SOLUTION: a diver jumps from a diving board that is 24 feet above the water. the height of the diver is given by h= -16(t-1.5)(t

lara [203]

Answer:

The diver will hit the water at 1.5 seconds

Step-by-step explanation:

Given

$h= -16(t-1.5)(t+1)$

Required (Missing from the question)

When will the diver hit the water?

To do this, we simply solve for t

When the diver hits the water, the height is 0 (at that point)

So, substitute 0 for h in $h= -16(t-1.5)(t+1)$

$0= -16(t-1.5)(t+1)$

Divide both sides by -16

$\frac{0}{-16} =\frac{-16(t-1.5)(t+1)}{-16}$

$\frac{0}{-16} =(t-1.5)(t+1)$

$0 =(t-1.5)(t+1)$

$(t-1.5)(t+1)=0$

Split

$t - 1.5 = 0$ or $t + 1 = 0$

Solve for t

$t = 1.5$ or $t = -1$

But time (t) can not be negative.

So:

$t = 1.5$

Hence, the diver will hit the water at 1.5 seconds

Which term is a term in this expression? A. x+4 B. -7 C. -3 D. -3x

svp [43]

Answer: -3x is a term

Step-by-step explanation: Any number that has a variable after it is a term. Another way to look at it is any grouping of a number and a variable. If the number stands alone, it's not a term, and if it is being added to something, it is an equation.

For the given graph, a. describe the end behavior,

satela [25.4K]

Answer:

See below.

Step-by-step explanation:

A)

The end behavior is basically how the function behaves as it approaches negative or positive infinity.

As the function approaches negative infinity, we can see that the graph is going up. In other words:

$f(x)\rightarrow\infty\text{ as }x\rightarrow-\infty$

As the function approaches positive infinity, we can see that the graph is going down. In other words:

$f(x)\rightarrow-\infty\text{ as }x\rightarrow\infty$

B)

In even-degree polynomials, both ends of the graph will be going the same way. In this graph, the two ends are going opposite ways so this is an odd-degree function.

C)

The number of real zeros is simply the amount of times the graph crosses the x-axis. In the graph, the function does this three times. Thus, the number of real zeros is 3.

Uma balconista vendeu 70 centímetros de tecido a um freguês. Essa balconista preencheu corretamente a nota fiscal, escrevendo:

Evgesh-ka [11]

Answer:

Step-by-step explanation:

A clerk sold 70 centimeters of fabric to a customer. This clerk correctly filled out the invoice, writing:

1 point

a) 0.07 m

b) 0.070 m

c) 0.070 cm

d) 0.70 m

The clerk sold 70cm of fabrics

So, she want to filled the invoice but it length of fabrics sold must be in metre.

From metric units

100cm = 1m

Then,

70 cm = x

100cm = 1m

Cross multiply

70 cm × 1m = x × 100cm

Divide both side by 100cm

Then,

x = 70 cm × 1 m / 100cm

cm cancel out

x = 70 × 1m / 100

x = 70m / 100

x = 0.7m.

So, the correct answer is D.

To Portuguese

O funcionário vendeu 70cm de tecidos

Então, ela deseja preencher a fatura, mas o comprimento dos tecidos vendidos deve estar em metros.

De unidades métricas

100cm = 1m

Então,

70 cm = x

100cm = 1m

Multiplicação cruzada

70 cm × 1 m = x × 100 cm

Divida os dois lados por 100cm

Então,

x = 70 cm × 1 m / 100 cm

cm cancelar

x = 70 × 1m / 100

x = 70m / 100

x = 0,7 m.

Então, a resposta correta é D.
