In the morning, the temperature in Westfield City was

Thepotemich [5.8K]

Martin's answer is wrong. The afternoon temperature in Westfield city is -10°F.

Given,

The temperature in Westfield city in morning = -2°F

The drop down temperature by afternoon = 8°F

We have to find the temperature in afternoon:

Temperature in afternoon = Temperature in morning - Drop down temperature

= -2 - 8 = -10

The afternoon temperature in Westfield city is -10°F

Martin subtracted like:

-2 - (-8) = -2 + 8 = 6

This is wrong.

That is,

We can conclude like:

Martin's answer is wrong. The temperature in Westfield city in afternoon is -10°F

To qualify for the championship, a runner must complete the race in less than 40 miles. Use t to represent the time of a runner

Elanso [62]

Answer:

The inequality which represents the situation is $t$ .

Step-by-step explanation:

Given:

Number of miles to complete the race = 40 miles.

We need to write the inequality to represent the situation.

Solution:

Let 't' represent the time of a runner who qualifies for the championship.

SO now we can say that;

time of a runner who qualifies for the championship should be less than Number of miles to complete the race.

framing in equation form we get;

$t$

Hence The inequality which represents the situation is $t$ .

If f(x)=(x+3)³+4<br> let g(x)=f(x+1)-2<br> find when g(x)=12

lana [24]

Answer:

$x=\sqrt[3]{10}-2$

Step-by-step explanation:

The composite function (f(x+1)) is moved in the x-axis by -1, you know this by solving x+1=0.

The equivalent expresion for f(x+1) is

$f(x+1)= (x-1+3)^{3}+4$

$f(x+1)=(x+2)^{3}+ 4$

Eval the above expression in g(x)

$g(x)=(x+2)^{3}+4-2$

We must find x that gives g(x)=12

The equation is the following

$12=(x+2)^{3}+2$

Grouping terms>

$(x+2)^{3} =10$

To solve for x, must apply cubic root in both sides of equation:

$\sqrt[3]{(x+2)^{3} } =\sqrt[3]{10}$

it then turns in the following>

$x+2=\sqrt[3]{10}\\$
