Answer 1

Answer:

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = - 2x² - 12x - 16

To complete the square the coefficient of the x² term must be 1

Factor out - 2 from - 2x² - 12x

f(x) = - 2(x² + 6x) - 16

add/ subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16

= - 2(x + 3)² + 18 - 16

= - 2(x + 3)² + 2 ; y = 2

What is the value for x and for y?

Answers

Answer:

20+7x=90

x=10

50+2y=90

y=20

I think
X=10
Y=20
Because a straight line is 180. So 180-20=160 from there you see that one of the angles is a right angle, you can tell this by that it has that little cube in the middle. So 160-90=70 that means that 7x=70 bit you are trying to find for x so divid 70 by 7 that equals 10.
Now to solve for why you have to plug in the information you already know. Vertical angles are congruent. That means that the that the 20 goes straight across and 7x with is actually 70 goes straight across. Now you already know the angle in the middle is 90 but this this it’s split. Since x is 10 multiply 5 by 10 then you get 50 now 90-50=40. 2y is 40 divide it by 2 to get y=20.
I’m bad at explaining so I hope I didn’t confuse you.

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000

Answers

Answer:

18.6%

Step-by-step explanation:

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000

Percentage increase is calculated as:

Final value - Initial value/ Initial value × 100

Final value = 510000

Initial value = 430000

Percentage Increase =

510000 - 430000/430000 × 100

= 80000 / 430000 × 100

= 0.1860465116 × 100

= 18.604651163 %

Approximately = 18.6 %

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

On a particularly rainy day the amount of rainfall measured in a rain gauge increased at arate of 1.5 inches each hour for 4 hours. What is the total change in the amount of rain thathas fallen after 4 hours? Can everybody rate my essay? Everybody has been love-struck at some point in life. In The Song of Wandering Aengus, William Butler Yeats experienced love at second sight. When he sees her, she is a fish. Then, she turns into a beautiful girl. The poem dwells on magic of love, and how attracted people get when they meet the glimmering someone. The poems theme is unreturned love. From the first two lines of the poem, the speaker doesnt feel well. I went out to the hazel wood,/Because a fire was in my head. The imagery of fire shapes the mood of love he wants in his life. Of course his head is not literally on fire, fire represents his desire that takes him into the hazel wood. Aengus shapes a wand, or a stick for fishing. He uses a berry as the bait to catch fish. The moth-like stars were flickering out, so you know that the time of the day is dawn. When Aengus dropped a berry in the stream, he caught a small silver fish.In the second stanza, Aengus describes laying the fish on the floor, and starting the fire. He was starting to cook something and something rustles on the floor and someone calls his name. When he turns around and expects to see the trout he sees a glimmering girl, who had apple blossom hair and she called him by his name again and then ran faded through the brightening air.The third stanza jumps forward until Aengus is an old man, and spends his whole life looking for the glimmering girl. In the second line of the third stanza, Aengus looks Through hollow lands and hilly lands he imagines he will find her and kiss and take her hand. He also puts that he and she will walk among grass together, and they will pluck the silver apples of the moon and the golden apples of the sun until the end of time. In the end, W B Yeats, poem is about the fire of love and passion. In the first two stanza Yeats is not feeling well and he meets a girl of his life. The poem starts he going to do clear his head and goes to fish, and then the the trout turn into his love and she calls his name and fades through the brightening air. The poem tells readers that if someone love someone they would do whatever it takes to find their love for them. For every 2 cars you wash, your friend washes 3 cars. You wash a total of 8 cars.

One hypothesis for the decline of the male butterflies is that a parasite infected the cells of female butterflies. The parasite was passed to offspring through the females eggs and killed the male butterfly embryos. At one point during the decline, nearly all the butterflies in the population were females, but after five years the number of males in the population increased significantly.Which explanation most likely accounts for the increase in the number of male butterflies in the five years after the initial parasite problem?Male butterflies in the population that survived were able to prey on the parasites living in the females egg cells.Female butterflies in the population that survived had a genetic adaptation that allowed them to transform into male butterflies.Male butterflies in the population that survived had a gene that made them resistant to the parasite, and they passed the gene on to their offspring.Female butterflies in the population that survived were able to protect the male eggs from the parasite and provide extra care for the male offspring.
