please help solve h(t) =-16t^2+40t+20
​

Answer:

Step-by-step explanation:

salut :

en utilisant le theorem de Pythagore on obtient :

AC²= AB² + BC²

(a+5)² = 7²+a²

a²+10a+25 = 49+a²

10a+25 =49

10a =24

donc : a = 24/10 = 12/5 = 2.4 unit

The phase shift is C/B=5/2

We have given that the equation of  the sine wave

[tex]f(x)=sinx\\G(x)=\frac{1}{3} sin(2x-5)+1[/tex]

The formula f(x)=A sin(Bx-C)+D

by comparing the g(x) above formula

Phase shift is C/B

C=5 and B=2

Therefore the phase shift is C/B=5/2

Answer:

42

Step-by-step explanation:

Answer:

option A

Step-by-step explanation:

Here we can see that , the dimensions of the prism ( cuboid ) is 3 × 5 × 6 . If a cuboid has dimensions of l × b × h , then its TSA is ,

⇒ TSA = 2(lb + bh + hl)

⇒ TSA = 2[ (3)(5)+(5)(6)+(6)(3) ]

⇒ TSA = 2 [ 15 + 30 + 18 ]

⇒ TSA = 15 + 15 + 30 + 30 + 18 + 18

Hence the option A is correct .

Answer: 14/285

Step-by-step explanation:

B = 10

G = 8

T = 18

So its a 8/20 that 1 is a girl but then 2nd its 7/19 and 3rd 6/18 so

8/20 * 7/19 * 6/18 = 14/285

your welcome!

The exact value is x = 1/2.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given an expression as;

[tex]27^{-1/3} = \frac{9^{1/4} }{3^{r + 1}}[/tex]

Now we can see that

27 = 3³

9 = 3²

Then the power are 3(-1/3) = -1

3(1/4) = 3/4

So we have;

[tex]3^{-1} = \frac{3^{2/4} }{3^{r + 1}}\\\\3^{-1} =3^{1/2 -r - 1} \\\\3^{-1} =3^{1 -2r - 2 /2}\\\\3^{-1} =3^{-2r - 1/2}[/tex]

So,

-2 = -2r - 1

-2r = -1

r = 1/2

Answer:

2

Step-by-step explanation:

$24 equals 7 pencils, each x dollars worth, and the $10 left over: 24=7x+10.

Solve for x,  24-10=7x

14=7x

$2=x

The cost of each pencil is $2  

Answer:

$2

Step-by-step explanation:

→ Work out how much she spent

24 - 10 = 14

→ Divide it by the amount of pencils

14 ÷ 7 = 2

The answer is 4,800 square centimeters I believe... Try to check my answer just in case I'm wrong...

Answer:

Mean Absolute Deviation = 5.3333

Step-by-step explanation:

Xmean = 85

MAD = (85 - 85) + (92 - 85) + (88 - 85) + (80 - 85) + (91 - 85) + (74 - 85) /6

         =(0) + (7) + (3) + (5) + (6) + (11) /6

        = 32 /6

Mean Absolute Deviation = 5.3333

Answer:

Step-by-step explanation:

Answer:

To find the area break up the shapes:

The rectangle is A = bh which is 7*3 which is 21.

Triangle: A = 1/2(bh)

A=1/2(3*7)

A=1/2(21)

A=10.5

Now add up the areas:

21+10.5

=

31.5

The answer is 31.5 units.

Answer:

[tex]\lim_{x \to 0} =-\frac{1}{6}[/tex]

Step-by-step explanation:

The first step in evaluating a limit should be to plug in the number to see if you get a result

When you plug in 0 to all of the x's in the expression, you are left with the constants -1 on the top and 6 on the bottom of the fraction.

So there's no need to go any further, the limit as x approaches 0 is [tex]-\frac{1}{6}[/tex]

Answer:

-1/6

Step-by-step explanation:

To find the limit as x approaches 0 we can just plug in 0

for the numerator: 3*0+5*0-1 = -1

For the denominator: 4*0+2*0+6= 6

answer is just -1/6 or -.16666666666666666666667

Answer:

10 : 17

Step-by-step explanation:

Male runners = 35

Female runners = 50

Total runners = male runners + female runners

= 35 + 50

= 85 runners

What is the ratio of the number of female runners to the total number of runners?

Ratio of the number of female runners to the total number of runners = number of female runners : total runners

= 50 : 85

= 50 / 85

= 10/17

= 10 : 17

Ratio of the number of female runners to the total number of runners = 10 : 17
