → mixture with composition : 20% peanuts and 80% almonds and weight : m pounds

⇒weight of peanuts in m2 = 0.2m

and weight of almonds in m2 = 0.8m

p → weight (in pounds) of peanuts added to m2 to make m1

{a}

add p pounds of peanuts to m2 to make m1

equating weights of peanuts and almonds:

p + 0.2m = 6

0.8m = 4

{b}

equation gives m = [tex]\frac{4}{0.8}[/tex] ⇒ m = 5 lb

Using this in the [tex]1^{st}[/tex] equation:

p + 1 = 6 ⇒ p = 5 lb

Answer:

a) p + m = 10 and [tex]\frac{p + 0.2m}{0.8m} = \frac{60}{40}[/tex]

b) The mixing amount is 5 lb peanut and 5 lb mixture.

Step-by-step explanation:

Given that p pounds of peanuts and m pounds of the 80% almond and 20% peanut mixture are used to make 10 pounds of 60% peanuts and 40% of almonds mixture.

Now, we can write that p + m = 10 ........ (1)  

Now, m pounds of 80% almond and 20% peanut mixture contain 0.2m pounds of peanuts and 0.8m pounds of almonds.

Now, from the condition given it can be written that  

[tex]\frac{p + 0.2m}{0.8m} = \frac{60}{40}[/tex] .......... (2)

⇒ [tex]\frac{p + 0.2m}{0.8m} = \frac{3}{2}[/tex]

⇒ 2p + 0.4m = 2.4m

⇒ 2p = 2m

p = m  

Now from equation (1) we get p = m = 5 pounds.

a) Therefore, equations (1) and (2) are the system of equations that models the situation.

b) The mixing amount is 5 lb peanut and 5 lb mixture. (Answer)

What number is missing in the pattern?16, 8, _ , 2, 1 Scientist think colonies of Cyanobacteria called stromatolites were responsible for the introduction of oxygen into earths atmosphere ) true or false Trials in an experiment with a polygraph include 96 results that include 22 cases of wrong results and 74 cases of correct results. Use a 0.01 significance level to test the claim that such polygraph results are correct less than 80% of the time Based on the results should polygraph test results be prohibited as evidence in trials? Identify the null hypothesis, alternative hypothesis, test statistics, p value, conclusion about null hypotheses and final conclusion that address the original claim. Use the p value methos. Use the normal distribution as an approximation of the binomial distribution. A. I dentify the Null and alternative hypothesis B. The test staistic is z= (round to two decimals) C. The P value is=( rounds to four decimals) D. Identify the conclusion about the null hypotheses and the final conclusion that address the original claim. Choose (fail to reject, reject) h0. There choose(is, is not) sufficient evidence to support the claim that the polygraph result are correct less than 80% of time. answer H0: P 0.80 Ha: P < 0.80 Estimated p = 74 / 98 = 0.7551 Variance of proportion = p*(1-p)/n = 0.8(0.2)/98 =0.0016327 S.D. of p is sqrt[0.001633] = 0.0404 z = ( 0.7551 - 0.8 ) / 0.0404 = -1.1112 P-value = P( z < -1.1112) = 0.1335 Since the p-value is greater than 0.05, we do not reject the null hypothesis. Based on the results there is no evidence that polygraph test results should be prohibited as evidence in trials. 20 points for this question:Find the domain. When the concentration of PCl3(g) is increased to 1.2 M, the ratio of products to reactants is 4.0. The equilibrium constant for the reaction is 24. In which direction will the reaction shift to regain equilibrium? toward the reactants toward the products After watching a news story about a man struck by lightning on a golf course, you decide that you will never play golf to avoid being struck yourself. What is this thinking strategy called? (Temperature is negative) How many liters of NO2 (at STP) can be produced from 149 grams of Cu reacting with concentrated nitric acid, HNO3 (aq)?(The equation is balanced) Cu + 4 HNO3 Cu(NO3) 2 + 2 H2O + 2 NO263.55, 63.02, 187.57, 18.02, 46.01^ g/mol A woman is 1.6 m tall and has a mass of 50 kg. She moves past an observer with the direction of the motion parallel to her height. The observer measures her relativistic momentum to have a magnitude of 2.1 1010 kgm/s. What does the observer measure for her height? In macroeconomics courses in the 1960s and early 1970s, some economists argued that one of the U.S. political parties was willing to have higher unemployment in order to achieve lower inflation and that the other major political party was willing to have higher inflation in order to achieve lower unemployment. Such views of the trade-off between inflation and unemployment might have existed in the 1960s because the Phillips curve was widely viewed as A. upward sloping. B. vertical. C. stable. D. horizontal. Such views are rare today because A. both political parties agree that higher inflation is acceptable if it means lower unemployment. B. the Phillips curve has been found to be upward sloping. C. in the long run there is no tradeoff between inflation and unemployment. D. the Phillips curve is viewed as a policy menu and a stable relationship. Tom simplified an expression in three steps, as shown:Which is the first incorrect step and why? Step 1, all the exponents are increased by 4 Step 2, the exponents of the same base are added during multiplication Step 3, the exponents of the same base are subtracted during division Step 3, all the exponents are added during division What is the standard to slope intercept form 4x - 4y = -8 Which expression is equivalent to3(x + 6)?F. x + 3 + 6G. 3x + 6H. x+6J. 3x + 18 The price of an item yesterday was $140. Today, the price fell to $91. Find the percentage decrease. Which of the following statements are true? A. Heat is converted completely into work during isothermal expansion. B. Isothermal expansion is reversible under ideal conditions. C. During the process of isothermal expansion, the gas does more work than during an isobaric expansion (at constant pressure) between the same initial and final volumes.WHAT I KNOW:Curve C= Isothermal process and A=Isobaric processThe first law of thermodynamics is a form of conservation of energy where the change of internal energy of a closed system will be equal to the energy added to the system minus work done by the system on its surroundings. deltaU=Q-W. Isothermal process is when the temperature doesnt change and the system is in contact with a heat reservoir. delta U=0 b/c because temperature is constant so the first law can be rewritten as Q=W, because Q=W that means #1 is true, right?.I think that the process could be reversible if heat is added or lost? which would make #2 true..?Work can be calulated by equation W=PdeltaV or by the area under the PV diagram curve. so is #3 false?
