Answer:

-5a-2

Step-by-step explanation:

pulg in the numbers ins h and g

a^2+4−(a+3)(a+2)

Distribute:

=a2+4+−a2+−5a+−6

Combine Like Terms:

=a2+4+−a2+−5a+−6

=(a2+−a2)+(−5a)+(4+−6)

=−5a+−2

Answer:

=−5a−2

(10)x= -7_______(i)

3x-5y= -16____(ii)

put value of x in (ii) then we have:-

3x-5y= -16

3(-7)-5y= -16

-21-5y= -16

-5y = -16+21

-5y = 5

y = 5/-5= -1

y= -1

A(t) = 500(1.0325)^t

500 is the initial deposit, t=0, A(0)=500

3.25% is the interest rate

t is in years

Let's go through the choices.

After 1 year ... A(1)=500. Don't check; it's A(0) that equals 500, A(1) is bigger.

The rate is 1.03%. Don't check; the base being exponentiated is 1 plus the rate.

Rate is 3.25%. TRUE that's why we have 1 + 0.0325 as the base.

Rate is 5%. Don't check.

Only one right answer.

AleksAgata [21]

Answer:

The right solution is "-8.25".

Step-by-step explanation:

The given values are:

Sampled people,

n = 150

Null and alternative hypotheses will be:

$H_0:p=0.53$

$Ha:p\neq 0.53$

The z-statistics will be:

⇒ $z=\frac{\bar{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }$

On substituting the values, we get

⇒ $=\frac{0.2-0.53}{\sqrt{\frac{0.53(1-0.53)}{150} } }$

⇒ $=\frac{-0.33}{\sqrt{\frac{0.24}{150}} }$

⇒ $=\frac{-0.33}{0.04}$

⇒ $=-8.25$

Which set of ordered pairs could be generated by an exponential function?

olasank [31]

Answer:

The correct option is (1,2), (0, 1), (1, 2), (2, 4).

Step-by-step explanation:

Consider the provided ordered pairs.

The exponential function is in the form of $f(x)=ab^x$

Where, a is the initial amount $a\neq 0$ and b is the rate of change b>0, $b\neq 1$

The graph of each exponential function passes through the point (0, a),

$f(0)=a\cdot b^0 = a$ and $a\neq 0$

Therefore, Option 1 and 2 and 4 are false.

Hence, the correct option is (1,2), (0, 1), (1, 2), (2, 4).
