Full question:

In a basketball game, Elena scores twice as many points as Tyler. Tyler scores four points fewer than Noah, and Noah scores three times as many points as Mai. If Mai scores 5 points, how many points did Elena score? Explain your reasoning

Answer and explanation:

We start from known to unknown. We know that Mai scored 5 points and so we work from here.

Since Mai scored 5 points and Noah scored three times as many points then Noah's score = 3×5= 15 points

Since Tyler scored four points less than Noah, Noah's score= 15-4= 11 points

Finally Elena's score is twice that of Tyler hence Elena's score =2×11= 22 points

Multiply the polynomials.<br> (4x- + 4x + 6)(7x + 5)

SashulF [63]

$\implies {\blue {\boxed {\boxed {\purple {\sf { \: 28 {x}^{3} + 48 {x}^{2} + 62x + 30}}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$(4 {x}^{2} + 4x + 6)(7x + 5)$

$= \: 7x(4 {x}^{2} + 4x + 6) + 5(4 {x}^{2} + 4x + 6)$

$= \: 28 {x}^{3} + 28 {x}^{2} + 42x + 20 {x}^{2} + 20x + 30$

Combining like terms, we have

$= \: 28 {x}^{3} + (28 {x}^{2} + 20 {x}^{2} ) + (42x + 20x) + 30$

$= \: 28 {x}^{3} + 48 {x}^{2} + 62x + 30$

Answer:

$y = 1500(0.024)^t$

Step-by-step explanation:

Given

$a = 1500km$ -- initial area

$b = 2.4\%$ -- rate

$t = time$ --- (years)

Required

Represent as an exponential function

An exponential function has the form:

$y = ab^t$

Where

$a = initial\ value$

$b = rate$ and $b \ne 1$

$t= time$

Substitute values for a and b, we have:

$y = 1500 * (2.4\%)^t$

Convert percentage to decimal

$y = 1500 * (0.024)^t$

$y = 1500(0.024)^t$

Hence, the exponential function that represents the scenario is: $y = 1500(0.024)^t$
