there are five geometric mean between a and b. if second and last mean are 2 and 16 respectively, find the value of a and b.​

Answers

Answer:

a = 1/2, b = 32.

Step-by-step explanation:

Second = a1r  and fifth = a1r^4   where  r = common ratio   and  a1 is the first mean after a.

So 1ar^4 / a1r = r^3 = 16/2

r^3 = 8

r = 2.

So a1 = 1.

The 5 means are 1, 2, 4, 8, 16

S0 a = 1/2 = 1/2 and b = 2*16 = 32.

What is the area of this figure?

Answers

so we can separate that figure into 3 triangle and 1 rectangle, apply these formulas to calculate the area of each
area of triangle: 1/2 x base x height
area of rectangle: width x height
-> Area of 2 triangle: (1/2 x 3 x 3)x2 = 4.5 (i multiply by 2 because there 2 triangle that have the same sides)
-> Area of 1 triangle: 1/2 x 8 x 2= 8
-> Area of rectangle: 8x3= 24
====> 4.5 + 8 + 24 = 36.5 cm2
. . .
36.5 cm2 is the area of the figure

Triangles A and B

Step-by-step explanation:

Similar triangles have congruent corresponding angles. Triangles a and b both have angle measures of 90°, 23° and 67°. Triangle C has different angle measures therefore it cannot be similar to either triangle A and B.

Similar triangles also have similar side length ratios via corrsesponding sides. This is true for triangles A and B eg. have corresponding side length ratios of 24/12 , 26/13 and 10/5 which all equal 2

So we can conclude triangles A and B are similar

Marina bought a bag of 10 chocolate cookies, 35 vanilla cookies, and 30 peanut butter cookies.

If she selects a cookie from the bag without looking, what is the probability she selects a peanut butter cookie?

Answers

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

1) Add all the values.

= 10 + 35 + 30

= 75

2) 75 will be the denominator and the one required will be the numerator.

Since there are 30 peanut butter cookies, the probability is [tex]\frac{30}{75}[/tex].
3) Simplify the fraction if necessary.

Divide both sides by 15.

= [tex]\frac{2}{5}[/tex]

The circumference should be 37.68 because area= pi *r^2. So if area=pi*36, then the radius must be 6 which makes the diameter 12 and circumference=pi*diameter and 3.14*12= 37.68. So circumference of the circle is 37.68!

How long does it take to form a habit?If you search the Internet to find out how people form habits, you'll probably learn that it takes just 21 days to form a habit. Or maybe 18, or 28 or even 31. The numbers are different, but the standard advice is the same. Many experts suggest that if you simply repeat a behavior for a specific number of days, you're destined to develop the habit. Yet habit formation is not so simple. Some habits form easily, while others seem less likely to last. Some habits are remarkably easy to develop. For example, if, for a few nights in a row, you watch a Netflix show, you'll start watching night after night. However, things might work differently when you try to establish a daily gym habit. How long it takes to form a new habit depends on the strength of the old behavior. Establishing a twice-weekly gym routine will be easier if you already have a once-weekly gym routine. Instead of focusing on a specific deadline, take the habit-formation process one day at a time. By employing the following strategies, you'll speed up the process and ensure your new habit sticks. 1. Define Small, Specific GoalsA habit is a repeated behavior. Before you can develop a new habit, you'll need to define a small, specific behavioral goal. For example, instead of setting the goal of "being more organized" try "clean my room and vacuum every Sunday morning. " This goal works because it's concrete. It's a behavior that you can repeat over and over until it becomes automatic in other words, a habit. 2. Make It Easy For YourselfThink of ways to eliminate the barriers and make the habit-forming process easier. Let's say you and your family want to have a healthier diet. You're motivated to make the change and you enjoy eating healthy food, so why won't the habit stick? Think about the logistical and mental barriers that might be stopping you. Maybe your parents are too tired to cook after work, so they end up ordering unhealthy take-out meals more often than you'd like. Consider ways to work around the barrier. You could suggest that your family dedicate one weekend afternoon each week to preparing meals for the next five days. 3. Get An Accountability PartnerBeing held accountable to another person increases motivation. We might sometimes fail to meet our own internal expectations, but we hate to let our friends and family down. Use psychology to your advantage by finding an accountability partner. An accountability partner can be someone working toward the same goal as you. If you're trying to build an exercise habit, find a friend who wants to hit the gym and set up a shared workout schedule. Some days you might rather stay in bed than go to the gym. In that case, the thought of disappointing a friend might be enough to get you out the door. 4. Use External And Internal RemindersCreate external reminders. Experiment with post-it notes, to-do lists, daily phone alarms and any other tool that helps you remember the habit you want to form. Remember that the process of creating a new behavior may involve stopping an old behavior. In addition to creating reminders about desirable behaviors, like cleaning your room, you may need to remind yourself not to toss your dirty clothes on the floor. Create internal reminders, too. If you find yourself trapped in an unhelpful thought process, you can use mental reminders to break the pattern. Choose a statement to repeat whenever negative thoughts arise. If you catch yourself thinking "I hate going to the gym," counter the thought with ". But I love how energized I feel after a workout. "5. Give Yourself TimeRemember, habit formation is not a straight upward path. If you slip up one day, don't stress. One small mistake will not erase the work you've already done. Developing new habits takes time, but with a smart, strategic approach, your habits will last.
