Rachel’s mother takes her to the pediatrician for her 1-year checkup. rachel is very friendly towards everyone she meets in the waiting room; she didn’t show any reaction when her mother left her in the room nor upon her mother’s return. according to ainsworth, these are indicators that rachel isa. securely attachedb. ambivalently attachedc. avoidantly attachedd. unattached

c. Avoidantly attached

Explanation:

According to Ainsworth, Rachel's lack of reaction is an indicator that Rachel is avoidantly attached to her mother. When children are avoidantly attached they do not seek comfort in their parents, because parents have shown that they are emotionally unavoidable for them. How the first caregivers interact with an infant during the first few months of its life determines the type of attachment. If the parent is unavoidable this will create an insecure attachment.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7
